A plugin that lets you ask Jev yes-or-no, pick-one and score questions from Simon Willison's LLM command-line tool.
@simonwAdds TypeSafe's classification and scoring models, including Jev, to LLM, the popular command-line tool for working with language models. Once installed, Jev is available under the short name jev.
Install it with one LLM command and set your TypeSafe key. The author's blog post walks through what decision models like Jev are and how the plugin uses them.
Turns any open-weight LLM into a Jev-style decision model, reading typed choices and calibrated probabilities straight from its logits or hidden states.
