GPT Image 2 model details
A detailed guide to GPT Image 2 for high-fidelity image generation, cleaner image editing, text-rich visuals, and resolution choices.
GPT Image 2 is the stronger choice when a project needs photorealism, sharper text rendering, pixel-level editing, and a finished-image workflow. Use it for campaign concepts, landing-page visuals, product treatments, localized graphics, and detailed image edits.
What is GPT Image 2 built for?
GPT Image 2 is an advanced AI image generator for detailed creative briefs, higher-resolution outputs, text-heavy layouts, and image editing workflows. It is useful when composition, typography, lighting, and final placement all need to be specified clearly.
- Campaign visuals
- Product treatments
- Text-rich layouts
- High-fidelity image edits
How should I choose 1K, 2K, or 4K?
Use 1K for quick iteration and smaller placements, 2K for sharper review candidates, and 4K for final hero images or high-detail inspection. Some aspect-ratio and resolution combinations are restricted, so GemiOmni blocks unsupported choices before generation.
- 1K for drafts
- 2K for polished candidates
- 4K for hero visuals
- Unsupported combinations are prevented
Does GPT Image 2 support image-to-image editing?
Yes. Upload source images when you want to preserve a person, product, composition, or style direction. Explain what should change and what should remain fixed so the model can recolor, replace, clean up, or localize without rebuilding the whole image.
- Up to 16 input images
- Preserve subject identity
- Specify changed regions
- Supports 30MB images
GPT Image 2 vs Nano Banana Pro: how do I choose?
Choose GPT Image 2 for OpenAI-style instruction following, resolution tiers, and long detailed prompts. Choose Nano Banana Pro when you want a premium image model focused on strong reference guidance and polished commercial-looking output.
- GPT Image 2 for long briefs
- Nano Banana Pro for reference polish
- GPT Image 2 for 4K tiers
- Nano Banana Pro for product concepts
What prompt structure works best?
Use a production brief: subject, setting, exact visual changes, lens or camera angle, lighting, mood, color palette, on-image text, negative constraints, and target placement. This helps GPT Image 2 turn a structured prompt into a coherent image.
- Production-brief prompts
- Precise visual changes
- Typography and localization
- Target placement
