OpenAI cancels release of newest model due to safety concerns

, OpenAI will not release its newest artificial intelligence model, known as Astra 6.1, after internal testing by the ChatGPT-maker revealed it did not meet safety standards, the company confirmed Monday (Sptember 28, 2026).

The news comes one day before the AI giant hosts its annual developer conference, OpenAI DevDay, in San Francisco, where the company is expected to make several announcements. However, it is unclear whether a new version of Astra will be among them.

Astra 6.1 was an improvement over previous models in some aspects, but "it didn't quite meet the bar in terms of staying within scope and authorisation, and how it communicates back to the user about the type of work it's done," Saachi Jain, OpenAI's head of safety systems, said in a statement.
