- Jev hit 35% adoption among Vercel paid teams within two weeks of its September 15 limited release, the fastest two-week adoption of any model Vercel has tracked.
- TypeSafe AI's Jev reached nearly double the reach of the second-most-popular model, Sonnet 5.5, on Vercel's AI gateway.
- Jev is designed as a lightweight decision-classification tool that runs cheaper and faster than alternatives like Sonnet — a design that has inspired competing offerings from OpenAI and Amazon.
- Vercel itself was an early adopter, replacing GPT-6 Luna with Jev for classifying harmful commands.
- The dataset has a built-in caveat: Vercel's AI gateway likely undercounts major labs like OpenAI and Anthropic that route through their own APIs rather than third-party gateways.
- Open source models now account for more than 70% of tokens processed through Vercel's gateway and nearly 25% of total spend, while spending on frontier labs grew tenfold even as their share shrank — evidence the two tiers may be complementary rather than competitive.
Why it matters: TypeSafe AI, a smaller player, secured adoption from 35% of Vercel paid teams in two weeks with a niche decision-classification model that runs cheaper than Sonnet, prompting competing offerings from OpenAI and Amazon. Vercel's data shows frontier and open-source models grew tenfold in tandem, suggesting the two tiers are expanding the pie rather than purely fighting for share.
