Evaluation & Observability MIT E2 · source reviewed

A word-level generation experiment that asks Jev to select words or verify locally drafted continuations.

JEV · Decision point

Choice selects the next word; Noul evaluates candidate chunks and stopping conditions.

Exposes the limitations of using a decision model as a text generator.

SDK & Decision Frameworks MIT E1 · source linked

Independent calibration test of TypeSafe's Jev on a task it cannot have seen: 900 rule-generated support tickets (choice / score / boolean) plus 3 public benchmarks via Vercel AI Gateway. Raw responses, ECE with noise floor, temperature refit, per-type sign of miscalibration. Reproducible for ~$0.06.

Decision Tools MIT E1 · source linked

Pokemon Red on PyBoy where Python owns the route and the arithmetic, and Jev chooses only among legal actions at actual branches.

JEV · Decision point

A Choice over legal actions at each branch; battle turns also ask Noul faints_this_turn and should_flee; failures take the code default.

The model only picks among code-proven legal moves; a failed call never loosens the script.

**Learn Jev end to end** is a free, hands-on course. In 12 short notebooks you go from *"what is Jev?"* to building **13 real AI tools** with it: an email triage job, a scam-text detector, a code vulnerability hunter, an agent safety guard and more. You need **one API key**, and running the whole course costs **less than $0.20**.

Routing & Cost Optimization MIT E2 · source reviewed

Calibrated tool selection and schema pruning for AI agents. Dual-engine: zero-dependency offline TurboQuant or TypeSafe System One (Jev). Prunes candidate MCP tools and schemas down to the relevant set before calling LLMs to eliminate hallucinations and save tokens.

JEV · Decision point

Jev makes atomic decisions on tool selection (`choice`) and whether user intent requires open-ended creative generation (`noul`), with calibrated probability distributions.
