OneJev1.5-4B-GGUF

OneJev1.5-4B is a multimodal System One decision model fully fine-tuned from Qwen/Qwen3.5-4B on approximately 320,000 questions drawn from real agent runs, multimedia data, and public decision datasets. Designed for efficient and precise decision-making, it accepts diverse inputs—including text, screenshots, photos, and videos—alongside typed questions, returning calibrated probabilities for every option in a single forward pass. The model is highly competitive among sub-8B parameter models, achieving a leading score of 54.89 on the public portion of the Decision Index 0.3 benchmark, where it excelled particularly in Language Understanding and Tools & Automation. Accessible via the qev Python library and built around TypeSafe's System One API, OneJev1.5-4B serves as a powerful foundation for developing advanced GUI agents and complex multimodal decision workflows.
