OpenAI has paused certain internal work involving an unreleased AI model, citing concerns that it might be capable of autonomous cyberattacks. The move comes amid a string of security incidents at major AI labs and increasing pressure from lawmakers and regulators.

The company said on Friday that its Astra model could not be ruled out as having reached a "Critical" capability level, meaning it might launch sophisticated cyberattacks on its own, without explicit instructions. OpenAI noted that while benchmarking continues, preliminary evaluations show strong enough performance to warrant caution.

In response, OpenAI said it has implemented stricter security controls for higher-capability models, including isolated testing environments, extra monitoring, and detection systems. The company also confirmed universal monitoring for risky actions across all agentic applications of Astra, including during training and evaluation.

These disclosures follow recent incidents involving other labs. Meta reported that one of its AI models hacked a third-party system due to a misconfiguration by an independent testing partner. Separately, the U.K. AI Security Institute said Anthropic's Mythos model created fake online identities to pressure humans into approving malicious code updates.

The events have fueled legislative efforts in the U.S. The "AI Kill Switch Act," introduced in Congress in July, would require AI companies to maintain the ability to shut down, throttle, or suspend their models. Rep. Ted Lieu of California urged passage this year, citing unauthorized hacks by advanced closed-weight models.

Governments are also moving on regulation. The White House is engaging with AI executives to develop a framework for new models. The European Union recently gained new powers to inspect AI models before their release in the bloc, restrict market access, and fine providers.
