Multiple choice, not essay writing: Jev as an ELI5
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
Why it is here
An explainer aimed at people who have never heard of the model, summed up in the line worth keeping: think multiple choice, not essay writing. Useful as the single link to send somebody who asks what this is — and the 200x speed claim in it is the author's, not a measurement.
