TypeSafe AI Releases Jev: A Decision-Only Model That Returns Typed Probabilities Instead of Text
TypeSafe AI's Jev does what most LLMs won't: return structured probabilities instead of text. Early adopters are embedding it into Vercel and Netlify.

Why it matters
A decision-only model that outputs typed probabilities rather than natural language represents a shift in how AI handles deterministic tasks. Practitioners integrating classification or scoring workflows may find this more efficient than prompt-engineering traditional LLMs for structured output, but the narrow focus and lack of published benchmarks limit its immediate relevance.
