GPT Image 1
GPT Image 1 is an image generation model from OpenAI that supports configurable sizes, backgrounds, and source image inputs.
OpenAIText-to-image generation with background control
GPT Image 1 is an image generation model developed and published by OpenAI, released in April 2025. It accepts text prompts alongside optional source images and configuration inputs for output size and background style, making it suitable for both generative and image-editing workflows. The model operates with a 4,000-token context window for prompt input and is available as a first-party model on MindStudio.
GPT Image 1 is designed for use cases that require controllable image output, including generating images with transparent or custom backgrounds and compositing from existing source images. Its input structure — which includes an image URL array — allows users to supply reference images as part of the generation process. This makes it applicable to product photography, design mockups, and other tasks where visual consistency with existing assets matters.
What GPT Image 1 supports
Image Generation
Generates images from text prompts with a 4,000-token context window for detailed instructions.
Background Control
Supports configurable background settings, including transparent backgrounds, giving control over how generated images are composited.
Source Image Input
Accepts an array of source image URLs as reference inputs, enabling image editing and style-consistent generation from existing visuals.
Output Size Selection
Allows users to select from available output size options to match the target format or aspect ratio of the generated image.

What is the context window for GPT Image 1?
GPT Image 1 has a context window of 4,000 tokens, which applies to the text prompt input used to guide image generation.
What input types does GPT Image 1 support?
The model accepts three input types: a size selector, a background selector, and an array of source image URLs. This allows both pure text-to-image generation and image-to-image workflows.
Can GPT Image 1 generate images with transparent backgrounds?
Yes. The background input field supports configurable background options, which includes the ability to generate images with transparent backgrounds.
Who publishes GPT Image 1?
GPT Image 1 is published by OpenAI and is available as a first-party model, meaning it is provided directly by the model's creator.
When was GPT Image 1 released?
GPT Image 1 was released in April 2025 and was added to MindStudio on April 24, 2025.
What people think about GPT Image 1
Community discussion around GPT Image 1 and its successor GPT Image 1.5 has been largely positive, with users highlighting strong instruction following, realistic character rendering, and high placement on image generation leaderboards. The most upvoted threads focus on creative use cases such as converting video game characters into photorealistic portraits and comparing output quality across model versions.
Some threads draw direct comparisons between GPT Image 1, GPT Image 1.5, and a smaller variant called GPT Image 1 Mini, suggesting users are actively evaluating which version suits their needs. Concerns and limitations discussed tend to center on differences in output fidelity between quality tiers rather than fundamental capability gaps.
