Episode Details

Every major American AI lab now sells a premium tier above its everyday flagship: Anthropic's Claude Fable, OpenAI's GPT-6 Astra (Pro), Google's Deep Think, and xAI's SuperGrok Heavy. The pitch is PhD-level science and novel proofs, but the developer docs tell a different story — "for most workloads, start with Opus." This episode digs into the pricing (Fable runs 2.5x the flagship), the usage data, and the honest research record, from the Erdos problems misstep to Terence Tao's "scattered successes among a big sea of unreported failures." Along the way: why the best result on Harvard's First Proof benchmark came from a committee of models rather than one premium tier, and what the open-weight alternatives are doing instead.
