GPT Image 3 vs GPT Image 2.5: What to Test and What Is Known
A controlled GPT Image 3 versus GPT Image 2.5 comparison framework for realism, text, editing, speed, price and reliability. No fake pre-release scores.
Quality benchmark
Compare identical prompts across photorealism, text, dense composition, product consistency and controlled editing.
Production benchmark
A better-looking image is not enough for a production switch. Measure operational behavior under the same workload.
Current provisional answer
There is no evidence-backed winner because GPT Image 3 has not been officially identified. Claims of guaranteed 4K, perfect text or superior consistency are premature.
Frequently asked questions
Is GPT Image 3 better than GPT Image 2.5?
