What Jev is: AI as multiple choice, not essay writing

An ELI5 explanation of Jev: it doesn't chat, it makes decisions software can act on, such as spam or not, which tool an agent should use, or whether a human is needed, and is claimed to be about 200x faster and 400x cheaper than frontier LLMs in TypeSafe's own workflow benchmarks.

WTF is Jev by @typesafeai? Here’s the tl;dr ELI5: Think AI multiple choice, not AI essay writing. It doesn’t chat. It makes decisions your software can act on: “Spam or not?” “Which tool should this agent use?” “Does this need a human?” The exciting part: roughly 200x faster and 400x cheaper than frontier LLMs in TypeSafe’s own workflow benchmarks, with responses in a fraction of a second. Why that’s powerful: imagine an app or agent making hundreds of little judgment calls without hundreds of expensive, slow conversations with an LLM. Keep the big model for the hard thinking and writing. Use Jev for the rapid-fire decisions in between. Excited to dig in.
