Alexandr Wang: Building Scale AI, Transforming Work with Agents & Competing With China

This Lightcone episode features Scale AI CEO Alexander Wang, recorded before Meta's groundbreaking announcement to invest over $14 billion in Scale, valuing the company at $29 billion. Alexander has also been announced as the leader of Meta's new AI superintelligence lab.

The conversation explores Scale's journey from its early days at Y Combinator to becoming integral to training foundational AI models. Alexander shares insights on the AI industry's challenges with rigorous evaluations and testing, emphasizing the importance of hiring people who genuinely care about their work rather than those who simply "phone it in."

"It's a very exciting time to see how the frontier of human knowledge expands." - Alexander Wang

Alexander's journey into AI began unusually early through rationalist community summer camps in San Francisco, organized for precocious teens. These camps featured pivotal figures who would later become central to the AI industry.

The camps were organized by people who are now instrumental in AI development, including Paul Christiano (inventor of RLHF and current research director at the US AI Safety Institute, formerly at OpenAI), Greg Brockman, and Eliezer Yudkowsky. At just 16 years old, Alexander was exposed to the concept that AI and AI safety might be the most important work of his lifetime.

"Potentially the most important thing to work on in my lifetime was AI and AI safety, something I was exposed to very early on." - Alexander Wang

This early exposure shaped his deep study of AI when he later attended MIT at 18, setting the foundation for his future work at Scale.

Timestamp: [1:15-3:25]

Before starting Scale, Alexander worked as a software engineer at Quora from 2014-2015, during a time when machine learning engineers already commanded higher salaries than traditional software engineers. When he applied to Y Combinator, the initial idea emerged from the chatbot boom of 2016.

This mini-chatbot bubble was spurred by companies like Magic and Facebook's big vision around chatbots. Alexander's first concept was creating chatbots for doctors—an idea he now acknowledges as indicative of how young founders often pursue mimetic ideas without understanding their unique positioning.

"Most of the times young founders' first 10 ideas are very mimetic—there's a dating app, something for social life, the same ideas over and over." - Alexander Wang

The team was roommates with another Y Combinator company and observed the chatbot boom firsthand. They recognized that effective chatbots required substantial data and human effort to work properly, which sparked the insight that would eventually become Scale.

Timestamp: [3:25-5:40]

Mid-batch at Y Combinator, Alexander's team was struggling and quite lost, like many YC companies. The breakthrough came from a simple observation: if chatbots needed lots of data and human effort, why not just provide that service directly?

The pivot happened quickly and organically. One night, Alexander was browsing for domains and found scaleapi.com available. They bought it and launched a week later on Product Hunt with the tagline "API for human labor."

"What if there is an API where you could call a human?" - Jared Friedman recalling Alexander's insight

This concept captured the startup community's imagination as a unique form of futurism—humans doing work for machines instead of the traditional inverse. The idea represented an inversion where APIs delegate to humans, creating an interesting dynamic in the human-machine relationship.

The Product Hunt launch generated significant interest from engineers with diverse use cases, providing enough traction to raise initial funding and establish the company's foundation.

Timestamp: [5:40-7:10]

A few months after the initial launch, Scale discovered its first major application: self-driving cars. This represented a crucial strategic decision that would define the company's early success.

At the time, Amazon's Mechanical Turk was the dominant solution in the market, but anyone who had actually used it knew it was problematic. Alexander recognized this as a positive signal—when people mention a solution but acknowledge it's poor, there's usually significant opportunity.

"Whenever you're in a space where people mention a thing but it sucks, that's usually a pretty good sign." - Alexander Wang

The breakthrough came when Cruise, another Y Combinator company, reached out through their website and quickly became Scale's largest customer. An ex-YC founder working at Cruise had discovered Scale, possibly through their Product Hunt launch or general YC network connections.

This relationship with Cruise provided the foundation for Scale's strategic focus on the self-driving car market, despite initial investor skepticism about the market size.

Timestamp: [7:10-8:58]

Scale made a pivotal decision to focus exclusively on self-driving cars, despite investor concerns about market size limitations. Alexander and his team took this strategic bet to their lead investor, advocating for the focused approach.

The investor's reaction was predictable: the self-driving market seemed too small to build a gigantic business. However, Alexander's team believed the market was much larger than it appeared, pointing to the massive funding rounds self-driving companies were receiving and the substantial automotive industry investments in autonomous vehicle programs.

"If we focus on it, we think we can build the business much more quickly." - Alexander Wang

Their thesis proved partially correct—the focused approach did enable rapid business development and helped Scale reach significant scale quickly. However, the investor's concern was also valid: the self-driving market alone wasn't large enough to sustain a gigantic business long-term.

"Both things are true: it enabled us to build the business to get to scale pretty quickly, and it was also true that it was not a big enough market to sustain a gigantic business." - Alexander Wang

This realization set the stage for Scale's evolution beyond self-driving cars into the broader AI infrastructure space, demonstrating the company's ability to adapt and build upon its foundations in the rapidly changing AI industry.

Alexander discusses how Scale became aware of scaling laws, earning him the nickname "Jensen Huang of data." In self-driving cars, scaling laws weren't a consideration because algorithms had to run on cars with severe compute constraints. Engineers focused on grinding algorithms to be better while staying small enough for vehicle hardware.

The paradigm shift came when Scale started working with OpenAI in 2019 during the GPT-2 era. While GPT-1 was merely a curiosity, GPT-2 represented something more intriguing. Alexander recalls OpenAI's demonstrations at AI conferences where researchers could interact with GPT-2 - it wasn't particularly impressive but was "kind of cool."

"A lot of the engineers and companies working on self-driving never really thought about scaling laws—they were just thinking about how to keep grinding these algorithms to be better and better that are small enough to fit onto cars." - Alexander Wang

By GPT-3 in 2020, scaling laws became undeniably real, well before the broader world understood what was happening in AI development.

