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 2.6 Economy
The budget GPT Image 2.6: 1K PNG, a transparent background and editing with up to 16 photos.
- From text or from photos: 1 to 16 JPEG, PNG or WebP images, up to 30 MB each.
- 8 aspect ratios: Auto, 1:1, 16:9, 9:16, 3:2, 2:3, 21:9 and 4:3.
- 1K and PNG only: GIF and higher quality are not available.
- Check object edges and small lettering on a transparent background when zoomed in.
What to inspect with Grok Imagine
Create images from a description and choose the version around whether you need to edit an uploaded photo.
- 1.0: text with Speed or Pro priority, or editing one photo.
- 2.0: new images from text; Segment Edit starts from an eligible generated result. Five aspect ratios are available for generation.
- Segment Edit is not ordinary uploading of an arbitrary photograph into version 2.0.
- Inspect lettering, logos and small objects separately.
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.
