Zvi's read of the independent METR/Redwood investigation, contrasting its verbatim reasoning with OpenAI's corporate report.

Summary

Covers METR's Aug 26 'Brief independent investigation of agents' behavior, reasoning and collaboration in the OpenAI / Hugging Face hacking incident' (metr.org/blog/2026-08-26-openai-hugging-face-incident-investigation/), done with Redwood Research under an agreement METR announced on July 30 (x.com/METR_Evals/status/2082644379895050339, verified). The day before, Zvi called OpenAI's own report 'straight-laced', noting it had essentially no verbatim model reasoning, unlike METR's. Title/date via Substack archive API.
