- What happened
- METR evaluated Claude Opus 5.5 and found it offers modest AI R&D acceleration over prior models, unlikely to fully automate research work.
- Why it matters
- Engineers at Anthropic and other AI labs should consider this when planning tool adoption and assessing whether AI can independently conduct research tasks.
- Watch out
- The evaluation relied partly on a separate confidential METR assessment whose supporting evidence and reasoning were not disclosed, limiting independent verification.
