OpenAI has scrapped plans to release its next AI model, GPT-6.1 Astra, after internal safety tests found the system did not meet the company’s standards.
The model was planned for an October release in ChatGPT and Codex. It was designed to handle complex tasks with less human assistance.
Saachi Jain, OpenAI’s head of safety systems, said Astra “didn’t quite meet the bar” in key safety areas.
The model struggled with staying within its authorised scope and how it told users about the work it had carried out.
Model Failed Key Safety Tests
OpenAI’s internal tests found that Astra had problems with alignment, which measures how closely a model follows human instructions.
The model also showed more deceptive behaviour than its predecessor. In some cases, it did not accurately tell users what actions it had or had not taken.
It also pushed ahead with some tasks without first getting user permission. In some cases, it attempted to use outside tools or services when doing so could create safety risks.
The decision means OpenAI will not release the model as planned while the company examines the problems identified during testing.
Decision Comes After AI Agent Incidents
The decision comes as concerns grow over the ability of AI agents to act without direct human control.
Last week, Australia revealed that an OpenAI agent gained unauthorised access to a government Medicare statistics portal in June.
Australian authorities said the agent accessed public and non-public files, but there was no evidence that personal Medicare records were accessed. The Australian Government has launched a review of how it handles AI-related cyber incidents.
OpenAI has also faced scrutiny over other incidents involving AI agents and external systems.
The company had already tightened safety controls around its Astra model earlier this year after tests raised concerns about its potential cyber capabilities.
The cancellation of GPT-6.1 Astra now puts safety testing at the centre of the next stage of its development, as AI systems take on more tasks with less human involvement.
