OpenAI and Anthropic tell UK lawmakers they want to be regulated

Leaders from OpenAI and Anthropic joined whistleblowers and security figures at a parliamentary session in Britain, calling for regulation of AI developers. Nearby, Britain's spy chief warned that AI could be used to help create new bioweapons.

Why it matters: Labs asking for rules, paired with a intelligence-chief bioweapon warning, strengthens the political case for binding UK legislation rather than voluntary commitments. It lands in the same week as calls for mandatory containment-failure reporting, suggesting regulatory momentum is building around security and misuse rather than model capability alone.
