What is Decision 3.0? vLLM Semantic Router’s New Open Decision Models

Quick take

vLLM Semantic Router launched Decision 3.0, offering five open multimodal decision models ranging from 0.8 billion to 27 billion parameters. These models answer choice, yes/no, and scoring questions about text and images in a single API call. Importantly, they do this without generating additional text, which streamlines decision-making tasks that combine visual and textual inputs.

Why it matters

Decision 3.0 shifts AI beyond generating language toward direct decision outputs. For builders and businesses dealing with complex inputs, this means faster and more efficient workflows without the overhead of parsing generated text. It lowers latency and computational costs by focusing on decision-type responses, making it suitable for use cases like content moderation, form validation, or quick multi-modal QA. The multimodal aspect lets operators combine text and images within one call, reducing system complexity and integration effort.
