GPT Image 2.5 and GPT Image 2: model names, reference editing and prompts
Check the official SDK identifiers, separate product labels from API names, and organize repeatable image edits.
What was verified
On September 20, 2026, OpenAI's Python SDK lists gpt-image-2 and its 2026-04-21 snapshot, plus gpt-image-2.5-flare, gpt-image-2.5-sunburst and their 2026-09-08 snapshots. A date embedded in an identifier does not establish availability across every product or account.
HUUUIAI displays G-Image 2.5, G-Image 2.5 Preview, G-Image2 and G-Image2 Preview. These are product entry names. Do not assume a Preview entry maps to a specific official variant, or infer free quotas, speed or pricing from an SDK model list.
Make each editing request a clear difference
If the subject drifts, return to the original reference. Packaging text, logos and facial structure need individual inspection rather than a general similarity check.
- Start with a clear reference and identify what must stay unchanged.
- Select a composition before refining details.
- Change one major property at a time.
- Compare untouched areas as carefully as the requested edit.
Product editing prompt
Preserve the product's shape, material, logo and position from the reference image. Replace only the background with a light gray photography surface. Use soft light from the left and a natural contact shadow. Add no text.
Compare on your own delivery tasks
Use the same references and output requirements across versions. Record usable outputs, editing rounds and total time. The prompt above is an editorial example, not a paid inference benchmark. API access and billing must be checked separately from HUUUIAI plans and credits.

Checked on the dates below. Prompts are editorial examples, not measured performance results. Model availability and parameters in HUUUIAI depend on the current service.
