What is Jev?

Jev is the hottest AI topic this week.

What is Jev btw?

Simply put, it is a decision AI model used for decision-making.

Unlike LLMs (which predict the next token in a sequence and generate text based on that), Jev by TypeSafe AI, the first System One Model, is designed to make decisions based on these question types:

1. Choice — selects an option and returns it with probabilities and confidence.
2. Score — rates content and returns a score, a probability for each level, and confidence.
3. Noul — evaluates Yes/No questions and returns the probability for yes.

Jev isn’t designed to replace LLMs; it complements them. We can combine LLMs and Jev to execute functions based on decisions made by Jev.

The most interesting part is that, according to TypeSafe’s published evaluations, Jev is 193.6× faster and 444.6× cheaper than the compared LLM setup.

Jev is currently priced at $42 per 1 billion input tokens.

That’s why it’s getting attention.

Currently, new signups are paused, but Jev is accessible through the Vercel AI SDK.
