What to compare visually
For a fair A/B test, use the same prompt, aspect ratio and references. Inspect more than overall style: object preservation, geometry, faces and hands, fine detail, text in the frame and unintended changes during editing.
What to inspect with GPT Image 2
Create an image from a brief or edit an existing one with plain-language instructions.
- Text or uploaded photos; choose 1, 2 or 4 results.
- 1K, 2K and 4K. Auto and transparent background require 1K; a 1:1 square is unavailable at 4K.
- Editing does not guarantee pixel-identical preservation of untouched areas.
- Compare faces, branding and fine lettering against the source at full size.
What to inspect with MiniMax H3 Image
Creates an image from text or edits up to 16 source images in 1K, 2K or 4K quality.
- Text-only input creates a new image; adding 1–16 source images selects image editing automatically.
- Choose 1K, 2K or 4K, ten aspect ratios, PNG output and 1, 2 or 4 results.
- Every reference image carries an additional charge, including the first; check the full quote before submitting.
- Review fine lettering, packaging, faces and tiny details against the source images.
How to run a fair comparison
- Give both models one prompt, one aspect ratio and, for editing tests, the same source photo.
- Look at the small things: hands, small text, product edges and logos fail differently in every model.
- Generate at least three variants per model: one picture shows one seed, not the usual quality.
- Compare cost at the resolution you will actually publish, not at each model's cheapest setting.
