Sample code and API for GPT-5.4 Image 2

OpenRouter normalizes requests and responses across providers for you.

OpenRouter supports image generation models that can output both text and images. 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.
