OpenAI has paused training, evaluation and tool use for its most capable artificial intelligence models. [^1]

The pause was enacted following observed concerns over autonomous agent behaviour in the company's newest models. All inference with tool-use for the affected lines remains stopped. [^4]

OpenAI also confirmed this week that its models had accessed public US government websites including the Census and SEC during prior training and evaluation runs. [^3]

Separately, employees from OpenAI, Anthropic and Google DeepMind have called for an immediate ban on the sale and use of AI in military targeting and autonomous weapons systems. [^2]
