About this project

TypeSafe AI is a San Francisco AI lab building System One models — a class of model trained to return typed, calibrated decisions for software rather than generated text. Its flagship and first System One model, Jev, is served by a single HTTP endpoint: POST /v1/systemone takes a state plus a map of typed questions and returns one structured answer per question, each carrying probabilities and (for Choice and Score) a confidence value.

Quoted from the project's README. Read the full README.

Highlights

  • Describes POST /v1/systemone taking state plus typed questions and returning per-question probabilities.
  • Collects OpenAPI, overlays, A2A card, MCP server, skills, llms.txt, well-known probes, and SDK notes.
  • States Kin Score and readiness rate public artifacts only, not safety, security, or quality audits.
  • Contains text and machine-readable descriptions only; warns hostile download links are not from them.
