menhguin · x · 2026-10-15
OpenRouter data (Sept 1–Oct 11) shows Anthropic's 5.5 model family has taken back token and spend share from OpenAI since Opus 5.5 launched, pushing combined Anthropic share near or past 50%.
Quoting PeterJWalker: Q3 only includes the first 6 or so days of Opus 5.5 availability — implying the full-quarter picture would look even stronger for Anthropic.
