AI image generation and editing
What is GPT Image 2.5?
GPT Image 2.5 is an AI image generator and editing model for turning detailed prompts into new visuals or refining existing images with reference guidance. Use the workspace for product concepts, campaign graphics, posters, character variations, and focused image edits without switching tools.
Generation modes and editing controls
Text-to-image generation
Describe the subject, composition, lighting, materials, typography, and constraints. GPT Image 2.5 turns that creative brief into a new image at the selected aspect ratio and resolution.
Reference-guided image editing
Upload up to 16 images and state what each reference should control. Ask GPT Image 2.5 to preserve the important subject, layout, or product details while changing selected parts.
Complex prompt control
Use a prompt of up to 20,000 characters for layered creative direction. Keep instructions structured, name what must stay unchanged, and proofread all generated text before publishing.
Where this image workflow fits
Start from the job the image needs to do. A clear destination makes it easier to choose references, set the composition, and judge whether a result is ready to keep.
Campaign concepts and social assets
Explore art direction for launch graphics, event posters, thumbnails, and social posts before committing to a final layout. State the channel, audience, message hierarchy, and required copy so each draft can be evaluated against the same brief. Generate a small set of deliberate variations, then compare legibility, focal point, and room for brand elements instead of changing every visual variable at once.
Product scenes and catalog variations
Place a product reference into new backgrounds while describing which details must remain consistent, such as silhouette, material, label position, and camera angle. Use separate prompts for clean catalog framing, lifestyle context, and seasonal concepts. Review edges, reflections, small typography, and proportions at full size before treating any generated image as production-ready.
Character, layout, and style exploration
Develop visual directions by assigning each reference a single purpose: identity, pose, palette, composition, or texture. Keep the important constraints stable while testing one change per round. This makes results easier to compare and gives the next prompt a concrete correction, whether the issue is expression, spacing, lighting, background detail, or overall visual balance.
A practical image creation workflow
Start with one clear outcome, then refine one visible variable at a time so each generation teaches you what to change next.
- 1Choose text-to-image for a new visual, or upload references when the task is an edit, variation, or visual combination.
- 2Write the subject and intended use first, then add composition, lighting, style, text, and preservation constraints.
- 3Select an aspect ratio and 1K, 2K, or 4K output. Use 1K for 27:16, 16:27, 9:8, and 8:9.
- 4Inspect faces, hands, logos, small geometry, and typography at full size, then revise only the instruction that missed the brief.
Prompt patterns for controlled image creation
A useful GPT Image 2.5 prompt reads like a compact art direction brief: define the result, assign each reference a role, describe the visual hierarchy, and finish with explicit constraints.
Product image prompt
Create a premium studio product image of the supplied ceramic bottle on warm limestone. Preserve the exact silhouette, cap, label layout, and logo. Use soft side light, a subtle floor reflection, and open space on the left for campaign copy. Do not add props or extra text.
AI poster prompt
Design a vertical editorial poster for a night design festival. Place “CITY AFTER DARK” as the main headline and “12–14 SEPTEMBER” below it. Use cobalt blue, silver, and black, strong grid alignment, one abstract light sculpture, and generous margins. Preserve every supplied character exactly.
Precise image editing prompt
Use reference one for the person and outfit, and reference two only for the room palette. Replace the daytime window view with a rainy evening city, keep the face, pose, clothing details, furniture, crop, and camera angle unchanged, and add no new objects.
GPT Image 2.5 credit pricing
The workspace shows the charge before submission: 10 credits for 1K, 20 for 2K, or 30 for 4K output. A paid plan or credit pack is required for 2K and 4K. If generation cannot be completed, credits are returned automatically.
Questions about generation and editing
Can GPT Image 2.5 generate and edit images?
Yes. Start without a reference for text-to-image generation, or upload one or more images for reference-guided editing. The workspace selects the appropriate generation mode automatically.
How many reference images can I upload?
You can upload up to 16 reference images. Use only the references that affect the result, and explain the role of each one in the prompt.
Which GPT Image 2.5 resolutions are available?
Choose 1K, 2K, or 4K. The 27:16, 16:27, 9:8, and 8:9 aspect ratios are limited to 1K in this workspace; other listed ratios support all three resolutions.
How should I write a precise image editing prompt?
Name the element to change, describe the desired replacement, and list what must remain unchanged. For multiple references, assign each image a specific role instead of asking the model to infer it.
