summary: "An analysis by independent evaluator METR rules out increased compute as the primary driver of Anthropic's recent research speedup. METR estimated that benchmark scores on Anthropic's capability index have grown 1.9x faster since October 2025, though a separate analysis showed that progress per dollar fell 63% between the first halves of 2025 and 2026."

## Summary

An analysis by independent evaluator METR rules out increased compute as the primary driver of Anthropic's recent research speedup\. METR estimated that benchmark scores on Anthropic's capability index have grown 1\.9x faster since October 2025, though a separate analysis showed that progress per dollar fell 63% between the first halves of 2025 and 2026\.
