Jev surpasses previous records as vercel's most rapidly adopted AI model

Vercel's data reveals that Jev, a decision-making AI model, has achieved the fastest adoption rate in its first two weeks, surpassing previous records. Launched on September 15, Jev has been adopted by 35% of paid teams within two weeks, nearly double the reach of Sonnet 5.5, the second most popular model. This rapid adoption has sparked competition from OpenAI and Amazon, though hard data on its success was previously scarce. Vercel's AI gateway, a unified API service, shows Jev's popularity translating into real usage, with the company itself adopting Jev to replace GPT-6 Luna for classifying harmful commands. The data also highlights the growing influence of open-source models, which now account for over 70% of tokens processed through Vercel's gateway and nearly 25% of total spend. Despite open-source models capturing a larger market share, spending on frontier labs has increased tenfold, suggesting potential complementarity between frontier models and open-source alternatives. Additional news includes Tesla's reveal of a SpaceX-powered Roadster, the FBI's arrest of an OpenAI employee, and Bumble's $1.3B acquisition deal.
