Decision 3.0 is a new set of open multimodal models from the vLLM Semantic Router project. Unlike general-purpose language models that generate free-form text, these models are purpose-built for decision tasks: they accept text and image inputs and return a choice, a yes/no answer, or a numeric score directly, without producing a text response.
The family spans five model sizes from 0.8B to 27B parameters, all released under the permissive Apache-2.0 license. This range lets practitioners pick a model that fits their accuracy requirements and compute budget, from edge-friendly small models to larger ones for higher-stakes classification.
The key design choice is skipping text generation entirely. In production pipelines that need to route, filter, or score content, generating a full sentence just to extract a label adds latency and cost. By outputting structured decisions directly, Decision 3.0 models can be faster and cheaper to run at scale.
Integration with vLLM, a widely adopted inference engine, suggests the models are optimized for high-throughput serving. For teams building AI agents, content moderation systems, or multimodal routing layers, this release offers a ready-made open alternative to proprietary classifiers or fine-tuned general LLMs.
