Semantic Router
A semantic router routes queries to the right workflow, toolset, or model using semantic signals (embeddings, intent classification, similarity to known categories).
Routing is how you keep outputs high-quality and cost-efficient across diverse audiences without bloating prompts for everyone.
Explanation
Instead of one monolithic "assistant," routing picks specialized paths: definition mode, troubleshooting mode, governance mode, tool-enabled mode, etc.
