Anthropic reports Claude leads 26% of its measured AI R&D work
Anthropic's R&D Automation Index reports that as of August 2026 Claude leads 26% of measured AI R&D work from high-level prompts under human supervision, while more than 90% is at least human-AI collaborative. Anthropic explicitly reports no measured subset at full autonomy and notes methodological limitations including use of its own models as judges.
