What Makes GPT Image 2.5 Different?

Precise Image Editing Change what you need without rebuilding everything.

GPT Image 2.5 is designed for precise image editing. You can remove an object, change a specific part of an image, replace the background, or modify one visual condition while keeping the rest of the scene consistent.

Best for: Local edits · Background changes · Existing images

Better Control Over Details

You can describe more than just the subject. Add instructions about composition, lighting, colors, positioning, typography, or other details that matter to the final image.

The result can be much closer to the original idea when the prompt contains clear visual instructions.

Best for: Detailed scenes · Layouts · Visual concepts

High-Quality Text & Layouts Create visuals that contain real information, not just decoration.

AI-generated text has historically been one of the harder parts of image generation. GPT Image models are designed to handle text inside images, making them useful for posters, advertisements, product graphics, diagrams, social media visuals, and other designs where readable text matters.

Best for: Posters · Graphics · Advertisements

Flexible Quality & Output Choose the right balance between speed, quality, and resolution.

Both Flare and Sunburst models support auto, low, medium, high, xhigh, and max quality settings, giving you more control over the generation workflow.

The models also support flexible resolutions, including square, landscape, portrait, 2K formats, and larger resolutions up to 3840×2160 under the documented limits.

GPT Image 2.5: Sunburst or Flare?

This is actually worth having as a small comparison table because it answers a question users may have immediately.

Feature	Sunburst	Flare
Main focus	Editing precision	Speed
Best for	Complex editing	Everyday generation
Image generation	√	√
Image editing	√	√
Transparent background	√	√
High-quality modes	√	√
Best choice	When accuracy matters	When speed matters

OpenAI's own guidance is essentially: start with Flare when speed is the priority, and use Sunburst when demanding quality or editing precision is the priority.
