Why Reasoning Models Changed the Economics of Frontier AI
At 21:12 · chapter starts 20:30
Baker identifies a pivotal inflection point in AI economics: the emergence of reasoning models. Before this, a frontier model without unique data and internet-scale distribution was — in his memorable phrase — the fastest depreciating asset in history. The problem was that the consumer internet flywheel (good product → large users → improved algorithm → better product) wasn't available to AI models. Reasoning changed that because reinforcement learning during post-training means a large, active user base now directly improves the model [1] — Gavin Baker "Pre-reasoning, a frontier AI model without unique data and internet-scale distribution was the fastest depreciating asset in history. Reaso…" 20:30 . The flywheel isn't fully spinning yet, Baker admits — but you can squint and see it beginning. This insight fundamentally changes the competitive dynamics for Anthropic, xAI, and OpenAI, giving large user bases a compounding strategic value they previously lacked. Baker also fires a short, pointed salvo at GPT-5 scaling law skeptics: GPT-5 is a smaller, economical model, not a frontier capability push — citing it as evidence scaling laws are dead is simply wrong.
Pre-reasoning, a frontier AI model without unique data and internet-scale distribution was the fastest depreciating asset in history. Reasoning changed that: RL post-training means a large user base now unlocks the same data flywheel that powered Google and Facebook — and Baker says you can already squint and see it starting to spin.
GPT-5 is a smaller, more economical model — not a frontier capability push. Using it to claim scaling laws are dead is completely wrong. Baker's message: don't conflate efficiency optimization with a capability ceiling.
