How AI describes Semantic Router (Aurelio Labs)

Aurelio Labs' Semantic Router is an open-source Python library that provides a deterministic decision-making layer for AI, routing requests to tools and actions via semantic vector space instead of relying on slow LLM generations. It serves as a superfast router for LLMs and agents, supporting static, dynamic, and guardrails-enabled routes to prevent hallucinated tool calls and scale to thousands of tools. It supports multiple encoders and model providers (OpenAI, Cohere, HuggingFace, Pinecone, etc.), can run locally or via APIs, and is released under the MIT license.
