Models

List image models

OpenRouter's image model list: one entry per image model your key may call, with architecture (text in, image out), supported_parameters, supports_streaming (always false) and endpoints, the relative URL of its endpoints listing. supported_parameters names each field the model takes with its values: resolution, aspect_ratio, quality, output_format, background and size as enums of the declared values, n and output_compression as ranges, seed as a boolean. OpenRouter lists size as a boolean; here its enum says which sizes the model accepts. A key is required, and the answer is never cached.
