Seedream 5.0 Pro Edit vs Wan 2.7 Pro Edit
Identical price, and the clearest speed-against-quality trade in the image catalogue. Wan 2.7 Pro Edit returns in a fraction of the time at the median; Seedream 5.0 Pro scores materially higher on the blind index, and both have real production volume behind their numbers.
Both engines run in the WowMade image studio, so every number below comes from the same production queue rather than from either vendor. Blind quality index v0.1, run 2026-09-02; speed and completion measured over a rolling 60-day window.

The same numbers, seen
Five views of the table above: how long the wait actually feels, how wide the slow tail runs, where these two sit among every engine we measure, how much blind score each credit buys, and what a job of your size costs on each.
A finished image is the flag. Median means half of all runs land faster than this, half slower.
Engines without a blind score yet are not plotted. Hover a grey dot for its name.
Higher is more blind-index score per credit spent. Built from a v0.1 index, so it inherits that index’s uncertainty — bars within a few percent of each other are not ranked, and an engine with no score is absent rather than last.
At 9 runs, Seedream 5.0 Pro Edit costs $0.00 less than Wan 2.7 Pro Edit. A Start plan at $25 carries 75 credits, Go $60 carries 250, Premium $95 carries 500. Plans renew monthly until cancelled and can be cancelled online at any time.
The same prompt, on both
A blind score is a number, not a picture, and at this end of the index the numbers sit close enough that the picture is the more useful of the two. Here is one brief run on each engine, at its own settings.

AI generated with Wan 2.7 Pro Edit
Both were run from the one prompt every engine on the site is given, each at its own settings — the same sample each shows on its own model page. Nothing is retouched and nothing is cherry-picked. Paste it into the studio and you can run it yourself:
A colossal whale carved from liquid mercury breaches through a sea of floating obsidian shards, molten gold light pouring from the seams in its hide, slow orbital camera, volumetric god rays, drifting embers, hyper-detailed, cinematic, no people

What each one is
Seedream 5.0 Pro Edit
ByteDance flagship editor. Top detail and prompt precision, full control over aspect ratio and resolution.
ByteDance · 2,212 production edits measured · scored over 2 judged prompts
Wan 2.7 Pro Edit
Up to 2K output, multi-image reference up to nine, superior editing quality.
Alibaba · 807 production edits measured · scored over 2 judged prompts
This is the pair where the scores genuinely separate. Most comparisons in the image catalogue come down to a point or two, which is inside the noise; here the gap is wide enough to act on, and both sides have enough traffic that neither number is provisional.
The speed difference is just as real in the other direction. At the median, one of these comes back in a small fraction of the time the other takes, which changes an editing session from a series of waits into something closer to interactive.
Since the price is identical, the rational strategy is to use the quick one to explore and the higher-scoring one to finish. That is not a compromise — it is the pattern this pair is best suited to, and it costs no more than committing to either.
How to read the table
Median is the middle time across the window, so half of all runs land faster than the figure shown. p90 is the slow tail: nine runs in ten finish inside it. The gap between the two is the number to watch when you are planning a session — Seedream 5.0 Pro Edit spreads from 47 s to 83 s, Wan 2.7 Pro Edit from 13 s to 78 s. A wide spread means the queue, not the model, decides your afternoon.
Completion rate is the share of submitted runs that finished. It is not a quality measure — a run can complete and still be wrong for you — but a low rate means retries, and retries cost credits. Quality is a blind score out of 100 and is only comparable inside this index; it is not a vendor benchmark and it is not comparable to anyone else’s number.
What the numbers do not say
Wan 2.7 Pro Edit is fast at the median but its slow tail runs much further out than its typical edit, so an occasional run will take far longer than the headline figure suggests.
Where each one wins
Choose Seedream 5.0 Pro Edit when
- Output quality is the thing being judged and the score gap here is wide enough to act on.
- The edit has to hold a face or a product identity through a restyle.
- You want the highest reference-image ceiling in the catalogue.
Choose Wan 2.7 Pro Edit when
- You are exploring and want edits back fast enough to keep a train of thought.
- You are working through a queue of straightforward edits where turnaround dominates.
- You want a second take on the same prompt cheaply, given both cost the same.

How these numbers were produced
Quality is the WowMade Image Quality Index v0.1, run 2026-09-02: every engine runs the same prompts at matched settings and the results are scored blind. Speed and completion rate are production telemetry over a rolling 60-day window, not a lab test — they include queue time, because that is what you actually wait. Every engine we measure, including the ones not on this page, is published on the image editor index.
Every image generated here is AI-generated and carries a signed C2PA content credential saying so. Anyone can check a file on verify.
Questions
Which is better, Seedream 5.0 Pro or Wan 2.7 Pro Edit?
On the blind index Seedream 5.0 Pro scores materially higher, and the gap is wider than most pairs in this catalogue. Wan 2.7 Pro Edit is the faster of the two by a large margin at the median.
Do they cost the same?
Yes, both sit at the same credit cost per edited image, which is what makes running the same prompt through both a cheap way to settle a specific job.
How much faster is Wan 2.7 Pro Edit?
Several times faster at the median, measured from submit to finished image on production traffic. Its slow tail runs much further out than its median, so individual edits can take considerably longer.
Which handles reference images better?
Seedream 5.0 Pro accepts the larger number of reference images of the two, which matters when you are giving it several views of the same subject to work from.
Can I use both on the same image?
Yes. Both run in the same image studio on one credit balance, so you can explore with the faster editor and re-run the version you like on the higher-scoring one.
