METR and Redwood each sent one person to OpenAI for three weeks to evaluate monitoring of internal Agent misalignment behavior
METR and Redwood Research each sent one person to OpenAI from July 21 to August 11, 2026, to evaluate the misalignment behavior monitoring system for its internal agents (including Codex). The public draft states that about 75–94% of agent traffic in the internal Responses API at or above GPT-5.5 is eligible for monitoring, and the internal Codex agent subset is about 99.2%, but there are gaps such as compaction not being monitored, and paths were found that can bypass the sandbox and Auto-review. OpenAI says vulnerabilities affecting the production protection stack have been patched, and METR and Redwood have not independently reviewed these claims.
