Calibrated 151M Non-Autoregressive Decision Engine beating TypeSafe Jev & Laya on LocalLLaMA/typed-decisions (77.10% acc, 0.0636 Brier, 0.0144 ECE)

🚀🚀 A 0.8B JEV-like multimodal model playing GUI games directly from raw pixels.

Super fast Jev like server, model agnostic, working with any OpenAI compatible endpoint

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.

Local multimodal decisions on your Mac. Jev-compatible typed probabilities with Qwen, llama.cpp and Metal.

Openjev experiments

MCP server exposing TypeSafe's Jev through the public OpenJEV API. Send one shared context and several independent questions; get typed judgments and probabilities back — choice, score, or yes/no — not prose. Built for DeepSeek Harness; runs unchanged in any MCP client.

Sub-10ms calibrated semantic decision engine & runtime for edge, embodied control, agent simulation, and typed dynamic workflows.

Add as much tabular data as you want to Jev models using adaptive ensembles that learn to query only the rows and columns needed.

IntentFlags — semantic feature flags for websites, powered by Jev. Infers what a visitor is trying to do and hands it to your React code as a flag.

When and Where Actually to use Jev in your code base.

A curated list of decision models similar to, alternatives to, or reimplementations of Jev (TypeSafe AI's System One model for typed decisions).

A pre-execution gate for AI agent actions, powered by TypeSafe's Jev (System One) model.

Jev 决策的 Record / Replay 工具：CLI + 本地代理 + JSON 磁带，回放彻底离线。

Open-source Jev harness for TypeSafe, OpenJev, LocalJev, Ollama, vLLM, LM Studio, llama.cpp. Typed decisions, calibration, verification, abstention, CI gates.

Claude Code plugin that scores how well you prompt a coding agent, and shows whether your habits are improving. Runs on TypeSafe's Jev model. Zero added latency.
