GPT Image 2.5 FAQ

What can I do with GPT Image 2.5?

Use GPT Image 2.5 Flare / Sunburst on Flux Art to create images from text or edit a reference image. Try product photos, posters and everyday creative ideas.

How do I edit an existing image?

Select image editing and upload a reference. Describe what to change and which subject, colors and viewpoint to preserve, then choose quality and dimensions. Compare the result with the original.

Which quality levels are available?

Choose low, medium, high, xhigh, max or auto. Fixed quality selections are submitted without downgrading. Auto reserves the maximum charge and refunds unused credits after generation.

Does GPT Image 2.5 support 4K and custom sizes?

Flux Art offers 1K, 2K, 4K and custom dimensions. Edges must be multiples of 16, the aspect ratio must be between 1:3 and 3:1, each edge must be at most 3840 pixels, and total pixels must be 655,360–8,294,400.

How are GPT Image 2.5 credits calculated?

Pricing depends on quality, dimensions and image count. Custom sizes are assigned by total pixels: up to 1024² is 1K, up to 2048² is 2K, and larger sizes are 4K. During the promotion, you pay 50% of standard credits. Check the generation button before submitting.

Should I choose Flare or Sunburst?

Start with Flare for quick everyday ideas, or try Sunburst when precise reference-image editing matters more. Compare results using the same brief to find the better fit for your task.

Are the examples actual generated images?

Follow along: from a brief to a product image

Start with a ceramic cup: describe the image, choose your settings, then use the result as a reference for a new scene.

  1. Choose a model and describe the scene

    Select image generation above. Start with Flare to explore a composition; both models support text-to-image. Describe the subject, placement, background, lighting and exclusions.

    A prompt to try

    Create a landscape product hero for an ivory ceramic coffee cup. Place the cup on the right against a warm light-grey background. Leave clean negative space on the left. Use soft side lighting and fine ceramic texture. Add no text or logos.

    For text in an image, specify the exact wording and placement, such as: put “Morning Coffee” in the top-left corner.

  2. Check composition before refining the output

    Start at 1K and medium quality to review the result, or use low to explore a direction. Once the composition works, try high, xhigh or max as needed. Fixed quality is submitted as selected; Auto lets the model choose.

    Choose 1K, 2K or 4K, then a ratio for the intended use: 1:1 for a square product image, 3:2 for a landscape cover, or 2:3 for a portrait poster. Quality and dimensions are separate controls.

    For exact dimensions, open custom size and enter width and height. Resolve any validation messages before submitting, and check the credits shown on the generation button.

    Review the cup’s placement, negative space and lighting. Adjust the prompt if these are wrong before increasing quality.

  3. Upload a reference and focus the edit

    Switch to image editing and upload the product image. Continue with Flare, or compare Sunburst when preserving details matters. Separate what must stay from what should change, and focus on one change per edit.

    A scene-change prompt

    Keep the reference product shape, colour, packaging text and camera angle. Change only the background to a wooden table with natural window light. Match the original light direction and add contact shadows. Do not add extra products.

    Compare the rim, handle, color and angle at full size. Download a result you like, and use that version for the next edit rather than continuing from an incorrect image.
