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.

Independent mathematicians present GPT-6 Astra proof of the Erdős–Sós conjecture
Oliver Riordan and Alex Scott state that the Erdős–Sós conjecture was recently proved by GPT-6 Astra using a surprising argument and publish a simplified version, also determining extremal graphs and proving a related conjecture. David R. Wood separately publishes an exposition of the proof, likewise attributing its discovery to GPT-6 Astra. The multiple expert rewrites provide unusually strong independent validation of the AI-origin claim.

Reuters independently corroborated the September 8 launch and its cross-app action scope. Early reporting also notes security and reliability concerns, so the launch is treated as deployment evidence rather than proof of robust general autonomy.
