About

Body Builder (beta) is an OpenRouter model designed to turn natural-language requests into structured OpenRouter API request objects. A user describes the task they want to accomplish with AI models, and Body Builder constructs the corresponding API calls. It accepts text and produces text. Its context window is 128,000 tokens, and its model id is openrouter/bodybuilder. The listed release date is 2025-12-05. The entry identifies it as beta, so its stated role is specifically request construction rather than a general-purpose model task. No tool support, vision capability, other input type or output type is listed. The listed input and output prices are each -1000000 USD per 1M tokens; these values are presented exactly as supplied rather than interpreted. Its official site is https://openrouter.ai/openrouter/bodybuilder. Builders can assess it as a text-based way to translate an expressed goal into a structured OpenRouter API request.

Who it is for

Body Builder suits builders who want to describe an AI-model task in natural language and have it turned into an OpenRouter API request object. It is a fit for text-only request construction.

  • Accepts text and returns text.
  • Context window is 128,000 tokens.

What to know first

Verdict
