vLLM Releases Decision 3.0: Open Semantic Router Decision Models

Decision 3.0 represents a critical toolchain addition for building local AI agents without cloud dependencies. These open, multimodal models span a 0.6B to 27B parameter range, enabling practitioners to select appropriate model sizes for their hardware constraints while maintaining semantic routing capabilities. This addresses a key gap in self-hosted agent architectures where routing decisions have previously required either large general-purpose models or proprietary cloud APIs.

The multimodal aspect is particularly valuable for local deployments, as agents increasingly need to process both text and vision inputs for decision-making tasks. By releasing multiple model sizes, vLLM enables edge deployments to maintain full inference locally—crucial for privacy-sensitive applications and environments with limited or unreliable connectivity.

For practitioners building local agent systems, Decision 3.0 models offer a production-ready solution for the routing layer, complementing larger foundation models in an agentic stack. The open-source nature ensures compatibility with local serving frameworks like vLLM itself, making integration straightforward for on-device deployments.