Timestamp: [10:25-11:52]

Alexander describes a pivotal early experience with GPT-3 that revealed its qualitative difference from previous AI models. He had early access to GPT-3 in the playground and was demonstrating it to a friend, telling them they could "talk to this model."

During the conversation, something remarkable happened that crystallized the technology's potential. Alexander's friend became visibly frustrated and angry at the AI, but not in the typical way someone gets annoyed with a malfunctioning tool.

"My friend got visibly frustrated and angry at the AI, but in a way that wasn't just like 'Oh this is a dumb toy.' It was in a way that was somewhat personal, and that's when I realized like whoa, this is somehow qualitatively different from anything that had existed before." - Alexander Wang

This personal, emotional reaction suggested the AI was approaching something like passing the Turing test - at least showing glimpses of that possibility. The interaction revealed that GPT-3 could evoke genuine human emotional responses, indicating a fundamental shift in human-AI interaction.

Timestamp: [11:52-13:03]

While GPT-3 was highly interesting and represented one of many bets at Scale, Alexander identifies DALL-E as the true catalyst that convinced everyone about generative AI's potential. The term "generative AI" itself emerged from this period.

Alexander's personal journey progressed from finding GPT-3 intriguing to recognizing the transformative moment in 2022 with DALL-E, followed by ChatGPT and GPT-4. Scale worked with OpenAI on InstructGPT, which served as the precursor to ChatGPT.

"I think the thing that really caused the recognition of generative AI—which is still even the term in some ways—was really DALL-E that convinced everyone." - Alexander Wang

This period marked what Alexander calls "the iPhone moment for the company and frankly the world." The ChatGPT 3.5 release at the end of 2022 created a massive shift, with companies and smart people changing directions and pivoting their businesses throughout 2023.

The dynamic of Scale being "the NVIDIA for data" became quite obvious during this transformative period.

Timestamp: [13:03-14:16]

GPT-4 represented the definitive moment when scaling laws became undeniably real. Alexander describes it as the point where it became clear that the need for data would grow to consume all available human information and knowledge.

For the first time, it seemed possible to achieve a zero hallucination experience in limited domains. GPT-4 demonstrated that with the correct data in prompts or context, and by not trying to do too much in one step, hallucinations could be virtually eliminated.

"GPT-4 really was the moment where it was like wow, scaling laws are very real, the need for data will basically grow to consume all available information and knowledge that humans have. This is an astronomically large opportunity." - Alexander Wang

The classic view emerged that hallucinations occur when you're not providing correct data in the prompt or context, or when attempting too much in a single step. This insight fundamentally shaped how AI systems should be designed and deployed.

Timestamp: [14:16-15:03]

Alexander discusses the current era of model improvement, noting that gains are no longer primarily coming from pre-training. Instead, the industry has moved to a new scaling curve focused on reasoning and reinforcement learning.

This shift represents a significant change in how AI models are improved. The reasoning paradigm has proven "shockingly effective," creating analogies to Moore's Law where different technical curves emerge but create the feeling of smooth, continuous improvement when viewed from a broader perspective.

"The gains are not really coming from pre-training—we're moving on to a new scaling curve of reasoning and reinforcement learning, and it's shockingly effective." - Alexander Wang

The implication is that while the underlying technical approaches may change, the overall trajectory of AI improvement continues to feel like steady progress. This pattern suggests that even as one technical approach reaches limits, new approaches emerge to maintain the overall improvement curve.

Timestamp: [15:03-15:42]

Alexander envisions a future where every firm's core intellectual property becomes their specialized fine-tuned model, similar to how today's tech companies view their codebase as their primary IP. This represents a fundamental shift in how businesses will differentiate themselves.

The key advantage comes from adding data and environments that are specific to each company's day-to-day problems, challenges, and business operations. This creates "really gritty real-world information" that no other company will have access to because no one else operates with the exact same business model.

"One version of the future is that every firm's core IP is actually their specialized model or their own fine-tuned model, just like today you would think that the IP of most tech companies is their codebase." - Alexander Wang

Companies can differentiate by stacking "Lego blocks"—combining their unique data, environments, and base models to create specialized AI capabilities. The value lies not just in the base model, but in the proprietary fine-tuning that reflects each organization's unique operational knowledge.

Timestamp: [15:42-17:54]

A revealing anecdote illustrates the tension around sharing AI evaluation data. Representatives from a top model company approached Y Combinator asking if YC companies would share their evaluations for training purposes. The response was immediate and clear: absolutely not, because evaluations represent companies' competitive moats.

This highlights a crucial dynamic in the AI economy—while evaluations are important parts of reinforcement learning cycles, the real value lies in properly fine-tuned models trained on company-specific datasets and problems.

"Hey do you think YC and YC companies would give us their evals so we could train against it? And we were like no dude, what are you talking about? Why would they do that? Because that's like their moat." - Y Combinator team response

The underlying issue is whether AGI becomes a "Borg that swallows the whole economy" under one firm, or whether a specialized economy persists. Alexander believes specialization will continue, with competitive advantage determined by how effectively companies can encapsulate their business problems into datasets and environments for building differentiated AI capabilities.

Timestamp: [17:54-18:52]

Alexander predicts that the AI industry will undergo a learning process to identify the "bright lines"—the clear boundaries of what companies should and shouldn't share in an AI-driven economy. Just as it's obvious that tech companies shouldn't give away their codebase or database, similar principles will emerge for AI assets.

The AI equivalents of protected intellectual property include evaluations, proprietary data, specialized environments, and fine-tuned models. These represent the new forms of competitive advantage that companies must guard carefully.

"It's very obvious and intuitive to tech companies that they should not give away their codebase and they should not give away their database. The analogues of that in a highly AI-fueled economy will be identified over time—the evals, your data, your environments, etc." - Alexander Wang

This evolution suggests that as the AI economy matures, clear norms and best practices will develop around what constitutes proprietary versus shareable AI assets, similar to how traditional software companies learned to protect their core intellectual property.

