Image Models

List available image generation and image editing models with capabilities and supported parameters

Overview

Use GET /api/v1/image-models to discover the currently available image models and their capabilities. Do not hardcode image model capability tables in your client; model availability and supported parameters can change.

This endpoint is cacheable. Refresh it periodically and handle new fields as additive.

Endpoint

GET https://nano-gpt.com/api/v1/image-models

Supported Parameters

Supported parameters vary by model. Common fields include:

• resolutions: array of supported resolution values for this model.
• max_images: maximum number of images that can be requested at once.
• rendering_speed: available rendering speed values, when the model exposes speed tiers.
• fixed_image_count: fixed output count for models that do not allow custom n.

Use supported_parameters.resolutions to populate resolution or size controls. Treat the values as model-specific strings. Most image generation models use pixel dimensions such as 1024x1024, but some models use values such as auto, aspect ratios, quality tiers, or scale factors.

Use the model’s supported_parameters and capabilities objects to decide which controls to show and which request fields to send.

Fields

Field	Type	Description
id	string	Model ID to pass to image generation or image editing endpoints.
object	string	Always model.
created	integer	Unix timestamp derived from the model’s added date.
owned_by	string	Provider or owner identifier.
name	string	Human-readable model name.
description	string	Short model description.
architecture	object	Modality metadata, including input and output modalities.
pricing	object	USD pricing metadata. Shape can vary by model.
capabilities	object	Feature flags such as image_generation, image_to_image, and inpainting.
capabilities.nsfw	boolean	Whether the model is uncensored / NSFW-capable.
supported_parameters	object	Model-specific parameters such as sizes, counts, quality settings, seeds, or image input controls.
supported_parameters.resolutions	string[]	Model-specific supported output resolution values. Usually pixel dimensions like 1024x1024; may also be symbolic values such as auto or model-specific scale factors.
supported_parameters.max_images	integer	Maximum number of images the model supports per request.
supported_parameters.rendering_speed	string[]	Optional list of rendering speed tiers. Present only for models that expose speed choices.
supported_parameters.fixed_image_count	integer	Optional fixed output image count. Present when the model always returns a fixed number of images.
icon_url	string	Optional provider icon path.
tags	string[]	Optional model tags.
category	string	Model category. Usually image.

supported_parameters, including supported_parameters.resolutions, is included only in detailed responses. detailed=true is the default. If you pass detailed=false, each item may include only basic identifiers such as id, object, created, and owned_by.

Example

curl "https://nano-gpt.com/api/v1/image-models?detailed=true" \
  -H "Authorization: Bearer $NANOGPT_API_KEY"

Notes

• Supported parameters vary by model.
• Use this endpoint instead of hardcoding media model capabilities.
• The response is cacheable, but model availability can change.
• Pricing values are in USD unless otherwise documented in the response.
