OpenRouter CTO Alex Atallah revealed Sentinel, a self-improving security agent the team built to protect users:
- Runs 24/7 across all platform activity, detecting anomalies, end-user account takeovers, and user key theft
- Continuously improves from trust & safety team signals, with a 0.05% action reversal rate (proxy for false positives) this month
- Any app can leverage its protection via OpenRouter OAuth (PKCE flow): users bring their own API key, pay for their own inference, and developers never manage keys on their behalf
- The team frames it as "real autoresearch in action" and is hiring
A rare public example of an LLM agent running production security operations with a quantified error rate.
