Body Builder (beta)
Body Builder (beta) from OpenRouter has no benchmark data, an unusual pricing structure, and no clear capability profile — it cannot be recommended for any business application at this stage. It appears to be an experimental or beta offering with no substantiated performance claims.

Transform your natural language requests into structured OpenRouter API request objects. Describe what you want to accomplish with AI models, and Body Builder will construct the appropriate API calls. Example: "count to 10 using gemini and opus." This is useful for creating multi-model requests, custom model routers, or programmatic generation of API calls from human descriptions. **BETA NOTICE**: Body Builder is in beta, and currently free. Pricing and functionality may change in the future.
