Open one-pass typed-decision model with a dependency-free C99 runtime that also builds to a 66 KB WebAssembly module.

Local browser agent that picks each step's operation and element with a Jev-shaped model such as a fine-tuned Laya, no cloud needed.

Self-hosted PR review platform pairing an LLM narrative with a /v1/systemone decision engine for 6 rubric scores and 8 yes/no merge gates.

Free hosted Jev-style multimodal decision model API (about 20B active) that picks actions from images and options, aimed at robot control.

DuckDB extension adding decide_probability, decide_choice and decide_score SQL functions backed by Jev or local open decision models.

Runs the open Laya decision model entirely in a browser tab with WebGPU and ONNX Runtime Web: no server, no API key.

ComfyUI nodes that branch workflows on typed Choice, Yes/No and Score judgments from Laya, Jev or Cloudflare Clef.

ComfyUI nodes for Jev-style noul, choice and score decisions over images and text using a local imajev adapter on Qwen3.5.

Computer-use platform (Cua Spaces, Driver, Lume) with CUA-S1 small decision models and a preview jev-use example for bounded actions.

Docker service exposing local Laya, Von, a CLM head or hosted Jev through one TypeSafe-compatible HTTP and MCP endpoint.

Evaluation suite for decision models with 23,900 pinned rows across nine task families and three primitives, plus a leaderboard.

Converts open Jev reproductions (Laya, Kev, NanoJev, PlayJev) to INT8 ONNX for offline CPU decisions at about 15.6 ms per question.

Native Go runtime serving Gemma 4 12B as a Jev-like decision model with hand-tuned PTX kernels and no CGo or CUDA toolkit.

Go harness for System One models: hosted Jev, open Kev in-process via llama.cpp, and Cloudflare Clef, with typed helpers and a CLI.

Go gateway exposing the Jev /v1/systemone contract over ordinary LLM backends by reading single-token label logprobs.

Local agent workbench whose decision crate borrows the System One state/questions request shape, starting with Cloudflare's Clef.

llama.cpp-based C++ server that turns any LLM into a System One decision model, reading answers from next-token logits.

Runs Intern-Decision-0.8B on Apple Silicon behind a local /v1/systemone endpoint that accepts screenshots for agent decisions.

TypeScript library for one-line local decisions with open models (kev-0.6b, kev-4b, open-jev), no API keys or cloud.

Fork of the jev-chat Windows app adding a key-free local LAYA judgment backend and a DPI-aware screen capture fix.

MCP server exposing Jev-style decision models served locally by Ollama's /v1/systemone as classify, yes/no and score tools.

Router that uses Jev's cloud decisions today, logs every decision with probabilities, and distils a local routing model from your traffic.

Three open 4B decision models for English, Turkish and German that serve the Jev /v1/systemone API on a CPU in about 3 GB of RAM.
