What happened
OpenRouter data shows open-weight models handled 71.7% of tokens among its top 50 models on September 28, 2026, after peaking at 77.5% on July 20, 2026, up from 26.8% in October 2025.
Why it matters
The shift suggests a majority of tokens on this platform now run on models whose weights are publicly downloadable, a reversal from a year earlier when closed-weight models dominated.
