Simon Willison released llm-typesafe 0.1a0, a plugin for his LLM CLI tool that adds support for TypeSafe AI's Jev model. The plugin enables structured output queries including yes/no (noul), choice selection, and scoring with predefined criteria.
Background
TypeSafe AI recently introduced Jev, a 'Decision Model' (System One) designed for structured, deterministic outputs rather than generative text. This aligns with growing industry interest in reliable LLM output formats.
