Claude now leads 26% of Anthropic's model R&D tasks; simple extrapolation puts it near 68% now

peterwildeford cites Anthropic's R&D Automation Index: the share of model R&D tasks where Claude 'leads' (AL4 on Epoch AI's automation scale) grew from 1% in March 2026 to 26% by August. A simple trend extrapolation suggests it should now be around 68%.

He calls the number important and urges Anthropic to update the data — and OpenAI to publish comparable figures. The chart shows Anthropic's internal model R&D shifting rapidly from human-led to AI-led over the past year.
