An Anthropic risk assessment from AI safety organization METR is out.
Among other findings, METR says that Anthropic is “likely improving the capabilities of their models on well-specified tasks at around twice the rate they did between March 2024 and October 2025.” That acceleration is “likely” thanks to Anthropic’s extensive use of AI to do R&D.

TL;DR
- METR, an AI safety organization, has published a risk assessment on Anthropic.
- The assessment indicates Anthropic is likely improving AI model capabilities at double the previous rate.
- This acceleration is attributed to Anthropic's extensive use of AI for R&D.
- METR communicated with Anthropic regarding the report, which was released publicly on November 3rd.
- The release coincides with Anthropic CEO Dario Amodei's essay on pacing AI development.
