Best RouteLLM Alternatives in 2025
-
Semantic routing is the process of dynamically selecting the most suitable language model for a given input query based on the semantic content, complexity, and intent of the request. Rather than using a single model for all tasks, semantic routers analyze the input and direct it to specialized models optimized for specific domains or complexity levels.