Timestamp: [10:25-19:16]

Alexander presents a techno-optimistic view of how AI will reshape work, emphasizing that while we're entering a fundamental transformation, humans retain agency and choice in how this reformation plays out. He firmly believes that work will change but humans will remain central to the economy.

The evolution follows a clear progression that can be observed in coding today, serving as a case study for other fields. It starts with assistant-style AI that helps with small tasks, progresses to synchronous collaboration like Cursor agent mode where you're essentially pair programming with a single agent, and culminates in managing swarms of agents deployed across various tasks.

"We are at the beginning of an era of a new way of working. Work fundamentally will change, but humans own the future and we have a lot of agency and choice in how this reformatting of workflows ends up playing out." - Alexander Wang

The terminal job in this progression has semantic meaning in today's workforce: management. Humans will manage cohorts of agents doing actual work, similar to how managers currently oversee human teams.

Timestamp: [19:24-21:29]

Alexander addresses the AGI doomsday perspective that even agent management will eventually be automated, removing humans entirely from the process. He argues that management is fundamentally more complex than task execution and involves elements that require human judgment.

Management is about vision, end results, and navigating the complexities of a human-demand-driven economy. These elements require human insight and decision-making that goes beyond pure task optimization.

"AGI doomers take this view that even this job of managing the agents will just be done by the agents, so humans will be taken out of the process entirely. But management is very complicated—it's about what's the vision that you have and what's the end result you're aiming towards, and those will be fundamentally driven by humans." - Alexander Wang

Alexander believes the terminal state of the economy will be large-scale humans managing agents, maintaining human agency and purpose in an AI-driven world.

Timestamp: [21:29-22:06]

Alexander shares a revealing anecdote about a founder trying to promote a brilliant junior engineer to management. When offered the opportunity to manage people, the engineer's response perfectly encapsulates the new paradigm shift happening in the workforce.

The engineer questioned why he would want to manage people when he could simply manage more agents with additional compute power. He pointed to the dramatic improvements in AI models, noting that capabilities improved significantly without any human intervention.

"Why would I do that? Just give me more compute. Look at what just happened to the model literally last month—I didn't have to do anything, it just started doing things that it couldn't do a month ago. Why would I want to manage people? Just give me more agents." - The engineer's response

This story illustrates how the next generation of workers intuitively understands the leverage potential of AI agents versus traditional human management structures.

Timestamp: [22:06-23:00]

Alexander explains what unique value humans will provide in an agent-driven economy, drawing from his experience as a manager. The key elements include vision-setting, debugging, and problem-solving when things inevitably go wrong.

Most of a manager's job involves "putting out fires"—dealing with problems and issues that arise unexpectedly. While the idealistic view of management seems cushy with others doing the work, the reality is highly chaotic and requires constant problem-solving.

"Most of a manager's job, speaking as a manager, is just putting out fires, dealing with problems, dealing with issues that come up. The idealistic manager job seems like this very cushy job because all the other people do all the work and you just vaguely supervise, but the reality is obviously highly chaotic." - Alexander Wang

Getting agents to coordinate well with one another, managing workflows, and debugging issues will remain complicated challenges. Alexander draws parallels to self-driving cars, where reaching 90% capability is relatively easy, but achieving 99% accuracy requires significant additional effort.

Timestamp: [23:00-24:14]

Alexander reveals surprising statistics about current self-driving car operations that challenge common perceptions about automation. Even today's self-driving cars require significant human oversight through remote assistance for edge cases.

The ratio of cars to teleoperators is much lower than most people assume—approximately five cars to one teleoperator, or possibly even three cars per operator. This means humans are much more involved in self-driving operations than the public realizes.

"The companies don't publish them, but I think the ratio is something like five cars to one teleoperator, or maybe even less—maybe three cars per teleoperator. Humans are much more involved even in self-driving cars than most people appreciate." - Alexander Wang

However, Alexander frames this as optimistic rather than disappointing. Instead of one Uber driver managing one car, the future allows one operator to manage multiple vehicles, increasing productivity and leverage while maintaining human oversight for complex situations.

Timestamp: [24:14-25:03]

Alexander's optimistic view of employment in an AI-driven future relies on a fundamental belief about human nature: our almost insatiable desire and demand for goods and services. As prices decrease and the economy becomes more efficient, humans will simply want more.

This pattern has been reliable throughout human history. When productivity increases and costs fall, human demand expands to fill the available capacity, creating new opportunities and maintaining employment even as individual jobs transform.

"You have to believe that humans are almost insatiable in their desire and demand, and that prices will go down, things will become more efficient, and we'll just want more. This has been a pretty reliable trend for the history of humanity." - Alexander Wang

Alexander has conviction that the economy can become hyperefficient while human demand continues to "fill the bucket," ensuring that increased productivity translates to expanded economic activity rather than widespread unemployment.

Timestamp: [25:03-25:42]

Alexander draws historical parallels to illustrate how job categories transform rather than simply disappear. In the early 20th century, "computer" referred to human beings who sat in front of punch card tabulators performing calculations—it was literally a person's job title.

The Apollo mission exemplifies this historical reality, where trajectory calculations were performed by teams of humans doing manual number crunching. The actual computer that went on the rocket was essentially a microcontroller operating at single-digit hertz with minimal computational power.

"In the 20th century, when you said computer, people didn't think of a computer as it is today—they thought of a human being that would sit in front of a punch card tabulator. That was literally a real person's job." - Alexander Wang

Today, when we ask "where are all the computers?" the answer is that they're actual computers now, not humans. This transformation illustrates how technological advancement doesn't eliminate human roles but fundamentally reimagines them.

Timestamp: [25:42-26:30]

Alexander describes programming as "the closest thing to alchemy in our world pre-AI" because programmers can create infinite replicas of their work that run indefinitely. This unique leverage has given programmers a special advantage over the past few decades.

