  "content": "METR, after an eleven-week high-access assessment, estimated that roughly 80% of [[claim:76cf8c84-c5ec-4277-9539-38e03f8e1a07|Anthropic's acceleration as of October 2026 is attributable to AI assistance]], ruled out faster training-compute scaling as the cause, and judged that the other factors it examined would not explain a sustained acceleration. Staff interviews centred on about a twofold AI speedup. METR's judgment is reliable on this question, and AI's share grew over time. So AI assistance plausibly accounts for most of the acceleration over the whole period.",

  "content": "[[claim:c175bbcd-10be-4d49-89a0-61fe742c0d29|Non-AI factors likely drove the late-2025 acceleration]], and Anthropic's pre-2025 AECI growth rate was below the industry frontier, so part of the measured acceleration may be catch-up. METR itself expects the cumulative AI share since October 2025 to be lower than the instantaneous October 2026 share. The claim covers the whole period, so these early non-AI contributions may leave AI's cumulative share short of a majority.",
