Jev Reaches 35% of Paying Vercel Teams in Two Weeks
Research citing Vercel data says TypeSafe AI's Jev was adopted by 35% of paying Vercel teams within two weeks, nearly double its nearest rival.
Research based on Vercel data indicates that Jev, a decision AI model from TypeSafe AI, became the fastest-spreading AI model by early adoption, according to digitaltoday.co.kr. The model reached 35% of teams paying for Vercel within two weeks of launch.
That figure is nearly double the adoption of Jev's nearest competitor, Sonnet 5.5. According to the Vercel data, no model had been adopted as fast in its first two weeks.
The data was collected through Vercel AI Gateway, an integrated API service similar to OpenRouter. Vercel also replaced GPT-6 Luna, which it had used for classifying harmful prompts, with Jev.
Open-source models accounted for over 70% of tokens passing through the Vercel gateway and nearly 25% of total spending.
