  • Open, local Jev-style server on llama.cpp that returns typed decisions from a fine-tuned Spark-X2.5-4B without generating tokens.

    ModelbetaPython
  • Local Jev-compatible /v1/systemone server that reads typed answers from the logits of any MLX or OpenAI-compatible model, no training.

    LibrarybetaPython
  • Standard Thinking's Apache-2.0 3B and 8B decision models on Ministral 3 that score bounded answers via /v1/systemone, with vision.

    ServicebetaPython
  • Rust server on candle that serves open decision models like Laya and Clef behind a System One-compatible API with dynamic batching.

    ServicebetaRust
  • Runs Laya System 1 models on a Mac's GPU in Rust with custom Metal kernels, serving the same /v1/systemone API as laya serve.

    ModelbetaRust
  • Open 596M and 4B decision models that answer Choice, Score and Noul in one pass locally, with calibrated confidence for escalation.

    ModelbetaPython
  • Apache-2.0 395M ModernBERT System One model serving calibrated Choice, Noul and Score locally as a drop-in /v1/systemone replacement.

    ServicebetaPython, TypeScript
  • Apache-2.0 ModernBERT decision model answering Noul, Choice, Score and multi-label questions, with a local Jev-compatible server.

    ServicebetaPython
  • OpenJevPro: typed Choice/Noul/Score API over open LLMs, Laya or Jev with order-invariant scoring and a System 2-to-1 distillation flywheel.

    ServiceprototypePython
  • Claude Code plugin where a local decision model (Laya, or Jev) flags profane or abusive prompts and an instruct model rewrites them.
