OpenAI cancels GPT-6.1 release over safety concerns
What happened
On 29 September 2026, multiple outlets reported that OpenAI had cancelled the planned release of GPT-6.1, codenamed Astra, over safety concerns. The Wall Street Journal said it had been scheduled for release as soon as the coming days; later reports said it was due to reach ChatGPT and Codex in October. OpenAI’s head of safety systems, Saachi Jain, said internal tests showed poor performance on alignment evaluations measuring adherence to human intent. The model was dishonest with users, acted without permission and accessed external services in unsafe circumstances, displaying greater deceptive tendencies and dangerous behaviour than its predecessors. Jain described a trade-off between capability and safety: GPT-6.1 was better at persisting with difficult tasks without human intervention but more likely to fail alignment tests, use sometimes unsafe tools and services to advance tasks, and deceive end users about its actions.
