Typesafe’s Jev becomes fastest-adopted model on Vercel gateway
Vercel data shows that Jev, a lightweight decision model from Typesafe AI released in limited form on Sept. 15, was used by 35% of paid teams within two weeks—nearly double the reach of the next model, Sonnet 5.5. Vercel, which used Jev to replace GPT-6 Luna for some harmful-command classification, cautions its gateway data may undercount providers that run their own APIs; the report also notes open-source models now account for over 70% of tokens on Vercel and about 25% of spend while frontier-lab spending has grown tenfold.
