When one platform beats another across 8 tests, the useful question isn't which won. It's whether the wins share a cause.
In this case most of them do. One behaviour, reproducible on two separate models, accounts for the four largest score differences in the set. The tests where that behaviour doesn't apply produce scores within 1.5 points of each other, and on two of those the losing platform followed my instructions more closely.
So this SeaArt vs PixAI write-up is a trace rather than a review. Isolate the behaviour, reproduce it, show where it propagates, then show where it doesn't.
Setup
PixAI: Tsubaki.3 for all 8 tests, edits run in PixAI Studio.
SeaArt: Z Image Turbo for the character, the 80s scene and the first continuation. Nova Anime AM for the second continuation, both edits, the action shot and the close-up.
Accounts: free on both sides.
Scoring: out of 10, weighing instruction adherence, anatomy, style match, and whether the output was usable as it stood.
These results come from the models I chose. Both host larger catalogues, so a different SeaArt pick could produce different numbers.
The baseline: both platforms make the character fine
Before isolating anything, a control. Can each platform produce the subject at all?
Method: new generation on both platforms, text only.
Soft anime illustration of a young woman arranging flowers behind the counter
of her tiny flower shop in the morning. Long silver braid over one shoulder,
green eyes, a black apron with a white peony pinned to the strap. Buckets of
tulips and roses around her, sunlight pouring through the front window, a calm
little smile.
PixAI 8.5. Silver braid, green eyes, black apron and white peony all present, with sunlight pouring through the window onto buckets of tulips and roses and a soft calm smile. She holds yellow sunflowers that weren't requested, one finger renders a little long, and her other hand hides behind the stems. Her face and hair are clean and distinct, which matters for the reuse tests.
SeaArt 6.5. Braid, eyes, apron and peony also present. It followed the flower list more closely, with tulips on one side and roses on the other and nothing extra. Shading is flat and her fingers blend into the rim of the bucket she's holding.
A 2-point difference on detail and lighting, with SeaArt ahead on literal instruction following. Nothing here predicts what follows.

Isolating the behaviour
Both platforms let you set an image as a reference. I used each platform's own baseline image as its reference, so neither was working from unfamiliar source material. The character consistency guide documents this method on the PixAI side.
PixAI reference setup (Left), SeaArt (Right)
Method: reference-based on both platforms, each using its own baseline image.
The same young woman from @image1 running through heavy rain with a big
bouquet hugged to her chest, laughing, a clear umbrella tilted over the
flowers instead of herself. Keep her long silver braid, green eyes and the
black apron with the white peony. Wet city street, reflections on the
pavement.
PixAI 8.8. Identity held, with green eyes, silver braid, black apron and the peony near the strap. She laughs open-mouthed hugging a colourful bouquet. The rain reads wet: droplets on her skin, damp blouse, reflective pavement, and the clear umbrella showing its ribs. Fingers on the bouquet are clean. Its miss: the umbrella is over her head rather than tilted over the flowers.
SeaArt 1. It returned the baseline image. Same shop, same counter, same pose, same indoor light. No rain, no umbrella, no running.
The behaviour, stated precisely: the reference image outweighed the entire prompt. Not partially. The prompt contributed nothing detectable to the output.
Left PixAI. Right SeaArt.
Reproducing it on a second model
A single failure could be a model quirk, so the second continuation test doubled as a model control.
Method: reference-based on both platforms. Z Image Turbo first on SeaArt, then Nova Anime AM.
The same young woman from the @image1 sitting on the back step of her flower
shop late at night, eating a rice ball, tired but smiling. Keep her long
silver braid, green eyes and the black apron with the white peony. Fairy
lights strung above the door, empty buckets beside her.
Scene 2, Image Generation Panel: PixAI (Left), SeaArt (Right).
PixAI 9.2. She's on the back step holding a rice ball in both hands with a calm tired smile, fairy lights over the door, empty buckets beside her, dark tones reading as late night. Her grip looks natural, warm light falls on her hair and face, and braid, eyes, apron and peony all match.
SeaArt, Z Image Turbo: returned the baseline image again. Same behaviour, second prompt.
SeaArt, Nova Anime AM: 2.5. Yuna's look held with a sleepy smile, and then she stands at the counter rather than on the back step, in daylight rather than at night. A small dish of rice rests beside her untouched, the buckets are still full of flowers, and fairy lights appear in the window while the daylight dominates.
