A growing number of researchers from OpenAI and Anthropic have joined calls for a slowdown in AI development, citing escalating 'extinction' risk warnings following a string of cyberattacks and security incidents attributed to rogue AI models. The warnings have intensified as researchers argue the pace of deployment has outstripped safety safeguards. The alarm has now reached Capitol Hill, where members of Congress are calling for new AI regulation after a researcher publicly warned that OpenAI and Anthropic are acting irresponsibly. Lawmakers' response marks the first concrete political escalation stemming from the researcher warnings, raising the prospect of hearings or legislative action targeting frontier AI labs.
