Report #77214

[frontier] How do I route user queries to the correct specialized agent in a multi-agent system with sub-10ms latency suitable for edge deployment?

Pre-compute embeddings for all agent capability descriptions using a fast local model \(voyage-3-lite, bge-small\), store in SQLite or Redis with cosine similarity index, and route by embedding similarity rather than calling an LLM for routing decisions.

Journey Context:
Using an LLM \(even GPT-4o-mini\) to decide 'which agent should handle this' adds 100-500ms latency and costs tokens per request. The fix treats routing as a classification problem solvable with vector similarity: embed the user's intent and match against pre-defined agent descriptions. The frontier insight for 2025 is using tiny local embeddings \(voyage-3-lite, bge-small\) in SQLite for zero-network-latency routing in edge deployments. This achieves <10ms routing vs 300ms\+ for LLM routing. Alternatives like hardcoded keyword matching is brittle; LLM routing is too slow for real-time apps.
