Jev Becomes Vercel's Fastest-Adopted AI Model in Two Weeks
Vercel reported that Jev, an AI decision model developed by TypeSafe AI, has become the fastest-adoption model within its first two weeks of launch. According to data published on November 4, 35% of paid Vercel teams were using Jev in just over a fortnight since its limited release on September 15. The adoption rate is nearly double that of Sonnet 5.5, the second most popular model at Vercel's AI gateway. Jev’s design as a lightweight tool for selecting from predetermined outputs allows it to run faster and cheaper than alternatives like Sonnet, making it ideal for data classification tasks. This has led to significant interest in Jev, prompting responses from competitors such as OpenAI and Amazon. The model is already being used by Vercel itself to replace GPT-6 Luna for classifying harmful commands. The report also highlights the growing momentum of open-source models through Vercel’s gateway, which now account for over 70% of tokens processed and nearly a quarter of total spending. Despite this shift toward open source, spending on frontier AI labs has increased tenfold, suggesting that these two approaches may be complementary rather than competitive in the market.
