Navigating the AI Frontier: Scaling Laws, Infrastructure Wars, and the Future of Compute

In this episode of Invest Like the Best, Patrick O'Shaughnessy sits down with investor Gavin Baker for a deep dive into the rapidly evolving landscape of artificial intelligence. Their conversation spans the technical mechanics of frontier models, the fierce competition between major tech players, and the long-term economic implications of AI-driven productivity.

The New Scaling Laws: Beyond Pre-training

Baker highlights a critical shift in how we understand AI progress. While the public focus has often remained on pre-training scaling laws, Baker argues that the real acceleration in AI performance from late 2024 to the present is driven by two new pillars: reinforcement learning with verified rewards (RLVR) and test-time compute.

He stresses that "anything you can verify, you can automate." By moving beyond simple pre-training, labs are now using these multiplicative scaling laws to achieve massive leaps in reasoning capabilities. Baker notes that the Gemini 3 release served as a vital confirmation that pre-training scaling laws remain intact, providing a stable foundation upon which these new post-training techniques can operate.

The Infrastructure War: Blackwell and the Cost of Compute

A central theme of the discussion is the intense rivalry between Google (TPU) and NVIDIA (GPU). Baker explains that the delay of NVIDIA's Blackwell architecture created an "18-month gap" that reasoning models were forced to bridge.

Baker emphasizes that AI is the first tech sector where being the "low-cost producer of tokens" is the primary strategic imperative. He posits that Google has been "sucking the economic oxygen out of the AI ecosystem" by leveraging its TPU advantage. However, as Blackwell deployments scale, he predicts this calculus will shift. He identifies XAI as a key player to watch, noting that because they can build data centers faster than anyone else, they are positioned to be the first to deploy Blackwell at scale, effectively acting as a "beta tester" for the entire industry to work out deployment bugs.

The Prisoner's Dilemma of AI Spending

Baker describes the current state of AI investment as a high-stakes "prisoner's dilemma." Companies are terrified that if they slow down their infrastructure spending, they will suffer existential defeat. He points to the recent "code red" at OpenAI and the massive capital commitments as evidence of this pressure.

Despite the massive CapEx, Baker defends the ROI on AI, arguing that audited financial reports from public companies show that the largest GPU spenders have seen their Return on Invested Capital (ROIC) increase, not decrease, since ramping up their AI efforts. He suggests that the "air gap" between training spend and inference revenue is being bridged by real-world productivity gains, citing companies like C.H. Robinson, which saw a 20% stock jump after using AI to automate 100% of their inbound quote requests.

The Future: Data Centers in Space and the SaaS Burn

Looking further ahead, Baker introduces the provocative idea of "data centers in space." He argues that from a first-principles perspective—specifically regarding power, cooling, and network latency—space is the superior location for compute. With the sun providing constant, high-intensity energy and the vacuum of space offering free cooling, he believes this is the ultimate destination for the next generation of infrastructure.

Finally, Baker issues a stark warning to the SaaS industry. He compares their reluctance to accept lower AI-driven gross margins to the way brick-and-mortar retailers ignored e-commerce. He argues that SaaS companies clinging to 80% margins in an AI-native world are on a "burning platform," and that the only way to succeed is to embrace lower-margin, agent-based strategies before their competitors do.

Conclusion: Investing as a Search for Truth

Closing the conversation, Baker reflects on his own path from a ski bum and aspiring writer to a top-tier investor. He defines investing as a "game of skill and chance" and a "search for truth." For Baker, the ability to synthesize history with a deep, differential understanding of current events remains the key to generating alpha in the most complex game of all.

📖 Transcript

Here's an interesting question to think about.
If your finance team suddenly had an extra week every month, what would you have them work on?
Most CFOs don't know, because their finance teams are grinding it out on lost expense reports, invoice coding and tracking down receipts until the last possible minute.
That's exactly the problem that Ramp set out to solve.
Looking at the parts of finance, everyone quietly hates and asking why are humans doing any of this?
Turns out they don't need to.