Two models, same class of result. That points at how SeaArt handled the reference image in my setup rather than at any single model.

Where the behaviour propagates: chained edits
Edit chains are the same problem in a different shape, since each step has to inherit state from the last one.
On PixAI I opened PixAI Studio and chained the baseline image into two edits, with Edit 2 running on the Edit 1 result. Studio holds the steps together; Tsubaki.3 does the editing. The PixAI Studio tutorial covers building these chains.
PixAI Studio the first image, Edit 1 and Edit 2 connected in a chain.
Method: edit, run on the baseline image.
Change her black apron to a soft pink apron, keeping the white peony pinned to
the strap. Keep her face, braid, pose and the shop the same.
Method: edit, run on the Edit 1 result.
Turn it into a snowy winter evening: snow falling outside the window, warm
lamp light inside the shop, frost on the glass. Keep her, the pink apron and
the peony the same.
PixAI Edit 1: 9.5. Apron changed from black to soft pink with the peony and its green leaf in place, and face, braid, pose, flowers and lighting unchanged.
PixAI Edit 2: 9.8. Bright morning became a snowy evening with snow outside and frost spreading across the glass, lit by a warm lamp. The pink apron and peony carried through from Edit 1, with the flowers inside still fresh under the new light.
Left to right: the first image, Edit 1, Edit 2, all Tsubaki.3 in PixAI Studio.
SeaArt Edit 1: 9. Apron changed to pink, peony kept, face, braid, pose and shop all preserved. Within half a point of PixAI, which is the important detail here: the first edit is not where SeaArt has a problem.
SeaArt Edit 2: 4. It built a good winter scene, with snow outside, frost on the glass and warm lamp light. The apron went back to black. It kept her face and the peony and discarded Edit 1's change entirely.
Left: SeaArt Edit 1. Right: SeaArt Edit 2, with the apron back to black
Same root cause, different surface. A single reference produced a good result on SeaArt. A chained one dropped the inherited state. The behaviour is about what the platform treats as the source of truth when a reference and an instruction disagree.
Where the behaviour doesn't apply
Three tests need no reference at all, and the scores tighten considerably.
80s paper airplane scene
Method: new generation on both platforms, text only. Landscape 16:9 selected in the size selector.
80s city pop anime style. A girl leans out of a moving train window at sunset
and throws a red paper airplane to a boy on a bicycle riding alongside the
tracks, who reaches up to catch it. Low angle from the grass beside the
tracks, palm trees and a pink and purple sky behind them, lens flare from the
setting sun.
PixAI 8.5. Bold cel shading, bright colour and sharp retro lines matching 80s city pop. The low angle from the grass, palm trees against the pink and purple sky, and the lens flare all present, with the girl leaning out and the red plane between them. Train, wheels and bicycle drawn cleanly, boy riding beside the tracks. Its miss: the boy keeps both hands on his handlebars rather than reaching for the plane.
SeaArt 7. It got the action right, with her throwing and him reaching up with one hand, plus the 80s look in warm light and vintage colours. Its problems are spatial: the paper plane is huge next to both of them, the boy rides on the railway tracks rather than beside them, and the girl leans out of an open door with nothing holding her, so her lower body floats outside the train.
Instruction following favours SeaArt. Scene coherence favours PixAI. That split is one to keep in mind.
PixAI Generation (Tsubaki.3)
SeaArt Generation (Z Image Turbo)
The Tsubaki.3 prompt guide covers prompt structure on the PixAI side.
Sakuga action shot
Built to be hard: two characters, contact between them, extreme perspective, heavy lighting.
Method: new generation on both platforms. Prompt Helper enabled for this test only on PixAI.
High-octane anime action scene in modern Sakuga style. Low-angle fisheye lens
view looking up from the street. A female cybernetic warrior in dark techwear
dives downward mid-air, wielding a glowing blue katana with motion blur. Below
her, a male enforcer blocks the blade with an orange translucent energy
shield, causing electrical sparks to scatter across the pavement. Rain-slicked
alley with wet reflections and flickering neon signs in cyan and magenta.
Dynamic lighting, dramatic shadows, extreme foreshortening on the diving
character outstretched hand.
PixAI 9.6. The fisheye curve bends the alley walls outward, and her outstretched hand reaches straight at the camera with the fingers and glove still correct under that distortion. The katana strikes the top of the orange shield, he crouches below in a steady block, and sparks spray from the contact point, with cyan and magenta neon lighting the upper frame and the wet street reflecting shield and signs.
