Newly released open decision models and open-source projects built with them, as tracked in the DecisionEval directory.https://decisioneval.dev/https://decisioneval.dev/built-with/undrgrnd-labs/hunch/https://decisioneval.dev/built-with/undrgrnd-labs/hunch/hunch is a "System One"-style server that answers questions (e.g. "did this tool call fail?" or "does this output contain a prompt injection?"), on CPUs in milliseconds. It learns and then graduates from a slower, more expensive "teacher" model and keeps itself up-to-date by checking in, even after it graduates.Wed, 21 Oct 2026 00:00:00 GMThttps://decisioneval.dev/built-with/jwuthri-cloud/selfjev/https://decisioneval.dev/built-with/jwuthri-cloud/selfjev/Website   ·   Get started   ·   PyPI   ·   Download the model   ·   Evaluation dataset   ·   API reference   ·   Research notebookWed, 21 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/archai-jev-games-1-5b-v2/https://decisioneval.dev/models/archai-jev-games-1-5b-v2/archai-jev-qwen-1.5b fine-tuned to return typed decisions, 1.5B parameters.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/kodoom/https://decisioneval.dev/models/kodoom/laya-multilingual fine-tuned to return typed decisions.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/laya-coreml-adaptive-fp16/https://decisioneval.dev/models/laya-coreml-adaptive-fp16/A Core ML build of laya, for running typed decisions on on-device Apple runtimes instead of a hosted API.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/laya-coreml-adaptive-fp32/https://decisioneval.dev/models/laya-coreml-adaptive-fp32/A Core ML build of laya, for running typed decisions on on-device Apple runtimes instead of a hosted API.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/laya-multilingual-coreml-adaptive-fp16/https://decisioneval.dev/models/laya-multilingual-coreml-adaptive-fp16/A Core ML build of laya-multilingual, for running typed decisions on on-device Apple runtimes instead of a hosted API.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/laya-multilingual-coreml-adaptive-fp32/https://decisioneval.dev/models/laya-multilingual-coreml-adaptive-fp32/A Core ML build of laya-multilingual, for running typed decisions on on-device Apple runtimes instead of a hosted API.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/laya-typed-decisions-coreml-adaptive-fp16/https://decisioneval.dev/models/laya-typed-decisions-coreml-adaptive-fp16/A Core ML build of laya-typed-decisions, for running typed decisions on on-device Apple runtimes instead of a hosted API.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/laya-typed-decisions-coreml-adaptive-fp32/https://decisioneval.dev/models/laya-typed-decisions-coreml-adaptive-fp32/A Core ML build of laya-typed-decisions, for running typed decisions on on-device Apple runtimes instead of a hosted API.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/sn92-df-v8/https://decisioneval.dev/models/sn92-df-v8/JevK5-9B fine-tuned to return typed decisions, 9B parameters.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/sn92-df-v9/https://decisioneval.dev/models/sn92-df-v9/JevK5-9B fine-tuned to return typed decisions, 9B parameters.Tue, 20 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/elythros-decider-0-6b-gguf/https://decisioneval.dev/models/elythros-decider-0-6b-gguf/A GGUF build of elythros-decider-0.6b, for running typed decisions on llama.cpp instead of a hosted API.Mon, 19 Oct 2026 00:00:00 GMThttps://decisioneval.dev/models/voice-decisions-laya-v4/https://decisioneval.dev/models/voice-decisions-laya-v4/laya fine-tuned to return typed decisions, 421M parameters.Mon, 19 Oct 2026 00:00:00 GMThttps://decisioneval.dev/built-with/mars-tw/jev-trading-command-center/https://decisioneval.dev/built-with/mars-tw/jev-trading-command-center/A paper-trading research application with TypeSafe Jev decisions, an animated 3D command center, model pets, a responsive ten-timeframe research panel, an owner-authenticated remote view, and a local offline demo.
