GPT Image 2.5 brings OpenAI's Flare and Sunburst image generation and editing workflows into one focused Kuca workspace. Start from a written brief or upload as many as 16 source images, choose a supported square, portrait, landscape, panoramic, or extra-wide ratio, then render at 1K, 2K, or 4K. Use Flare for the balanced default workflow or Sunburst when premium creative work benefits from tighter control across edits.
OpenAI's launch gallery demonstrates the range it associates with Images 2.5: coherent world building, graphic layouts with readable type, painterly style control, ornate print design, and character-led merchandise art.
Kuca exposes both official API models for text generation and reference-led editing. Keep the creative goal constant when comparing them, then judge fidelity, local edit precision, layout, and revision effort.
Faster for everyday image production
OpenAI positions Flare as the default option for most applications. It combines the new model family's gains in image quality, editing, and latency for creator content, product experiences, visual search, rapid prototyping, and higher-volume generation.
More precise for premium creative work
OpenAI positions Sunburst for premium visual workflows that benefit from tighter control across edits. It suits polished product imagery, production-ready campaign creative, and branded assets where each revision must preserve the approved direction.
The 2.5 generation is not a renamed GPT Image 2 workflow. It adds two production paths, so model choice becomes part of the brief before resolution or references are configured.
Choose Flare when turnaround and volume matter. It is positioned as the faster, balanced path for creator content, product experiences, visual search, and rapid iteration.
Choose Sunburst for premium assets where local edits, brand direction, and continuity between revisions deserve more weight than the fastest first result.
Keep the prompt, reference set, aspect ratio, and review criteria constant. A matched comparison reveals differences in fidelity and revision effort instead of differences caused by the setup.
Treat an older prompt as a starting point, not a guaranteed preset. Recheck typography, protected reference details, crop, and credit cost in 2.5 before adopting it for repeat production.
Use one brief, one reference set, and matching output settings when you compare the two GPT Image 2.5 variants. A controlled setup makes differences in speed, fidelity, and revision effort easier to judge.
Editing accepts up to 16 reference images. Use the same purposeful set for Flare and Sunburst, and give each source a clear role such as identity, product shape, composition, or style. This keeps the comparison focused on the models rather than different inputs.
Each uploaded image can be no larger than 30 MB. Check the actual file size before starting a long brief, especially when working with camera originals or exported design files. If a file is too large, create a clean web-ready copy that preserves the important subject, edges, texture, and readable details without unnecessary metadata.
Choose the same supported aspect ratio and resolution for both variants. Start with a lighter output for direction tests, then increase the resolution only after selecting the stronger composition. More pixels do not correct an unclear brief or conflicting references.
State which identity, object, product detail, layout, or typography must survive each edit. Resolve incompatible lighting, camera angles, or brand details in the prompt, use only material you are allowed to upload, and review both variants before publishing.
Flare is the faster, balanced default for everyday creation and higher-volume iteration. Sunburst is aimed at premium work where precise edits, protected details, and continuity across revisions deserve more weight.
Yes. The editing workflow accepts up to 16 input images. Keeping the prompt, reference set, aspect ratio, and resolution unchanged is the clearest way to compare how Flare and Sunburst preserve identity, layout, and style.
Run the same brief through both and evaluate instruction adherence, reference fidelity, text and layout, local edit precision, and the number of revisions needed. Do not change several settings between outputs.
Start with Flare for general image creation, quick exploration, and repeat production. Try Sunburst when the asset is high-value or the edit must preserve an approved product, character, layout, or brand direction more carefully.
Move a workflow when a matched test shows better fidelity or fewer revisions for your actual brief. Recheck typography, protected reference details, crop, and credit use instead of assuming an older prompt behaves identically.
The live generator displays the credits required for the selected variant, mode, and settings before submission. Check that value again whenever you switch between Flare and Sunburst or change the configuration.
Open the Kuca image workspace, keep the setup consistent, and choose the GPT Image 2.5 variant that needs fewer compromises for your final asset.
