Frequently asked questions

More in this category

• Mapika/deciderA family of System One-style models fine-tuned from Qwen3.5, designed for one-pass typed decisions with calibrated probabilities.
• wfzyx/vonThe open-source System One decision model. Sub-15ms, non-autoregressive, local drop-in alternative to TypeSafe Jev.
• YannQi/R-4BA 4B open decision model (Reflex-4b): benchmarked at 2-3x faster than Jev with roughly 5% lower accuracy, Apache 2.0.
• kshetrajna12/reflexA small open decision model: state + typed questions → calibrated probabilities, re-created on Qwen3.5.
• ikermoel/open-alternative-jevOpen-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
• Mapika/decider-2bA 2B open decision model (Decider-2b): benchmarked at ~10x faster than Jev, fully local, roughly 5% lower accuracy.
• r-ms/mini-jevmini-Jev: what a Jev-style typed-decision interface looks like on a frozen Qwen3-4B — read the option letter's logits instead of generating JSON. Preregistered experiment, results, teaching bench.
• zhengxuyu/litjevTurn any off-the-shelf LLM into a Jev -like decision layer
