Seedream 5.0 Lite Edit vs Wan 2.7 Pro Edit
Seedream 5.0 Lite is the cheapest editor in the catalogue and has so far scored at the top of the blind index; Wan 2.7 Pro Edit costs more per image and scores lower, but comes back sooner and carries hundreds of production edits behind its figures rather than a handful.
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 numbers
| Measure | Seedream 5.0 Lite Edit | Wan 2.7 Pro Edit |
|---|---|---|
| Blind quality index (0–100) | 95 | 84 |
| Median time, submit to finished image | 39 s | 13 s |
| p90 time | 44 s | 78 s |
| Completion rate | 100% | 99% |
| Credits per edited image | 1 | 2 |
| ≈ USD at the best credit rate | $0.19 | $0.38 |
| Production edits behind these numbers | 11 | 807 |
USD is derived at the Premium credit rate of $0.19 per credit and is shown for comparison only. Full prices and the rate every figure derives from are on pricing details. One of these engines has fewer than fifty completed runs in the window, so its timings will still move.
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 Lite Edit costs $1.71 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.

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

A cheaper engine scoring at the top of the index is the kind of result that deserves suspicion rather than a recommendation, and the index marks it preliminary for exactly that reason. It may well hold. It has not yet been tested enough to say.
Wan 2.7 Pro Edit is the opposite kind of row: a mid-range score with enough completed edits behind it that you can plan around the number. It also returns quickly at the median, though its slow tail is long enough that individual edits will occasionally surprise you.
So the pair is really a question about risk. Lite is the cheaper bet on an unsettled number; Wan 2.7 Pro Edit is the more expensive bet on a settled one. For work you have to deliver, the settled number is usually worth the difference.
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 Lite Edit spreads from 39 s to 44 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
The whole case for Lite rests on a score built from very few edits. If that number settles lower as traffic arrives, this pair flips, and nothing published today can tell you whether it will.
Where each one wins
Choose Seedream 5.0 Lite Edit when
- Cost per edit is the binding constraint and this is the cheapest editor available.
- You are iterating on something easy to judge, where a weak result costs only a retry.
- You want the same reference ceiling as the flagship at the lowest price in the catalogue.
Choose Wan 2.7 Pro Edit when
- You want a score with real production volume behind it rather than a preliminary row.
- You want the shorter median turnaround for a queue of edits.
- The work is going to a client and a provisional number is not a basis you want to rely on.
What a real job costs
Six finished images, allowing one reject in three — 9 runs:
- Seedream 5.0 Lite Edit — 9 credits, about $1.71, roughly 6 minutes of queue at the median.
- Wan 2.7 Pro Edit — 18 credits, about $3.42, roughly 2 minutes of queue at the median.
Credits come from a WowMade plan: Start at $25, Go at $60 or Premium at $95 per month. Plans renew monthly until cancelled and can be cancelled online at any time; new purchases are processed by Whop. The full price list is on pricing details.
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
Is the cheapest editor really the highest scoring?
On the blind index so far, Seedream 5.0 Lite sits in the top band at the lowest credit cost. That score rests on very few completed edits and is marked preliminary, so it is an early reading rather than a settled result.
Which of these two is faster?
Wan 2.7 Pro Edit at the median, though its slow tail runs much further out than its typical edit. Both medians are measured on production traffic and published on this page.
Which has more evidence behind its numbers?
Wan 2.7 Pro Edit, by a wide margin. It has hundreds of completed production edits supporting its figures, against a handful for the Lite tier.
How many reference images can each take?
Seedream 5.0 Lite accepts the larger number, matching the flagship tier of its family. Wan 2.7 Pro Edit takes fewer, though still enough for most multi-view edits.
Which should I use for client work?
Wan 2.7 Pro Edit, on the strength of its evidence. For work you have to deliver, a number with volume behind it is a safer basis than a provisional one, even a flattering provisional one.
