Cheap, Fast Jev Becomes the Fastest-Adopted AI Model on Vercel

    Jev has become the fastest-adopted artificial intelligence model to date on the Vercel platform. The model had a limited release on September 15 and rapidly gained popularity in its first 2 weeks. By the end of that period, it was being used by 35% of paid teams. Jev was adopted approximately 2 times as widely as Sonnet 5.5, the second most popular choice.    Jev is a simple decision model that selects from several predefined responses. Because the response options are limited, it operates more cheaply and quickly than alternatives such as Sonnet. The model can categorize large volumes of data in a short time and is primarily intended for tasks that require a simple choice.    This approach attracted considerable interest after it was announced. OpenAI and Amazon have also developed similar solutions. However, until now, there have been few concrete figures showing that this interest has translated into actual use. Vercel was one of the early companies to adopt the model. The platform replaced the GPT-6 Luna model previously used to group malicious commands with Jev.    The statistics are based on usage within the Vercel AI Gateway service. This service, which works like OpenRouter, makes it easier for applications to connect to various artificial intelligence models through a single API, or common connection system. However, the figures do not cover the entire market. Major companies such as OpenAI and Anthropic have their own API services. As a result, the use of their models may appear lower in these statistics than it actually is.    Open-source models account for more than 70% of the tokens processed through Vercel’s gateway. A token is a unit of text processed by artificial intelligence. Approximately 25% of total spending goes to these models. Although spending on laboratories developing advanced models has increased 10 times, their share of total spending has declined. The figures show that open models and advanced commercial models are being used in parallel in the market.
