What is WhichModel and how does it work with AI agents?

WhichModel is an open MCP server that recommends LLMs based on task, complexity, budget, and capabilities. Add to your agent's config; query recommend_model() for picks.

Can WhichModel really save 90% on AI costs?

Yes, for many tasks—route simple jobs to cheap models like Gemini Flash ($0.60/M-token) vs. GPT-4o ($15/M). Projections show $6k+/month at 10k calls/day.

Is WhichModel free and open source?

Totally—MIT license, no API key. Remote at whichmodel.dev/mcp or self-host with npx.
