Data indicates a significant shift in AI usage patterns toward lower-cost, non-frontier, and open-weight models. In August, open-weight models processed 56% of all tokens via Vercel’s AI Gateway, a substantial increase from 13% in April, despite representing only 14% of total spending. This trend aligns with a continuous decline in average price per token.

Further analysis of the OpenRouter platform shows that during the week of August 10, 84% of token volume was directed toward models not considered state-of-the-art. A small group of six models accounted for roughly 80% of volume, providing approximately 77% of frontier model performance at only 2.5% of the cost. Additionally, Chinese models have seen increased adoption, accounting for over 30% of US company token consumption on OpenRouter, up from approximately 4.5% in early 2025.

## Timeline

### 2026-10-13: OpenRouter users shift 84% of token volume to non-frontier AI models

OpenRouter data shows 84% of token volume is now driven by non-frontier AI models, as developers prioritize cost-effective, “good enough” performance over expensive state-of-the-art models.

### 2026-09-28: Open weight models process majority of AI tokens

Open weight AI models processed 56% of all tokens via Vercel’s AI Gateway in August, surpassing closed weight models for the first time as per the AI Gateway Production Index.
