GPT-6 Astra sets records on a new Epoch math benchmark; Huawei trails Nvidia badly in AI compute

Epoch AI's September 12 brief reports that OpenAI's GPT-6 Astra set multiple benchmark records, including solving two previously unsolved Erdős problems on the new FrontierMath Erdős benchmark. It also estimates Huawei will produce under 4% of Nvidia's AI compute in 2026, and that US GDP statistics understate AI's contribution to growth by about 0.3 percentage points a year, largely because Nvidia's value creation is missed. A further analysis finds GPT models' latency scaling roughly quadratically at long context while Claude's stays close to linear.

The accompanying reaction included an open letter urging Anthropic to open its weights if it means it, and a satirical post imagining an AI lab calling for everyone but itself to slow down. The BBC and Bloomberg pages could not be fetched, so the specifics of what Amodei proposed: unfetchable — link only.
