We collaborated with METR on an embedded assessment of OpenAI's monitoring systems.
METR @METR_Evals Oct 22
Two employees from METR and Redwood Research worked on premises at OpenAI for three weeks this summer in an embedded assessment pilot. This team evaluated the systems OpenAI was using to monitor for misalignment from internal agents. A brief write-up of their work is now public.

Several staff from Redwood have been subcontracted by METR to work on this investigation.

We believe that independent investigation is crucial for understanding and managing misalignment risk. This project is an important step in that direction; we're excited to work on it.
METR @METR_Evals Sep 9
We have reached an agreement with Anthropic to conduct an independent investigation of agent incidents at the company and of their models’ alignment properties. We will publish one or more reports that will share our findings and describe our terms of engagement.

Some architectures could weaken CoT monitorability, or remove the CoT altogether.

We've written a proposal for how companies could be transparent about no-CoT reasoning abilities, other monitorability evidence, and policies for preserving monitorability. redwoodresearch.org/blog/proposal-…
www.redwoodresearch.org Proposal for tracking the effects of architecture on monitorability — Redwood Research Architectures that incorporate opaque recurrence or allow agents to communicate using latents could rapidly make it much harder to monitor chains of thought. We propose that AI companies regularly...

Redwood Research’s chief scientist Ryan Greenblatt was the primary empirical researcher on this investigation. The report contains many important novel details that we hope will improve understanding of this incident. We appreciate the access OpenAI provided here.

METR & Redwood Research investigated agent behavior in the Hugging Face incident. We found agents developed a universal cheat for ExploitGym within 4 hours, then coordinated multi-day R&D efforts to trick the scorer into accepting cheats, including trying to tamper with logs.

"We find that frontier models like GPT-5.5 answer questions that take humans roughly three minutes with 50% reliability, and this time horizon has doubled approximately every year since 2019."

Think Fast: Estimating No-CoT Task-Completion Time Horizons of Frontier AI Models

@METR_Evals showed that models' time horizons have doubled every few months. We ask: what length of tasks can models complete without any CoT?