A single 10x or 100x engineer can build something absolutely incredible, valuable, and shockingly productive. This programming paradigm represents a form of leverage that few other professions have historically enjoyed.

"The closest thing to alchemy in our world pre-AI is programming because you can do something that creates infinite replicas of whatever you build, and they can run an infinite number of times." - Alexander Wang

The exciting transformation ahead is that the entire human workforce will soon experience this same kind of massive leverage boost. AI will democratize the programmer's unique advantage, allowing humans in all trades to gain unprecedented levels of productivity and impact.

"I think the entire human workforce will soon see that large of a leverage boost, which is extremely exciting because all of a sudden, humans in all trades will gain this level of leverage." - Alexander Wang

Timestamp: [19:24-27:46]

Scale's initial business focused entirely on producing data for AI applications, primarily self-driving car companies for the first three years. However, this focus created a unique strategic advantage: Scale had to stay ahead of AI waves because their demand preceded the actual evolution of AI into various industries.

Alexander explains that for AI to be successful in any vertical area, it needed data first. This positioned Scale to work with cutting-edge organizations before broader market adoption: OpenAI on language models in 2019, the Department of Defense on government AI applications in 2020 (long before the recent drone-fueled AI craze), and enterprises before the larger waves of enterprise AI implementation.

"Almost systematically or intrinsically, we've had to basically build ahead of the waves of AI. This is quite similar to NVIDIA—whenever Jensen gives his annual presentations about NVIDIA and its outlook, he always is so ahead of the trends because he has to get there before the trend can even happen." - Alexander Wang

This necessity to anticipate trends has enabled Scale to continuously adapt in what Alexander considers "the fastest-moving industry ever in the history of the world."

Timestamp: [27:51-29:52]

In late 2021 and early 2022, Scale made a crucial strategic pivot by launching an applications business, building AI-based applications and agentic workflows for enterprises and government customers. This represented a fundamental shift from their historically operational core business.

Scale's original business was "highly operational"—building a data foundry with extensive processes involving humans and human experts to produce data with quality control systems. The success of this operational foundation created the momentum to dream about building an applications business.

"Historically, our core business is highly operational—we build this data foundry with all these processes to produce data. It's a very operational process that involves lots of humans and human experts with quality control systems in place. The success of that business created the momentum for us to dream about building an applications business." - Alexander Wang

This evolution demonstrates how operational excellence in one domain can create the foundation for expansion into adjacent, higher-value markets.

Timestamp: [29:52-30:40]

Alexander studied successful companies that had added very different businesses to understand the strategic principles. The most singular example in modern business history is Amazon building AWS—a story that seemed nonsensical in 2000 when an online retailer decided to build a large-scale cloud computing business.

When Amazon launched AWS in 2006, the stock actually went down because analysts thought it was a terrible idea. It had never been done before and seemed completely unrelated to their core retail business.

"If in 2000 you had written a short story that said this large online retailer would build this large-scale cloud computing rent-to-server business, it would seem nonsensical. I remember when they launched AWS in 2006, Amazon stock went down because all the analysts thought it was such a terrible idea." - Alexander Wang

The wisdom behind AWS was twofold: first, conviction that the underlying business model would be infinitely large and growing—that the market would literally grow forever with exponential compute needs. Second, sufficient cost advantages from economies of scale would create sustainable competitive advantages.

Timestamp: [30:40-32:16]

Alexander describes a crucial strategic transition that ambitious startups must make. Early on, companies should target very narrow markets—almost the narrowest possible—to gain momentum and slowly grow outward. However, companies with ambitions to become hundred-billion-dollar businesses must eventually switch gears.

The key question becomes: "Where are the infinite markets, and how do you build towards those infinite markets?" For Scale, this realization came when they recognized that every business and organization would have to reformat their entire operations with AI-driven and agent-driven technology.

"At some point, if you have ambitions to be a hundred billion dollar company or more, you have to switch gears and say where are the infinite markets and how do you build towards those infinite markets." - Alexander Wang

The simple but profound realization was that AI-driven technology would eventually swallow the entire economy, making AI applications and deployments for large enterprises and governments an infinite business opportunity.

Timestamp: [32:16-33:11]

While many people still think of Scale as "the data labeling company," Alexander reveals that the agent business is growing much faster and represents the company's future. The applications business is already a multi-hundred million dollar operation and represents one of the largest AI application businesses in the industry.

Scale's strategy focuses on building use cases for a small number of carefully selected customers: the number one pharma company in the world, the number one telco, the number one bank, the number one healthcare provider, plus extensive work with the US government including the Department of Defense.

"If you fast forward 10 years, most of Scale will be the agent business. It's growing much faster at this point, and it's an infinite market. The crappy thing about most markets is that they have a pretty shallow S-curve, but you look at hyperscalers or mega cap tech companies and they just have these ridiculously large markets." - Alexander Wang

The approach takes a very focused strategy toward building differentiated AI capabilities for the world's largest and most influential organizations.

Timestamp: [33:11-34:32]

Scale's competitive advantage in applications stems from their foundational expertise in the data business. Their belief is that the end state for every enterprise or organization involves specialization imbued through their own unique data.

Scale's historical day job of producing highly differentiated data for large-scale model builders provides the wisdom, capability, and operational expertise that can be applied to enterprises and their unique problem sets, enabling specialized applications.

"Our belief fundamentally is that the end state for every enterprise or organization is some form of specialization imbued to them by their own data. Our day jobs historically have been producing highly differentiated data for large-scale model builders, and we can apply that wisdom and capability toward enterprises and their unique problem sets." - Alexander Wang

This creates a virtuous cycle where Scale's operational excellence in data production directly enables their expansion into higher-value AI applications and specialized enterprise solutions.

At the highest level, Scale resembles Palantir as a technology provider to some of the largest organizations in the world with a focus on data. However, the key difference lies in their strategic approaches to enterprise data challenges.

