# GPT Image 2.5

> Canonical: https://stable-diffusion-web.com/gpt-image-2-5

Start with a familiar brief and inspect where the output differs from your existing image results. Keep the same subject and composition while trying Sunburst and Flare separately; neither variant is a Stable Diffusion checkpoint.

## GPT Image 2.5 model comparison

### Is this a Stable Diffusion checkpoint?

GPT Image 2.5 is offered through Kie as two distinct variants. It is not a checkpoint that accepts your Stable Diffusion sampler or LoRA settings.

## Technical specs

### 20,000

Prompt characters

### 30 MB

Per reference file

### 1K–4K

Output size options

### 1–4

Images per batch

## Who should use model comparisons?

### A practical starting point

Image makers evaluating a different generation family can compare the same visual brief against their current checkpoint workflow.

## Questions about model comparison

### What are the reference requirements?

Supply JPEG, WebP or PNG files no larger than 30 MB apiece. The workspace limits a request to ten references and trims prompts beyond 20,000 characters.

### Does every crop support 4K?

The four additional crops—8:9, 9:8, 16:27 and 27:16—stop at 1K. Square, auto and the remaining supported ratios can use 2K or 4K.

### How does background removal work?

Select Transparent. For high-resolution Sunburst edits, request extraction of the subject with no backdrop or cast shadow. Examine edges in the output rather than assuming a perfect cutout.

### How many credits does GPT Image 2.5 use?

GPT Image 2.5 draws between 10 and 30 credits per run, depending on the model and length chosen in the form.

### What limits should I check before using GPT Image 2.5?

Generated output from GPT Image 2.5 can contain visual, audio, or factual errors. Review each result before publishing, and upload only material you are authorized to use. Where the form accepts a reference image, supported files are JPEG, PNG, WebP up to 30 MB each.

### What happens to the files I upload to GPT Image 2.5?

An upload is stored against your own account, not pooled with other people's. Deleting the account removes it: the control is in Settings under Security, the request is confirmed by email, and the erasure removes the stored objects it owns. How long anything else is kept, and which processors handle it, is stated in the privacy policy.

### Can I use what GPT Image 2.5 makes commercially?

Every paid plan includes a commercial licence for what GPT Image 2.5 makes; the free tier is for personal use.

### How does GPT Image 2.5 compare, and what alternatives fit a different workflow?
