To Jev or not to Jev? That is the question.

​If you've dropped everything last week to try Jev, this is for you. Or well.. If you really wanted to but couldn't, this is especially for you.

TypeSafe's own evals claimed 193.6x faster and 444.6x cheaper than comparable LLMs. Plenty of people agreed! It became the fastest-adopted model in Vercel's AI Gateway history within 3 days. But we've also seen the "just a classifier" dismissal, and an independent benchmark where a year-old Claude Haiku beat it outright.

So is it brilliant or overhyped? Well! It doesn't matter. Trying it for your own use case is the only way to know.

In this webinar, we'll pick a couple of real-world agent use cases and see how Jev fares against GPT-5.4-mini, Claude Haiku 4.5 and Gemini 3.5 Flash. We'll cover how to set up the experiment, run evaluations across models, the choices we made and why, and what we learned.