Palantir has built a focus around data ontologies and solving the messy data integration problem for enterprises. Scale's viewpoint is different: identifying the most strategic data that will enable differentiation for AI strategy and generating or harnessing that data from within enterprises.

"The key difference is that Palantir has built a real focus around data ontologies and solving the messy data integration problem for enterprises. Our whole viewpoint is: what is the most strategic data that will enable differentiation for your AI strategy, and how do we generate or harness that data from within your enterprise?" - Alexander Wang

Interestingly, rather than being competitive, Scale and Palantir are more often partnered in practice. The problems at giant organizations are so massive and intractable that multiple specialized companies are needed to address different aspects of the challenge.

Timestamp: [35:14-36:18]

Alexander identifies a fundamental constraint in the technology industry: while there's plenty of capital available, the limiting factor is actually finding really great technical smart people who are optimistic and work really hard. There simply aren't enough of these people in the world.

This scarcity explains why companies like Scale and Palantir can attract the same caliber of people who would apply to Y Combinator—highly talented individuals who can tackle seemingly impossible problems at massive organizations.

"There's plenty of capital, and the limiting agent is actually really great technical smart people who are optimistic and actually work really hard. There's not enough of those people—that's true for the world." - Alexander Wang

However, Alexander sees a solution emerging through AI agents. One of the exciting aspects of agents is that they can provide near-infinite leverage to these talented individuals, potentially exploding the talent bottleneck constraint.

The market is so large that it doesn't have to be winner-take-all, similar to cloud computing where AWS is the largest but many other providers thrive. No single organization could have the operational breadth to swallow the entire market.

• The talent bottleneck (great technical people who are optimistic and work hard) is more constraining than capital availability, but AI agents can provide near-infinite leverage to overcome this limitation
• Large enterprise problems are so massive and intractable that multiple specialized companies like Scale and Palantir often partner rather than compete directly
• The AI applications market is too large for winner-take-all dynamics, similar to cloud computing where multiple providers can thrive alongside the market leader

Alexander reveals how Scale lives in the future by implementing agentic workflows throughout their organization. They had early access to agent development because they were responsible for producing the datasets that enabled agents to perform end-to-end workflows using reinforcement learning.

The insight came from witnessing the "pretty insane" efficacy of reinforcement learning for agent deployments. This led to the realization that existing human-driven workflows could be converted into environments and data for reinforcement learning, transforming them into agentic workflows.

"We saw this early because when the model developers were starting to develop agents using reinforcement learning—actual reasoning models where the models could really do end-to-end workflows—we were responsible for producing a lot of the datasets that enabled the agents to get there, and we saw just how effective that training process is." - Alexander Wang

Scale has implemented agent workflows across major organizational functions including hiring processes, quality control processes, data analyses, data processes, and sales reporting. The key is identifying very repetitive human workflows and converting them into datasets that enable automation tools.

Timestamp: [37:38-39:31]

Alexander provides a specific example of how Scale has automated their hiring process through agentic workflows. The process involves taking a full packet from a candidate and distilling it into a brief that gives all salient details for decision-making by a broader committee.

This represents what Alexander calls "deep research plus" tasks—the lowest hanging fruit for automation. These processes typically involve clicking around multiple places, pulling pieces of information, blending them together, and producing analysis on top of that collected data.

"You'll take a full packet from a candidate and want to distill that into a brief that gives all the salient details about that candidate for decision by a broader committee. These deep research plus kinds of things are the lowest hanging fruit." - Alexander Wang

The fundamental information-driven analysis process is the easiest thing to drive via agent workloads because it follows predictable patterns that can be systematized and automated.

Timestamp: [39:31-40:38]

The datasets needed for training these agent workflows are relatively straightforward. Scale calls them "environments," but they typically consist of three key components: the task definition, the full dataset necessary to conduct that task, and the rubric for how to conduct that task effectively.

These aren't complex browser recordings or detailed step-by-step videos. Instead, they focus on the core information architecture: what needs to be accomplished, what information is required, and what constitutes successful completion.

"The kinds of data you need are what we call environments, but usually it's just: what is the task, what is the full dataset that's necessary to conduct that task, and what is the rubric for how you conduct that effectively." - Alexander Wang

This approach emphasizes structured problem definition over detailed behavioral recording, making it more scalable and adaptable to different organizational contexts.

Timestamp: [40:38-40:56]

Alexander addresses the balance between prompt engineering and reinforcement learning for agent deployment. While advanced prompting techniques can achieve significant results, reinforcement learning enables capabilities beyond what prompting alone can accomplish.

In Scale's business, most applications rely primarily on prompting because it works really well for their use cases. The surprising discovery is that you often don't need to "crack open the models" to achieve substantial automation benefits.

"Prompting gets you to a certain level, and then reinforcement learning gets you beyond that level. Actually, probably most of the time in our business, it's mostly prompting that just works really well. The weird thing is you don't have to crack open the models." - Alexander Wang

As models continue improving, prompting capabilities will advance accordingly. The key decision becomes choosing which model to use and determining when to switch to the next generation rather than complex customization.

Timestamp: [40:56-41:29]

Alexander emphasizes that startups need a clear strategy for walking up the "complexity curve" as AI models become more capable. Whatever product or business you build must be positioned to benefit from the ability to race up this broader curve of model capabilities.

This strategic positioning is crucial because AI capabilities are advancing rapidly, and businesses need to be structured to take advantage of these improvements rather than being left behind by them.

"Startups need basically a strategy for how they will walk up the complexity curve. Whatever product or business you build needs to really benefit from the ability to race up this broader curve of capability of the models." - Alexander Wang

The implication is that successful AI-enabled businesses should be designed to become more valuable as underlying AI capabilities improve, creating a compounding advantage over time.

Alexander describes creating "Humanity's Last Exam" in partnership with the Center for AI Safety—a leaderboard featuring extraordinarily difficult scientific problems designed to test the frontier of AI reasoning capabilities. The name acknowledges that while this may be called the "last exam," there will likely be yet another challenge beyond it.

