How to Add Cost-Aware Model Selection to Your AI Agent

The tutorial shows how to add dynamic, cost-aware model selection to an AI agent using WhichModel.

WhichModel is an open MCP server that tracks pricing and capabilities for more than 100 LLM models.

It helps avoid maintaining your own pricing database, update process, and routing logic.

Routing patterns include task-based recommendations, per-call budget caps, and cost comparisons.

MCP clients can connect through a remote URL, or stdio clients can use npx with whichmodel-mcp.
