Local alternatives to Jev

Non-autoregressive System 1 decision engine. Typed choice, score and yes/no decisions over any text in a single forward pass, in 100+ languages, with a router that picks the right checkpoint per request.

Jev-like family of decision models built on top of Qwen3.5/3.8 you can train and run on your own

Semantic ifs from open models, on a 3090 at home. Independent; not affiliated with Jev or TypeSafe.

A nano replica of Jev: parallel decisions, dynamic candidates, and an end-to-end training pipeline.

jevos is an open-source alternative to Jev for yes/no decisions that runs on your laptop.

A family of System One-style models fine-tuned from Qwen3.5, designed for one-pass typed decisions with calibrated probabilities.

Run open decision models locally: pull and serve Laya, decider, NLI and GLiClass behind a TypeSafe-compatible API. Ollama for decision models.

Turn any LLM into a Jev-style decision model: typed decisions, real probabilities, no training. (continue updating, welcome any issue and PR request)
