Select the optimal LLM to handle your query based on Not Diamond's routing algorithm.

This endpoint analyzes your messages and returns the best-suited model from your specified models. The router considers factors like query complexity, model capabilities, cost, and latency based on your preferences.

Key Features:

• Intelligent routing across multiple LLM providers
• Support for custom routers trained on your evaluation data
• Optional cost/latency optimization
• Function calling support for compatible models

Usage:

1. Pass your messages in OpenAI format (array of objects with 'role' and 'content')
2. Specify which LLM providers you want to route between
3. Optionally provide a preference_id to use a custom router that you've trained
4. Receive a recommended model and session_id
5. Use the session_id to submit feedback and improve routing
