Report #61083
[frontier] Intent classifiers creating brittle routing logic in multi-agent systems
Replace LLM/intent-based routing with 'Semantic Vector Routing'—embedding the incoming task and performing k-NN against agent capability vectors in real-time.
Journey Context:
Teams build router agents that use few-shot prompting or fine-tuned classifiers to decide which sub-agent handles a task. This adds 500ms-2s latency and fails on novel queries. The shift is to treat routing as a retrieval problem: embed the user query, compare against a vector index of agent capability descriptions \(updated dynamically as agents register\), and route via pure vector similarity. This is sub-100ms, requires no LLM call for routing, and gracefully handles novel inputs via embedding space proximity.
