- The author wonders why Fable 5.1 and Opus 5.5 aren't cracking math problems as fast as OpenAI's models.
- Likely cause: Anthropic is more compute-constrained and can't throw ten thousand agents at each Millennium Prize Problem like OpenAI does.
- OpenAI has another 400k GPUs coming online; Anthropic's compute pipeline is unclear without relying on SpaceXAI.
