GPT Image 2 on MuoGen
GPT Image 2 supports image references, 1K/2K/4K settings, low/medium/high quality choices and selectable output formats in the MuoGen catalog.
Prepare an image with selectable formats and references
Compare GPT Image 2 when you need explicit quality, file format and background settings. Its quality choices are low, medium and high; compare these actual controls rather than assuming all image models expose the same settings.

These capabilities describe the settings exposed by MuoGen, not a guarantee of visual quality. Check the model and its settings in the workspace before preparing a request. Catalog checked on .
How do I prepare the prompt and references?
For a visual variation, identify the reference’s role before describing the changes. Specify composition, lighting and elements to preserve. Select the resolution and ratio together because the available combinations differ.
Example brief to adapt
Use the reference for the chair’s shape. Place one chair in a bright room beside a window, with a neutral wall and a full view of the legs. Keep the design recognizable.
This example is a preparation brief, not a generated result or a promise of output. Use only references you have the right to upload.
What limitations should I plan for?
Several references can express conflicting instructions. Describe the role of each one and remain within both the per-image size limit and the total upload limit. A high reference count is not a guarantee of exact identity preservation.
Can I generate with this model today?
The catalog and settings are available to explore. Paid generation in the public browser workspaces is not yet open. When enabled, it will require a verified account and paid credits. Preparing a prompt or reading this guide does not start a generation.