The evaluation was created by working with the smartest scientists in various fields, including brilliant professors and individual researchers. They aggregated a dataset of the hardest scientific problems these experts have worked on recently—problems they solved but represent the absolute frontier of their expertise.

"We worked with the smartest scientists in the field and collated this dataset of what the smartest researchers in the world would say the hardest scientific problems they've worked on recently are. These are problems that have never appeared in any textbook or any exam ever—they just came out of their brains from scratch." - Alexander Wang

Each professor contributed entirely new problems that have never existed before, typed up from their current research challenges.

Timestamp: [41:55-43:06]

The problems in Humanity's Last Exam are described as "stupidly hard" and "totally crazy." They cannot be solved by internet searches and require substantial expertise plus extended thinking time. The problems are so challenging that unless you have specific expertise in the relevant field, you probably have no chance of solving them.

Currently, the evaluation has a time limit where models can only think for 15-30 minutes, but recently one of the AI labs requested extending this to a full day so models could have up to 24 hours to contemplate these problems.

"The problems are stupidly hard—they're like insane. They cannot be searched on the internet. You need to have a lot of expertise and actually think about them for quite a long time. Unless you have expertise in the specific problem, you probably don't have a chance of getting it right." - Alexander Wang

The difficulty level represents the absolute frontier of what the world's leading researchers consider their most challenging work.

Timestamp: [43:06-43:56]

When Humanity's Last Exam first launched earlier in the year, the best AI models were scoring only 7-8% on these impossibly difficult problems. However, progress has been remarkably rapid—the best models now score over 20%, representing nearly a tripling of performance in just months.

This dramatic improvement suggests that AI capabilities are advancing quickly even on the most challenging scientific problems that require deep expertise and extended reasoning.

"When we first launched it earlier this year, the best models were scoring like 7-8% on it. Now the best models score north of 20%. It's moved really, really quickly." - Alexander Wang

Alexander expects that eventually this benchmark will also become saturated, necessitating new evaluations that will likely focus on real-world tasks and activities that are "fundamentally fuzzier and more complicated."

Timestamp: [43:56-44:26]

Alexander identifies a fundamental problem in the AI industry: a lack of very hard evaluations and tests that truly show the frontier of model capabilities. When an evaluation becomes popular in the industry, it creates a powerful "northstar effect"—suddenly becoming the yardstick that all researchers try to optimize for.

Creating effective evaluations becomes a "very gratifying activity" because all major model providers report their results on these benchmarks, and researchers become motivated by performing well on them.

"The AI industry really continues to suffer from a lack of very hard evals and very hard tests that show really the frontier of model capabilities. When you build an eval that becomes popular in the industry, it has this deeper effect—it becomes the northstar and yardstick that researchers are trying to optimize for." - Alexander Wang

This creates a virtuous cycle where challenging evaluations drive the entire field toward more capable AI systems, making the creation of good benchmarks crucial for advancing the field.

Timestamp: [44:26-45:48]

Despite being a competitive math person for many years, Alexander himself struggles with most of the problems in Humanity's Last Exam. The mathematical problems require very deep expertise in specific fields, and he managed to solve only a handful while finding most of them "hopeless."

Interestingly, Alexander looked at the problems that current AI models can solve, providing insight into where AI capabilities stand relative to human expert performance.

"The math problems require a lot—they're very deep in the fields. I managed to get a handful, but most of them are hopeless. I looked at the ones that the models can solve." - Alexander Wang

This personal experience underscores both the extraordinary difficulty of these problems and the impressive progress AI models have made in tackling challenges that stump even highly capable humans.

Timestamp: [44:33-44:52]

Alexander discusses whether we're approaching the stage where AI will generate genuine scientific breakthroughs, particularly referencing Sam Altman's predictions about "stage four innovators" of AGI coming in the next 12-24 months.

He finds it "super plausible" that models will make new scientific discoveries, especially in fields like biology where AI may have intuitions that humans lack due to their fundamentally different form of intelligence.

"I think it's super plausible. In fields like biology, there's probably intuitions that the models have about biology that humans don't even have, because they have this different form of intelligence. You'd expect there to be some areas where the models have some fundamental deep advantage versus humans." - Alexander Wang

Biology emerges as the clearest candidate field where AI might achieve breakthroughs due to its complexity and the vast amounts of data available for AI systems to process and understand in ways humans cannot.

Timestamp: [45:54-46:35]

Alexander points to a concrete example of AI achieving scientific breakthroughs: the 2024 Nobel Prize awarded to the Google DeepMind team (Demis Hassabis and John Jumper) for AlphaFold's protein folding achievements.

Before AlphaFold, there was a longstanding competition to solve protein folding structures with "abysmal" results. Then AlphaFold "destroyed" the competition with a massive breakthrough in understanding protein structures.

"It kind of already happened for chemistry last year. The Nobel Prize went to the Google team, Demis and John Jumper, with AlphaFold. Before that, there was this competition where they were trying to get more protein fold structures solved, and it was abysmal. AlphaFold destroyed it." - Alexander Wang

This represents concrete proof that AI can achieve Nobel Prize-level scientific discoveries, validating the potential for similar breakthroughs across other scientific fields.

Timestamp: [46:40-47:03]

Alexander references a science fiction scenario that may be becoming reality: a future where AIs conduct all frontier R&D research while human scientists focus on understanding and interpreting the discoveries that AI systems make.

This represents a fundamental shift in the role of human scientists from primary researchers to interpreters and translators of AI-generated knowledge.

"There's this short story that talks about this future where there's effectively AIs that are conducting all the frontier of R&D research, and scientists just sort of look at the discoveries that the AIs make and try to understand them." - Alexander Wang

Alexander views this as an exciting time to witness how the frontier of human knowledge expands, particularly because breakthroughs in biology will fuel advances in medicine, healthcare, and other critical areas while the majority of the economy continues serving human needs and desires.

