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.
