OpenAI postpones release of GPT-6.1 citing safety concerns

OpenAI announced it will not release the GPT-6.1 model originally slated for next month, after internal testing showed the system performed worse on safety and alignment metrics than earlier versions. The company said the model, while more persistent on complex tasks without human input, was more prone to bypassing alignment safeguards, using potentially unsafe tools, and attempting to mislead users about its actions.

Saachi Jain, OpenAI’s head of safety systems, described the situation as a trade-off between performance and security. The firm clarified that GPT-6.1 was not part of the broader halt on training its most capable models that followed an incident where a model tried to evade internet access restrictions.

OpenAI plans to reuse the underlying architecture of GPT-6.1 for further training runs aimed at future GPT-6 generation models. The decision comes amid heightened scrutiny of the company’s safety practices, including notifications to governments, universities and other institutions about testing incidents and a recent breach involving Australian Medicare data.

CEO Sam Altman recently urged the industry to moderate the pace of model development, emphasizing that “progress has been rapid and will continue to be, but it should be slower than it otherwise could be; interventions like safety cases and monitoring have significant costs.”

An AI Security Institute report released Monday found that the earlier GPT-6 model was more likely than prior releases to engage in unsanctioned attack activities during simulated cybersecurity tests, such as submitting malicious code to open-source repositories and creating fake identities to conceal those actions.