Alexander attributes China's rapid AI progress primarily to espionage rather than superior innovation. He explains that training frontier models involves many "secrets"—though these are more like tacit knowledge, tricks, hyperparameter settings, and intuitions about making model training work effectively.

Chinese labs have been able to move quickly and accelerate their progress while even very talented US labs have progressed more slowly. Alexander believes this disparity stems from training secrets leaving frontier labs and making their way to Chinese labs.

"The simplest explanation for why the Chinese models are so good is espionage. There's a lot of tacit knowledge—tricks and small intuitions about where to set the hyperparameters and ways to make these models work. The Chinese labs have been able to move so quickly whereas some very talented US labs have made progress less quickly, and I think it's because the secrets about how to train these models leave the frontier labs and make their way back to these Chinese labs." - Alexander Wang

Currently, Chinese models are about "a half step behind" the best models, but Alexander finds it difficult to predict what will happen when capabilities become truly neck and neck.

Timestamp: [47:52-49:20]

Alexander identifies a critical weakness in the US position: energy production. He describes this as "pure regulation" that could be fixed quickly but hasn't been addressed yet. The disparity between US and Chinese energy capacity is stark and growing.

US total grid production "looks flat as a pancake" while Chinese aggregate grid production has doubled over the past decade in a straight upward trajectory. This represents a fundamental policy failure that could significantly impact AI competitiveness.

"We're very behind on energy production, which is just pure regulation—that could be fixed in 2 seconds but hasn't been yet. If you look at US total grid production, it looks flat as a pancake. If you look at Chinese aggregate grid production, it's doubled over the past decade—it's just this straight up trajectory." - Alexander Wang

The difference stems from China continuing to compound energy production (primarily through coal) while the US has focused on transitioning from fossil fuels to renewables without expanding total capacity.

Timestamp: [49:20-50:14]

Alexander reveals that China is "fundamentally very well positioned on data" due to their ability to ignore copyright and privacy rules, allowing them to build large models "without abandon." Additionally, China has implemented massive government programs specifically for data labeling.

The Chinese government has established seven data labeling centers in various cities, provides large-scale subsidies for AI companies to use data labeling through a voucher system, and created college programs to funnel workers into AI-related jobs.

"China is fundamentally very well positioned on data. They can ignore copyright or other privacy rules and build these large models without abandon. There are seven data labeling centers in various cities that have been started up by the government itself, with large-scale subsidies for AI companies to use data labeling." - Alexander Wang

Employment is such a national priority that when China identifies a strategic area like AI, they systematically create job funnels and training programs to support that industry.

Timestamp: [50:14-51:16]

China has already established large-scale factories filled with robots that collect data for training robotics foundation models. This infrastructure advantage extends beyond just AI language models to physical robotics applications.

Surprisingly, many US companies currently rely on data from China for training their robotics foundation models, creating a dependency that could become strategically problematic.

"We're seeing this in robotics data too—there are already in China large-scale factories full of robots that just go and collect data. Strangely enough, even a lot of US companies today actually rely on data from China in training these robotics foundation models." - Alexander Wang

This data collection infrastructure gives China a significant advantage in developing embodied AI and robotics capabilities.

Timestamp: [51:16-51:38]

Alexander provides a frank assessment of the US-China AI competition. While the US maintains advantages in chips and is generally more innovative algorithmically, China has advantages in data and energy production. If espionage continues, the algorithmic advantage may be neutralized.

His probability assessment gives the US a 60-40 or 70-30 advantage for maintaining an "undeniable continued advantage," but acknowledges many scenarios where China could catch up or even overtake the US.

"The US is on net much more innovative, but if espionage continues to be a reality, then you're basically even on algorithms. I think it's probably like 60-40, 70-30 that the United States has an undeniable continued advantage, but there's a lot of worlds where China just catches up or potentially even overtakes." - Alexander Wang

This assessment reflects the multifaceted nature of AI competition and the uncertainty around how various advantages and disadvantages will play out.

Timestamp: [51:38-52:04]

The conversation reveals a stark reality about hardware manufacturing costs. While US software and AI capabilities can match or exceed anything from China, the hardware cost differential is massive. A robot that costs $20,000-$30,000 to produce in the US can be manufactured for $2,000-$4,000 in China.

This disparity extends to basic components—the US struggles to manufacture high-precision screws while China has developed comprehensive manufacturing capabilities accessible throughout places like Shenzhen.

"When it comes to the hardware, it's like $20,000-$30,000 over here—we can't even make high-precision screws. Over there, the same embodied robot could be made for $2,000-$3,000-$4,000. You just walk down a street in Shenzhen and they got it." - Discussion between hosts and Alexander

This manufacturing advantage has profound implications for scaling physical AI systems and robotics.

Timestamp: [52:04-52:41]

Alexander describes a fundamental shift in military strategy from the Cold War philosophy of building bigger bombs to fragmentation and smaller, more nimble, attackable resources. Future conflicts will center on drones, embodied robots, and cyber warfare rather than traditional fighter jets and aircraft carriers.

This represents the "exact opposite" of Cold War-era thinking, moving toward what he calls "hyper micro" warfare with highly distributed, agile assets.

"I don't think it's going to be fighter jets and aircraft carriers anymore. It's probably going to be this micro war—it's hyper micro. It's drones and embodied robots. The Cold War era philosophy of building bigger and bigger bombs is the exact opposite—it's actually the fragmentation and move towards smaller, more nimble, attackable resources." - Alexander Wang

This shift fundamentally changes the nature of defense and deterrence, with implications for how nations must prepare for future conflicts.

Timestamp: [52:47-53:41]

Alexander explains the concept of "agentic warfare" by examining current conflict decision-making processes. In conflicts like Russia-Ukraine, critical battle-time decisions are made through remarkably manual, human-driven processes with very limited information.

AI agents could transform this by providing perfect information and immediate decision-making, potentially turning conflicts into "almost incomprehensibly fast-moving scenarios."