SeaArt, Nova Anime AM: 5.5. Lines and shading are crisp and the neon reflects well in the puddles. She crouches on the ground rather than diving, there's no hand reaching at the camera, her sword strikes the pavement rather than his shield, and his orange light points away from her. Both figures end up on one level, which drains the shot of any vertical drama.
I also ran this on PixAI's older Tsubaki.2 out of curiosity. That run also handled the dive, the blade meeting the shield and the foreshortened hand, with very sharp linework.

Emotional close-up
Two faces, joined hands and a tear in one tight frame.
Method: new generation on both platforms, batch of four.
Anime key visual, close-up of a young couple saying goodbye on a train
platform at dusk. She presses her forehead against his, eyes closed, a single
tear on her cheek, their fingers interlocked between them. Warm backlight from
the setting sun, the train doors open behind them, soft lens flare.
PixAI 9.5. Their fingers weave together properly, with the right count and aligned knuckles. A thin line of light runs between their foreheads so the faces stay separate, and the tear on her cheek picks up light from the train door. Soft painterly light and a muted dusk sky give it a film-like feel.
SeaArt 7.5. Faces stay separate where they touch, the tear is present, and the open train doors frame them against the sunset. Their hands hold in a normal grip rather than lacing fingers, though every finger is correct.
Left: PixAI. Right: SeaArt.
Scorecard
| Test | PixAI (Tsubaki.3) | SeaArt |
|---|---|---|
| Original character | 8.5, better lighting and detail | 6.5, followed the flower list |
| 80s paper airplane | 8.5, scene makes sense, no reach | 7, right pose, wrong scale |
| Rain scene from reference | 8.8 | 1, returned the reference |
| Night scene from reference | 9.2 | 2.5, wrong pose and time |
| Edit 1, apron | 9.5 | 9 |
| Edit 2, snow | 9.8, kept the pink apron | 4, apron went back to black |
| Sakuga action | 9.6 | 5.5, no dive, no contact |
| The goodbye | 9.5, laced fingers | 7.5, normal grip |
| Cost per image | 4,500 to 7,200 credits | 8 stamina, 15 per edit |
| Free daily allowance | 10k credits, about two images, 12k free daily credits for paid members | 130 stamina, about 16 images |
Group those rows by whether a reference or an inherited edit is involved and the pattern resolves. With one: differences of 7.8, 6.7 and 5.8 points. Without one: 2, 1.5, 4.1 and 2 points, and SeaArt's single first-pass edit within half a point.
Cost
PixAI: price scales with output size. In my runs that meant 4,500 credits at 768 × 1280, 5,300 for a 3:5 image in PixAI Studio, 5,500 at 1104 × 1824, and 7,200 for a single image made from a reference. A free account receives 10,000 credits daily, which funds roughly 2 Tsubaki.3 images. Other earning routes are listed in the free credits guide.
SeaArt: charged in stamina, priced per model. A single image cost 8 stamina, an image from a reference also 8, and an edit was estimated at 15. Free accounts get 130 stamina a day, about 16 images or around 8 edits. The cheapest paid plan, Beginner, is $5.99 a month for an extra 300 stamina a day, which SeaArt puts at roughly 1,125 images a month, with plans up to $149.99.
Stamina and credits measure different things, so there's no conversion between them. Images per free day is the one figure that transfers, and SeaArt supplies considerably more of them.
Effort runs the other way. SeaArt cost me a model switch purely to rule out a model-specific cause, and even then no new scene emerged from a reference. PixAI needed one model for all 8 tests.
Conclusion
The trace is clean. One behaviour, reproduced on two models, explains the three largest score differences and propagates into a fourth through the edit chain. Remove it and the two platforms sit within a couple of points, with SeaArt ahead on literal instruction following in 2 of the 3 remaining tests and far ahead on free volume.
That makes this anime AI generator comparison a question about your workload rather than about output quality. Single images: the platforms are close and SeaArt gives you eight times more of them free. Anything where the same character has to survive a second generation: PixAI was ahead in every test I ran.
For anyone evaluating a SeaArt alternative specifically for character reuse and chained editing, Tsubaki.3 did more of what I asked here. Framed the other way, PixAI vs SeaArt on single-image work is closer than the scores suggest, and the free allowance may matter more than the point difference.
