Vercel data shows open-weight models surge to 62% token share
AccBalanced · x · 2026-08-23
As credible open-weight models offer material savings, greater data control, and reduced vendor lock-in, corporate fiduciary duties increasingly require directors to benchmark against open alternatives before approving proprietary model spend. Data from Vercel AI Gateway reveals a dramatic shift: open-weight model token share rose from 28.4% two months ago to 62% on August 22, while closed models dropped to 38%. This trend is likely just the beginning as enterprise adoption matures and tooling becomes more model-agnostic.
