## Summary

Data published by Vercel shows that Jev was used by 35% of paid teams within two weeks of its limited release on September 15, nearly double the reach of the second-most popular model, Sonnet 5.5. Vercel says this was the fastest adoption any model has seen in that period; Jev is developed by TypeSafe AI and was designed to choose among a few predetermined outputs at lower cost and higher speed. Vercel uses it to classify harmful commands, replacing GPT-6 Luna.

The metric comes from Vercel’s AI gateway, a limited view that may undercount companies such as OpenAI and Anthropic, which operate their own APIs. Open-source models account for more than 70% of tokens processed through the gateway and nearly 25% of spending, while spending on frontier labs grew tenfold, according to Vercel’s data.

## Why it matters (editorial interpretation)

Vercel’s measured adoption suggests that specialized models for constrained decisions may gain ground in real applications, especially when cost and speed matter. Because the gateway offers a limited view and Vercel itself uses Jev to classify harmful commands, the data does not support generalizing the result to the entire market.
