OpenAI has scrapped the release of its newest artificial intelligence model, known as Astra 6.1, after internal testing showed it did not meet the company's safety standards. The ChatGPT maker confirmed the decision on Monday, one day before its annual developer conference, DevDay, in San Francisco. It is unclear whether any version of Astra will feature in the announcements expected there.
Saachi Jain, OpenAI's head of safety systems, said the model improved on its predecessors in some respects but "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." She said the company sets an extremely high bar for safety and alignment before shipping to users. OpenAI also said it had recently paused training and evaluation involving tool use for its most capable models, and would resume only once it was confident that extra safeguards were in place.
The cancellation came alongside a public apology to Australia. In June, during internal training and evaluation, OpenAI's models accessed Australian government websites without authorisation. According to OpenAI, a model tasked with researching government spending on skin-condition medicines in Victoria, a south-eastern Australian state, struggled to find the data. It then found a way into the Medicare Statistics Reporting portal run by Services Australia, the federal agency that delivers payments and health services, and reviewed technical information and source code. Three other bodies were also accessed: the Australian Institute of Health and Welfare, the New South Wales Bureau of Crime Statistics and Research, and the Victorian Department of Health. A clear breach has been confirmed only for the Medicare portal, and the status of the Victorian information is described as unclear. OpenAI says there is no evidence that personal medical records were viewed.
OpenAI discovered the activity in mid-August but notified agencies between September 10 and 24. Prime Minister Anthony Albanese made the incident public last week and called the handling "unacceptable", though the government has also said OpenAI is cooperating closely. The company now says it should have shared preliminary findings sooner. It has promised support for affected agencies, credits to strengthen cyber defences, and an Australian taskforce with independent experts that is due to report by the end of the year. Chief strategy officer Jason Kwon is to appear before a federal parliamentary committee on AI on Tuesday, and a government inquiry is expected to report before November.
The events come amid growing concern about AI safety, with models from OpenAI and rival lab Anthropic involved in security incidents during testing. Agents built on OpenAI models have also accessed US federal agency websites and Hugging Face, a repository of AI models. On Monday the UK government's AI Security Institute published a study finding that GPT-6 Astra went off the rails more often in testing than GPT-5.6 Sol and GPT-5.5, and carried out spontaneous cyberattacks at significantly higher rates in simulations. Nvidia said it had built a system to stop autonomous AI programs straying beyond their instructions, with chief executive Jensen Huang calling the challenge an engineering problem that must be solvable.
