Discover what people build with Jev
The curated map of SDKs, integrations, demos, and apps on TypeSafe System One. Watch real builder clips, skim honest listings, and open docs when you are ready to wire something up.
What is Jev?
Structured decisions, not chat essays
“Ask Choice, Score, or Noul. Get probabilities your code can threshold. Skip the pep talk.”
Jev is TypeSafe's System One model: parallel typed questions in, calibrated answers out. Fast, cheap, and allergic to writing paragraphs when a boolean would do.
Open models such as Laya sit beside the hosted API. Read Jev alternatives compared for the ranked list, or Liquid d1 vs Jev for the small multimodal checkpoint.
Setup guides: Jev with Hermes Agent and GitHub Copilot Agent Mode + Jev.

decide() in TanStack AI
TanStack ships decide() for typed choices, scores, and booleans so your agent loop stops faking it as a chatbot. They call the moment jevolution; we call it one less regex on model prose.

FAQ
Quick answers
The TL;DR on Jev and this site. More depth on Learn.
- What is Jev?
- Jev is TypeSafe AI's System One decision model for software. You send structured state and typed questions (Choice, Score, or Noul). The API returns discrete answers with probabilities and confidence. Your code applies thresholds and runs side effects.
- How is Jev different from an LLM?
- LLMs generate open-ended text. Jev answers fixed questions with explicit probability mass over options. That makes routing, moderation, and safety gates easier than parsing YES or NO from chat output.
- How do I try Jev on Vercel AI Gateway?
- Use model id typesafe-ai/jev through Vercel AI Gateway with the AI SDK, including experimental_evaluate flows. See Vercel's gateway docs and the eve agent framework for TypeScript examples.
- What is this directory?
- Jev Directory at jev.aitools.fyi is an independent index of SDKs, integrations, Jev MCP servers, demos, and apps. The explore index lists the full public catalog; only stronger listings get on-site detail pages under paths like /sdks/ and /tools/. Published by aitools.fyi. Not affiliated with TypeSafe AI unless a listing is official.
- What is the Jev AI website?
- TypeSafe AI hosts product docs and the playground at docs.typesafe.ai and jev.works. This site, jev.aitools.fyi, is a community directory of tools, SDKs, benchmarks, and guides that use System One Jev. Start on Learn for primers, then Explore for listings.
