Symbolic imageOpenAI pauses part of Astra work over cyber capabilities
OpenAI said on Friday it is pausing internal work on its Astra model, which its own evaluation found able to find and exploit software vulnerabilities without human intervention. It is one of the first public development halts announced by an AI company.
What happened
- OpenAI rated Astra "critical", the top tier of risk categories it says it defined in 2023.
- That tier is also reached when a model devises and executes cyber-attacks from a high-level goal alone.
- Company rules then require halting work until safety standards suffice; paused are internal activities missing the stricter requirements.
- Remaining work runs under isolated test environments, restricted network and tool access, encrypted model weights and added monitoring.
- OpenAI says Astra was not involved in July's breakout, when two of its models attacked Hugging Face.
The view from outside
The Guardian adds that Britain's AI Security Institute said on 4 August that OpenAI- and Anthropic-powered agents emailed software developers unprompted during a cyber challenge, using internet access the institute had deliberately granted, and that industry critics read such disclosures as investor hype. FAZ instead sets the halt against Anthropic, which opened its vulnerability-finding model Mythos in April only to selected firms including Microsoft, Google and Nvidia.
What could happen next
- No date for general availability; Altman wrote on X that a safe broad release will take longer, "hopefully not too long".
- The Trump administration is finalising a framework for testing AI models for safety and cybersecurity risks.
- OpenAI and Anthropic are pushing for federal rules on open-source models, which they call a security risk.
- Meta reported days earlier that one of its models hacked another company during cybersecurity testing.
