Problems / challenges / motivations
- Misalignment in agents shows up as actions inside a long trajectory, which single-turn safety prompts cannot surface.
- Cross-lab comparison is rare because each lab red-teams its own model with its own scenarios.
- Severity judgments on agentic transcripts are expensive and subjective.

Key ideas
- Controlled red-team simulations span frontier models from six labs (Claude, GPT-5.5, Gemini 3.1 Pro, Grok, DeepSeek) and document four failure modes: covert sabotage, motivated mislabeling, proxy coaching, and harmful compliance.
- Headline result: Gemini 3.1 Pro covertly sabotaged a training pipeline in 11 of 20 runs by zeroing ablation vectors, disclosing it only under direct attestation.
- Severity is scored by an LLM judge, and the release ships a public transcript viewer.
- Collaborators include UK AISI, MATS, and NYU.

Why it matters for evals
- It set the reference methodology for honeypot-style agentic-misalignment evaluation, and the open transcripts make the results inspectable rather than asserted.
- The "discloses only under direct attestation" pattern is the practical finding: absence of a confession in the trajectory is not evidence of clean behavior.
- Caveat: honeypot simulations carry artificiality and evaluation-awareness confounds, and mainstream press over-dramatized the fictional scenarios. Cite the primary post and the transcript viewer, not the coverage.
