When to Use Gemini 2.5 Pro
Quality upgrade from Flash
When 1536px isn't quite enough but you don't need full 4K. Perfect for:
- Hero images on standard displays
- Featured blog graphics
- Product showcases
- Portfolio pieces
Image editing tasks
Gemini 2.5 Pro handles editing better than Flash:
- Modifying existing images
- Adding/removing elements
- Style adjustments
- Background changes
Production workflow
When you've iterated with Flash and need a higher-quality final output, but Nano Banana Pro is overkill.
When NOT to Use It
- Need maximum resolution → Use Gemini 3 Pro Image (4K)
- Need perfect text rendering → Use Gemini 3 Pro Image (Nano Banana Pro)
- Just experimenting → Use Gemini 2.5 Flash (faster, cheaper)
- Need photorealism → Use Imagen 3

Resolution Comparison
| Model | Resolution | Good For |
|---|---|---|
| Gemini 2.5 Flash | 1536x1536 | Thumbnails, social, iteration |
| Gemini 2.5 Pro | 2048x2048 | Hero images, features, quality work |
| Gemini 3 Pro Image | 4096x4096 | Print, 4K displays, maximum quality |
2048x2048 is the practical sweet spot for most web work - sharp on standard displays, reasonable file sizes, good enough for most hero sections.
