About Body Builder (beta)
Designed as a beta release on the Openrouter platform, Body Builder processes extended text inputs up to 128000 tokens while remaining fully proprietary. Its architecture focuses on coherent, multi-turn conversations without public weights. This setup allows consistent handling of complex queries over long sessions.
Strengths include maintaining context across detailed discussions and producing structured textual outputs suited to planning scenarios. The model avoids open-weight distribution to control access and updates through Openrouter only. Typical usage involves generating workout descriptions, nutrition outlines, and progress tracking narratives.
Users commonly interact with it for iterative refinement of fitness strategies where large context helps track evolving details. It supports text modality exclusively, making it ideal for written reports rather than multimodal tasks.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "openrouter/bodybuilder",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: openrouter/bodybuilder
