🔥🔥 Papers, open reproductions and independent evaluations behind System One models and Jev.
Typed decisions with TypeSafe's Jev, the first System One model
Native MLX runtime for Laya typed decision models — 7–14 ms short decisions on M3 Max. No text generation, PyTorch, or cloud API.
Open-source alternative to TypeSafe's Jev: a System One style model layer that gives typed, calibrated decisions from any open-weights LLM in one forward pass (HF + vLLM), with honest benchmarks
Fast Rust CLI for TypeSafe Jev: typed decisions, offline linting before you pay
Curated catalog of System One / Decision Models — contributions for modelsystem.one
Open-source projects that provably call Jev, TypeSafe AI's System One model. Every entry links to the line of code that proves it. Refreshed daily.
Local Laya typed decisions on Apple Core ML and Neural Engine. Validated ports, ~5 ms short decisions on M3 Max, reproducible speed and energy benchmarks.
Optional TypeSafe AI/Jev advisory decision evidence for Agent-Workflow, without transferring lifecycle authority from deterministic orchestration.
Open reproduction of TypeSafe Jev: a 150M typed decision engine (noul/choice/score in one non-autoregressive pass, calibrated confidence). 0.697 vs Jev's 0.727, 2.5x better calibrated, 4x faster, free. Trains on a Colab T4 in 30 min.
