    Sample code and API for FLUX.2 Flex

    OpenRouter normalizes requests and responses across providers for you.

    OpenRouter supports image generation through models that have image in their output modalities. These models can create images from text prompts when you specify modalities: ["image", "text"] in your request. The generated images are returned as base64-encoded data URLs in the assistant message. Learn more about image generation.

    In the examples below, the OpenRouter-specific headers are optional. Setting them allows your app to appear on the OpenRouter leaderboards.
