GPT Image 2 vs Grok Imagine: technical and visual comparison

This compares two models that are available in the current Mixer AI catalog. The table below is built from current product controls, while the visual section shows what to inspect with the same inputs and prompt instead of inventing one universal winner.

Key differences

GPT Image 2: Create an image from a brief or edit an existing one with plain-language instructions.

Grok Imagine: Create images from a description and choose the version around whether you need to edit an uploaded photo.

Start with the specification table: it reflects current modes, input media, duration, resolution, aspect ratios and a normalized price where a fair comparison is possible.

Specifications

Spec	GPT Image 2	Grok Imagine
Model variants	GPT Image 2	Grok Imagine 1.0 / Grok Imagine 2.0
Generation modes	from text / photo editing	from text / photo editing
Input photos	up to 16	up to 1
Transparent background	Yes	No
Resolutions	1K / 2K / 4K	speed / pro
Aspect ratios	9:16 / 16:9 / 1:1 / auto / 4:3 / 3:4	9:16 / 16:9 / 1:1 / 2:3 / 3:2
Prompt limit	20,000 characters	5,000 characters
Price per image (different settings)	7 coins · 1K	5 coins · Auto

There is no shared resolution for a direct price comparison, so each price includes its setting and is not highlighted as cheaper.

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 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

Lock one prompt, aspect ratio and a duration or resolution that both models actually support.
If input modes differ, compare the shared workflow first and test each model's extra controls separately.
Run more than one attempt: a single output reflects one seed, not the model's overall consistency.
Score prompt adherence, visual artifacts, reference preservation and the cost of the setting you would really use separately.

FAQ

How should I compare GPT Image 2 and Grok Imagine fairly?

Use a workflow both models share, keep inputs and prompt identical, then run several generations. Compare prompt adherence, visual consistency and the price of the setting you need as separate dimensions.

Are both models available in Mixer AI?

Yes. This page is generated only for models in the current public Mixer AI catalog; if a model leaves the catalog, the automated comparison must stop passing validation.

Which model is better?

There is no universal answer. First eliminate a model that cannot accept the input, duration, resolution or format you need, then compare outputs on your own scene. The table highlights only measurable advantages in individual specifications.
