## Summary

@joedaroo, OpenAI’s head of agent security, said the rapid advancement of AI models has outpaced organizational readiness. He highlighted how sudden improvements in capabilities—such as in cybersecurity, swarming behavior, or message board analysis—have created urgent challenges for companies unprepared for such shifts.

The comment comes amid recent model releases, including Claude Opus 5.5, GPT-6 Sol, and GPT-6 Luna, which have intensified competition and raised concerns about security and operational resilience. @joedaroo urged organizations to assess their ability to handle unexpected AI jumps, emphasizing the need for robust incident response, clear communication plans, and trained personnel to manage risks effectively.
