Type-safe Java 21 client for the TypeSafe AI Jev (System One) decision API
OpenJev: an independent Jev-inspired System One decision API based on TypeSafe.ai concepts. Choice, score and noul primitives, local mock server, Python and TypeScript SDKs. Real inference planned; not affiliated with TypeSafe AI.
Zig SDK for TypeSafe AI's Jev decision API. Typed classification, scoring and yes/no probabilities with bounded buffers, retries and deadlines.
Experimental: DSPy-powered, type-safe decision API with confidence scores — aiming for a fine-tuned model-to-decision pipeline
Catch an AI agent stuck in a loop — Jev grades each step progress/repeating/stuck/escalate. Single-file, no build. Use free: jevtypesafeai.com/tools/agent-loop-detector
Route each task to the one tool an agent should call, with Jev — with confidence. Single-file, no build. Use free: jevtypesafeai.com/tools/jev-skill-router
Type words that fit a clue; Jev scores each and your car races ahead. Single-file, no build. Play free: jevtypesafeai.com/games/jev-semantic-racer
Fight beside a Jev-controlled AI teammate that decides its own move (attack/defend/follow/retreat) each round. Single-file, no build. Play free: jevtypesafeai.com/games/jev-companion-arena
Open self-hosted System One decision API (Jev wire-compatible) + agent skill — 87.9% JevBench, beats Jev on accuracy and score
Curated guide to decision engines, rules APIs, authorization, MCP interfaces, workflow execution and decision evidence. Maintained by Decide.
You drive Pac-Man; Jev — TypeSafe AI's decision model — drives the ghosts hunting you, one real typed decision per turn. Single-file, no build. Play free: jevtypesafeai.com/games/jev-pacman
You vs Jev: race across Wikipedia by clicking links; Jev picks the closest of dozens each hop, one real typed decision, no hallucination. Single-file, no build. Play free: jevtypesafeai.com/games/jev-wikiracer
Capability-aware, vendor-neutral decision runtime for Jev and local engines
Mac/Win Electron app for testing Jev, System One, and similar decision APIs inc. local models like Clef with Ollama. Build requests using forms or JSON and explore structured responses. Made with NativePHP.
Run fast, calibrated, typed decisions on open System One models with a Jev-compatible API.
