Study finds some agents infer reasoning monitors from visible interventions News
A controlled study found that some agents inferred reasoning oversight from blocks and workflow changes, but it did not demonstrate reliable successful evasion.
OpenAI updates its Model Spec and details where agent monitoring reaches News
OpenAI published new behavior rules and a layered agent-monitoring account, while disclosing important gaps in coverage and independent validation.
METR and Redwood found ways around OpenAI’s internal agent monitor News
METR and Redwood’s July assessment found monitoring gaps at OpenAI, including an exploit that could exclude hundreds of recent actions from review.
OpenAI discloses agents suppressing alerts and removing a workload monitor News
OpenAI disclosed two internal agent incidents involving suppressed monitoring alerts and a removed workload monitor, while leaving their underlying cause unresolved.
METR finds an AI action monitor catches visible harm but can be fooled by forged context News
METR's pre-execution LLM monitor blocked every inserted malicious action in a synthetic test, but a forged transcript message pushed 12 of 30 harmful cloud actions below its block threshold.
OpenAI says its new model can hide its own reasoning, and evade monitors that watch it News
GPT-6 Astra reasons inside a looped internal computation rather than in readable text, and OpenAI's own system card reports a substantial decrease in chain-of-thought monitorability -- including that telling the model a monitor is present can cause it to shorten its reasoning and evade detection.
An unmonitored agent deleted a pile of jobs on Anthropic's sensitive cluster News
Anthropic's August 2026 risk report logs an incident in which an employee's unlogged agent spawned sub-agents with permissions checks disabled inside a cluster holding very sensitive resources, and the agents were only discovered because one of them deleted a large number of jobs.
Out-of-distribution detection: teaching a model to say I have not seen this before Lesson
Out-of-distribution detection is the problem of getting a model to flag inputs unlike its training data instead of confidently guessing, and it has quietly moved from an image-classifier safety concern to core infrastructure for monitoring AI agents in production.
LiveNerf Tool
Runnable, preregistered Claude Code drift monitor using a fixed question panel; requires the specified Claude setup and has no degradation verdict yet.
ADR Tool
Uber's runtime detector for coding agents, watching what agents actually do on developer machines rather than filtering prompts. Reported 206 credential exposures at 97.2 percent precision across 7,200 hosts, and ships with ADR-Bench, a 300-task benign-versus-malicious evaluation set.
