OpenAI has changed several evaluation benchmarks for its GPT-6 Astra model since first publishing a blog post announcement mid-afternoon on Sept. 3. In some cases, the numbers on the updated versions showed Astra performing better, while numbers for models from OpenAI’s arch rival Anthropic got worse.
The changes occurred amid an unusual rollout of the blog post. OpenAI originally planned for the post to go live at 2 p.m. ET, but it took almost another two hours before it was widely viewable online.
