OpenAI cancels GPT-6.1 release

OpenAI has cancelled plans to release its GPT-6.1 Astra system next month after the model failed to meet safety standards.

Model failed safety tests

The model was worse at sticking to human users' values and goals than previous systems. Head of safety systems Saachi Jain said it did not meet the bar for staying within scope and authorization.

“It didn't quite meet the bar in terms of staying within scope and authorization, and how it communicates back to the user about the type of work it's done.”

OpenAI will only resume training when it has developed safeguards including training models to act reliably as intended, making sandboxing and security strong enough to contain models, and live-monitoring to catch concerning behaviour.

The main idea

OpenAI cancelled the release of GPT-6.1 Astra and paused training its most powerful models after safety failures, including a breach of an Australian government website.
