OpenAI's GPT-6 'Astra' Blog and Benchmarks Leak Before Quick Takedown

On September 4, a blog post that appeared to be an official OpenAI publication about GPT-6, codenamed "Astra," briefly went live before being urgently taken down. Several Reddit users archived the original text and benchmark screenshots before deletion, making it the most direct leak material on Astra's capabilities to date. The overall incident points to OpenAI accidentally exposing an unreleased product early, though the company has never confirmed it.

Confirmed

• Multiple users (cedricchee, saln1, and others) discovered and saved full archives of the疑似 official OpenAI GPT-6 "Astra" blog post, which subsequently disappeared from OpenAI's site
• The leaked benchmark screenshots include coding benchmark results and a screenshot of GPT-6-Astra's score on the PostTrainBench Lite leaderboard, which poster maksymandr described as "Impressive"
• Multiple posts (dolo937, haider1, and others) reflect community sentiment that Astra's results far exceed expectations
• OpenAI's services appeared to suffer a full outage that day; randlongevity posted that Astra-related pages wouldn't load, speculating it was due to heavy traffic
• RachelVT42 relayed Andrew Curran's claim: earlier rumors were true—the new model "Astra" is GPT-6

Unconfirmed

• Whether Astra is actually GPT-6, the model's name, and the authenticity of the benchmark scores are all unsupported by any official OpenAI information
• Whether the blog going live and being pulled was an accidental early release remains community speculation only
• Any causal link between the service outage and the Astra release is just internet banter and conjecture

Why it matters

• This is the most direct leaked material about OpenAI's next-generation flagship model; if genuine, it means GPT-6's official announcement is imminent
• cedricchee mocked the chaotic release process, showing that even top AI companies can fumble major launches
• If the archived benchmark scores are validated by a subsequent release, they could serve as an early reference for the new model's capabilities
