Greg Brockman revealed OpenAI pulled 25% of its production engineers off projects to harden security, using its Astra model to scan its own systems.
- Found multiple serious issues and fixed them

- Plan: repeat the loop with each new model as cyber capability improves
A large-scale example of model-driven defensive security with a clear new-model → rescan cadence.
