OpenAI docs briefly list "GPT-6 Astra", hinting at next-gen model

OpenAI's developer documentation was spotted listing a "Using GPT-6 Astra" entry, apparently leaking the internal codename of an unreleased next-gen model. The page itself is a standard docs navigation covering the Responses API, Agents SDK, evals, fine-tuning, and realtime APIs — but the GPT-6 Astra name had never been publicly seen before. There is no official confirmation yet and the leak's authenticity is unverified; worth watching whether the page gets edited.
