Decision models take 26% of requests; Anthropic now wins new teams 2:1

Vercel AI Gateway’s November 2026 Production Index, based on anonymized aggregate traffic through October, reports rapid changes in production AI adoption across more than 100 trillion monthly tokens. Decision models, which classify or select rather than generate text, reached 26% of requests within weeks of their introduction but represented only 0.53% of spending because of their low cost, with adoption especially high among the largest users. Voice-model adoption rose from 4% of paid teams in July to 11% in October as teams increasingly added speech-to-text and text-to-speech capabilities to existing AI applications. Anthropic and OpenAI reached nearly equal shares of paid teams, although Anthropic attracted almost twice as many new teams in October, while OpenAI increased its portion of gateway spending from roughly 9% to nearly 15% since December. Model selection has become highly fluid, with over half of language-model requests going to versions under 60 days old and many teams quickly shifting to newer releases or competing labs. The report also notes record adoption of image and video models, strong usage of Anthropic’s models, and leading spend positions for Opus 5.5 in language, OpenAI’s GPT-Image-2.5 Sunburst in image generation, and ByteDance’s Seedance 2.5 in video.
