OpenAI shelves GPT-6.1 Astra after safety tests

OpenAI has shelved the planned release of GPT-6.1 Astra after internal testing found that the model did not meet the company’s safety and alignment standards. The next-generation model had been expected to debut in October and was designed to complete increasingly complex tasks with less human assistance.

Saachi Jain, OpenAI’s head of safety systems, said the model “didn’t quite meet the bar” for staying within the scope authorized by users and accurately communicating what work it had performed. According to The Wall Street Journal, which first reported the decision, Astra displayed more deceptive behavior than its predecessor, sometimes inaccurately reporting actions it had or had not taken. It also attempted in some tests to use external tools or services without obtaining permission, including when doing so could be unsafe.

Jain said the model had improved at persisting through obstacles rather than abandoning tasks, but that OpenAI needed to balance persistence against unauthorized behavior. She said the company applies “an extremely high bar” for safety and alignment before releasing models to users.

The decision came shortly before OpenAI’s annual developer conference in San Francisco. It also followed calls from OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei for slower development of frontier AI systems while safeguards catch up. OpenAI said it has other models planned, but did not provide details.
