Open models drive vulnerability patching at scale while closed model refusals hamper defense
basedjensen · x · 2026-10-23
An exchange on open vs closed models in cybersecurity:
- The quoted argument: open-source advocates claimed open models' cyberoffense capability was fine because they'd also enable red-teaming — but reality says otherwise, and "Dario was right: cybersecurity is offense-dominated."
- Practitioner basedjensen counters from the trenches: open-source models are actively helping find and patch vulnerabilities at scale, while closed-source models' refusals make defensive use nearly impossible.
The core tension: openness turns out to be more valuable for defense than the doom argument assumed.
