GoKawiilTypeSafe AI's Jev model hits 35% adoption among Vercel's paid teams in two weeks
Vercel reported that its Jev decision model, released in limited form on September 15 by TypeSafe AI, reached 35% of paid teams within two weeks — nearly double the reach of the next most popular model, Sonnet 5.5. The data, drawn from Vercel's AI gateway, also shows open source models now handle over 70% of tokens processed but only about 25% of total spend, while frontier-lab spending has grown tenfold.
GoKawiil's interpretation of the reporting above, not reported fact.
The adoption figures offer the first concrete usage data behind the buzz around Jev's lightweight, low-cost approach to classification tasks, which has already prompted competing products from OpenAI and Amazon. Because Vercel's gateway likely undercounts labs like OpenAI and Anthropic that run their own APIs, the numbers may understate those rivals' true usage even as they confirm Jev's rapid uptake. The combination of rising open-source volume and growing frontier-model spend suggests, per Vercel's data, that cheaper specialized models and expensive frontier models could be complementing rather than replacing each other.
- Jev reached 35% of Vercel's paid teams within two weeks, the fastest adoption Vercel has recorded for any model.
- Open source models now account for over 70% of tokens processed through Vercel's gateway but just 25% of spend.
- Frontier lab spending has grown tenfold even as its market share shrinks, hinting at coexistence between frontier and open source models.
