Midjourney vs Seedream 4.5: 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.

Seedream 4.5: Product scenes, characters and reference-based edits at 2K or 4K.

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	Midjourney	Seedream 4.5
Model variants	V8.2 / V8.1 / V7	Seedream 4.5
Generation modes	from text	from text / photo editing
Input photos	No	up to 14
Resolutions	fast / fast_hd	2K / 4K
Aspect ratios	9:16 / 16:9 / 1:1 / 4:3 / 3:4 / 3:2 / 2:3 / 2:1 / 1:2	9:16 / 16:9 / 1:1 / 4:3 / 3:4 / 3:2 / 2:3 / 21:9
Prompt limit	4,000 characters	3,000 characters
Price per image (different settings)	8 coins · draft	7 coins · 2K

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 Midjourney

Explore a visual direction through lighting, material, composition and mood.

8.2 and 8.1: text-based generation in Fast and Fast HD.
7: Fast, Turbo, Draft and Omni with one image. Available modes depend on the version.
This is not a replacement for precise local photo retouching.
Omni belongs to version 7 in this integration; it does not automatically carry into 8.1 or 8.2.

What to inspect with Seedream 4.5

Product scenes, characters and reference-based edits at 2K or 4K.

Text or up to 14 input photographs.
2K or 4K, 8 aspect ratios and 1, 2 or 4 results.
References supply material for a composition, not a guarantee of unchanged pixels.
Fine lettering, fingers and intersecting objects may need another edit.

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 Midjourney and Seedream 4.5 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.