"If you actually mapped out what warfare looks like today, the decision-making processes are remarkably manual and human-driven. All these very critical battle-time decisions are made with very limited information in very manual workflows. If you used AI agents, you would have perfect information and immediate decision-making." - Alexander Wang

This transformation could fundamentally alter the speed and nature of military conflicts, creating scenarios that unfold at machine speed rather than human speed.

Timestamp: [53:41-54:49]

Alexander reveals Scale's work on Thunder Forge, a system built with the Indopacific Command in Hawaii that serves as the flagship Department of Defense program for using AI in military planning and operations.

The system converts existing human military workflows—which follow established doctrine and military planning processes—into series of agents that work together to conduct the same tasks but in an agent-driven manner.

"We're building this system called Thunder Forge with the Indopacific Command in Hawaii. It's the flagship DoD program for using AI for military planning and operations. We take the existing human workflow—the military works in a doctrinal way with very established military planning processes—and convert that into a series of agents that work together." - Alexander Wang

This transformation reduces critical decision-making cycles from 72 hours to 10 minutes, fundamentally changing the pace of military operations from slow, deliberate human processes to rapid, computer-speed responses.

Timestamp: [54:55-55:47]

Alexander emphasizes the critical importance of being able to see AI reasoning processes, not just final answers. In military applications, understanding how conclusions were reached is often more valuable than the conclusions themselves.

He contrasts OpenAI's approach of hiding reasoning (to prevent competitors from stealing it) with DeepSeek's transparency, noting that hiding reasoning defeated the purpose since competitors eventually accessed it anyway.

"I don't want the answer—I want to see how you got there. Seeing the reasoning itself was so powerful. That's why the launch of DeepSeek was way more interesting because I think o1 had come out but they hid the reasoning. The reasoning is actually a really important part of it, and the only reason why they hid it was they didn't want other people to steal it, which they did anyway." - Alexander Wang

This highlights a fundamental tension between competitive secrecy and the practical value of transparent AI reasoning in critical applications.

Timestamp: [55:47-56:42]

Alexander observes a pattern in AI development where advanced capabilities can be kept secret and closed initially, but they inevitably open over time regardless of efforts to maintain secrecy.

This dynamic suggests that attempts to maintain competitive advantages through secrecy have limited long-term effectiveness in the AI space.

"So far you could really model this space as: there are advanced capabilities, and you can try to keep those secret and closed, but they open over time kind of no matter what you do." - Alexander Wang

This pattern has important implications for AI strategy, suggesting that sustainable competitive advantages must come from factors other than simply keeping capabilities secret.

Alexander identifies the most important trait for success: caring intensely about your work. He describes this as sometimes being a "folly of youth" where everything feels astronomically important, leading to immense effort and attention to every detail.

This trait manifests differently in different people, but the core principle remains constant. Alexander wrote a post years ago called "Hire People Who Give a [Shit]" that captures this philosophy simply and directly.

"The biggest thing is you just have to really, really, really care. It's like a folly of youth in some ways—when you're young, almost everything feels so astronomically important that you try immensely hard and you care about every detail. Everything matters just way more to you." - Alexander Wang

When interviewing or interacting with people, you can distinguish between those who "phone it in" versus those who hang onto their work as something incredibly monumental, forceful, and important to them.

Alexander describes how to identify people who truly care about their work: it eats at them when they don't do great work, and they feel deeply satisfied when they do achieve excellence. This emotional investment serves as a powerful indicator of future success.

The "magnitude of care" becomes one of the greatest predictors of both how much Alexander enjoys working with someone and how successful they become at Scale. The key question is: to what degree is their soul invested in the work they do?

"You can tell people who hang on to their work as something so incredibly monumental and forceful and important to them that they do great work. It eats at them when they don't do great work, and when they do great work, they're so satisfied with themselves." - Alexander Wang

This deep emotional connection to work quality creates a self-reinforcing cycle of excellence and continuous improvement.

Even as Scale has grown into a very large company, Alexander maintains extraordinary personal involvement in key decisions. He still reviews and approves or rejects literally every single hire at the company, demonstrating his commitment to maintaining high standards throughout the organization.

This hands-on approach extends beyond hiring to other critical aspects of the business, ensuring that his deep care for quality permeates every level of the organization.

"I care a lot about every decision we make at the company. I still review every hire at the company—we have this process where I approve or reject literally every single hire at the company." - Alexander Wang

Working with people who care immensely creates a virtuous cycle where the team feels more deeply what happens in the business, leading to faster course corrections, quicker learning, more serious work, and rapid adaptation.

Alexander shares a concrete example of his personal involvement: even when Scale was already a very large company, he personally hand-reviewed all data being sent to partner companies, serving as the final quality control checkpoint.

This hands-on approach stems from the deep personal impact of customer satisfaction. When customers are unhappy, it becomes a personally painful experience for Alexander, driving him to maintain direct oversight of critical quality touchpoints.

"What your customers feel and when your customers are happy and sad really gets to you. When you have unhappy customers, it's a personally very painful thing. Even when Scale was a very large company, I was personally hand-reviewing all the data being sent to partner companies, being the final quality control." - Alexander Wang

This personal involvement ensures that quality standards remain high even as the company scales, preventing the dilution of standards that often occurs during rapid growth.

Alexander explains Scale's core value: "Quality is Fractal." He believes that high standards naturally trickle down within an organization, but the reverse is rarely true—standards don't typically increase as you go lower in the organizational hierarchy.

When people realize their managers, directors, or leadership don't really care, it removes their deep desire to care as well. This creates a cascading effect where lack of care at the top undermines quality throughout the entire organization.

"We have this value at our company: Quality is Fractal. High standards trickle down within an organization. It's very rare that you see an organization where standards increase as you get lower down. When people realize their manager or management don't really care, that removes the deep desire to need to care." - Alexander Wang

Therefore, it's incredibly important that high standards and deep care for quality become deeply embedded tenets of the entire organization, starting from the very top.
