Model overview
What this model is for
Decision-2.0-Nox-4B is a text-only model designed for typed decisions rather than conversational prose generation. It answers caller-defined choice, yes/no, and score questions by returning probability distributions, making it potentially useful for semantic routing, classification, confidence-aware branching, and other applications that need structured decision outputs. Its listed use case is typed-decisions. The model is identified as a 4B-parameter member of vLLM Semantic Router’s Decision 2.0 family and is described as Apache-2.0 licensed, which may be suitable for applications requiring a permissive open-source license, subject to reviewing the repository’s complete license and usage terms. The available source does not disclose a context window, inference-speed benchmark, pricing, evaluation results, or deployment requirements. It also does not document broader capabilities such as coding, tool calling, vision, audio, or image generation, so it should not be selected for those needs without additional evidence. The Hugging Face page is the cited source, but the supplied page content does not expose a publication or update date; source freshness therefore cannot be independently assessed. Validate output schemas, calibration, and latency in your own workload before production use.
