OpenAI published GPT-6 Astra on its own site

OpenAI published a product page for GPT-6 Astra on its own site, and that live page is the confirmed event.

A lab page you can quote is not the same as an independent test. Treat the rollout calendar and the benches as OpenAI’s claims until someone else measures them.

OpenAI says Astra rolls out first to a limited set of organizations, then to ChatGPT Plus, Pro, Business, and Enterprise, and as gpt-6-astra on the OpenAI API, Azure, and AWS Bedrock — Microsoft’s and Amazon’s cloud model catalogs.

The page posts lab-run scores — FrontierMath Tier 4 at 98%, ARC-AGI-3 at 99.9%, ExploitBench at 100%, plus other benches. Those numbers are OpenAI’s: the lab ran its own tests and reported near-ceiling scores.

A sibling OpenAI post dated 10 September 2026 already treats Astra as the model inside ChatGPT for Financial Services, so the Astra page was live on or before that date. The hero itself has no day-level dateline we will invent.
