GPT Image 2.5 Review: What Actually Improved
We tested GPT Image 2.5 against GPT Image 2, Nano Banana 2 Premium, and Midjourney V7 to see what actually improved in generation speed, prompt following, text rendering, editing, and visual consistency.
Key takeaways
- GPT Image 2.5 showed its clearest gains in speed, prompt following, text rendering, editing consistency, and control rather than raw image quality.
- In our Kyoto poster test, GPT Image 2.5 finished in 40 seconds versus 63 seconds for GPT Image 2.
- In our Kyoto poster test, GPT Image 2.5 finished in 40 seconds versus 63 seconds for GPT Image 2.
- Midjourney V7 produced the stronger aesthetic result in our fashion test, while GPT Image 2.5 followed the requested details more closely.
- GPT Image 2.5 preserved source images more consistently during targeted edits across both editing tests.
