High-Frequency & Simulation MIT E1 · source linked

Laya (open source, local) vs TypeSafe Jev (API): two AI models race in Snake and fight in a Mortal-Kombat-style arena. Every move is a real model decision.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

Routing & Cost Optimization MIT E2 · source reviewed

Loki optionally adds Jev typed-judgment tools and routes a new session to a model within the selected gateway.

JEV · Decision point

Assesses the first task’s capability needs; local policy chooses a same-gateway model and keeps the route sticky.

Makes model routing explicit while retaining the selected route for the session.

Security & Guardrails MIT E1 · source linked

Everything you need to run TypeSafe's Jev with Claude Code: a tool-call guard, tier guard, file search, browser agent, review, belay, compaction and installers.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

Context GC & Filter MIT E2 · source reviewed

A small typed decision layer for agent integrations, with check, pick and rate primitives and explicit escalation to a generative model.

JEV · Decision point

The application dispatches suitable bounded decisions to the backend; the TypeSafe adapter converts native requests and parses answers, while escalation returns unresolved work to the caller.

Exposes the handoff between typed judgments and text generation without claiming that either component owns the whole agent.

CLI & Pipelines MIT E1 · source linked

grep for what code does, not what it's called. Semantic code search powered by TypeSafe Jev.

JEV · Decision point

Measured (2026-09-19, jev-1.13.0): a 896-chunk TypeScript `src/` tree in 1.8 s for $0.010 (240k input tokens); repeat query 0 s from cache.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

SDK & Decision Frameworks MIT E2 · source reviewed

A local decision-model toolkit with candidate readouts, shared-prefix inference and development-set temperature fitting for Choice, Boolean and Score outputs; no output-token decoding is required.

JEV · Decision point

Encodes state and question-specific candidates, then scores them through decision heads. Reuse mode requires explicit backbone support; calibrated temperatures are stored in checkpoints.

Provides training, calibration and evaluation tooling for local decision experiments. A new application still needs held-out labels and a coverage/error assessment.

Context GC & Filter MIT E2 · source reviewed

Context-pruning proxy for Claude Code and Codex, employing Jev to prune redundant history while keeping tool protocols intact.

JEV · Decision point

Intercepts request payloads and uses Jev to score historical messages, discarding outdated tool noise before forwarding to upstream LLMs.

Decreases input token counts and time-to-first-token while preserving protocol compliance with client tool calling standards.

A Jev harness for StarCraft shareware’s Strongarm mission, pausing the game during state reads and inference.

JEV · Decision point

Selects commands from structured game state and executes them with mouse and keyboard input.

The author provides a victory recording and verification report; this is a bounded mission experiment, not a real-time competitive benchmark.
