I generated her once, on the first try, and she looked exactly right. Then I tried to bring her back in a different scene and she was gone.
The face had drifted and the hair colour was roughly correct but the scar through her eyebrow had vanished, the expression had reset to something generic, and the specific quality that made her feel like a real person rather than a placeholder had quietly disappeared between one generation and the next.
That is the problem this comparison is actually about.
Both SeaArt and PixAI produce attractive anime images, and you can confirm that in the first ten minutes on either platform. What takes longer to discover is whether the character you built on Tuesday still looks like herself on Thursday and that question is what separates these two platforms more than anything else in their feature sets.
I tested both using the same character across the same four tasks. The character was a night-market vendor: late twenties, long dark auburn hair in a loose braid, pale green heavy-lidded eyes, a faint scar through her left eyebrow, a moss-green linen apron over a cream blouse.
On PixAI I used Tsubaki.3, which launched September 16, 2026.
I gave myself six specific details to track across every output and ran both platforms through the same sequence: portrait, complex scene, two continuation scenarios, and two rounds of sequential editing.
What I found was that one platform is better at generating images and the other is better at building characters, and those are genuinely different things.
SeaArt vs PixAI: What Are We Comparing?
Most platform comparisons start with a feature list. This one starts with a workflow question, because that is what actually determines which one you should use.
If you generate images and move on, both platforms will serve you. If you generate a character and then need her to show up again with the same face, same scar, same quality of expression, the gap between these two platforms opens up fast.
On PixAI I used Tsubaki.3 exclusively, free tier for generation, which provides 10,000 credits daily through the check-in system. All generations were 2K resolution.
On SeaArt, I tested using one of its dedicated anime models, also free tier, which allows 21 image creations per day with a daily reset. Same resolution target. Prompting style adapted to match what each platform is actually built for.
SeaArt produces strong atmospheric images. Tsubaki.3 produces a character you can keep working with. Whether that distinction matters depends entirely on what you are making.
Anime Image Quality: Creating the Same Original Character
The character I built for this test was someone I thought of as a night-market vendor.
“A girl in her late twenties. Long dark auburn hair worn in a loose braid over one shoulder, a few shorter pieces escaped at the front. Pale green eyes, slightly heavy-lidded, the kind of face that looks like it is permanently on the edge of saying something dry. A moss-green linen apron over a cream-coloured blouse, sleeves pushed to the elbows. A small silver ring on her right index finger. A faint scar running through her left eyebrow.”
Six trackable details: the braid, the eye colour, the apron, the scar, the ring, and the expression quality. Every generation either held them or it did not.
On PixAI with Tsubaki.3
I described her the way I would describe her to someone who had never seen her. The model committed fully to an anime illustration style, and the braid came back held loosely near her chin, a pose that does real work for the expression. The pale green eyes were the standout result here, heavy-lidded and slightly narrowed, looking off to the side with exactly the composed, sardonic quality I was after, this is the closest either platform got to the character's actual temperament. The olive-green apron sat correctly over the cream blouse, sleeves pushed to the elbows. The silver ring was clearly visible on her hand, no ambiguity to it. The scar through the left eyebrow did not survive, the brow reads clean.
On SeaArt
The first result did not read as a character illustration at all. SeaArt returned a photorealistic image, closer to a photograph than a drawing, which nothing in the prompt asked for. The braid held, though the hair came back a brighter copper-red rather than the dark auburn described. The moss-green apron over the cream blouse was accurate, sleeves pushed up as specified, with an adjustable shoulder strap buckle the prompt never mentioned but did not contradict either. The pale eyes were present, but the expression missed, what came back reads as blank or somber rather than dry and composed. The scar through the left eyebrow did not survive. The ring did not survive either, her hands aren’t exactly visible.
How Well Does Tsubaki.3 Follow Detailed Anime Prompts?
For the complex scene test I put the character behind the stall at the night market itself. I wanted her leaning across a low wooden counter, one hand flat on the surface and the other lifting a small glass lantern toward a customer whose face was not visible. Just a hand reaching into frame from the right edge. String lights overhead, blurred and warm. Steam rising from something off to her left. Her expression focused, slightly transactional.
Seven simultaneous requirements: the character, a specific interaction gesture, a partially visible second figure, a prop held in a specific hand, environmental lighting from two sources, an atmospheric element, and an expression quality. The Tsubaki.3 prompt guide recommends structuring descriptions to cover character, scene, pose, clothing, lighting, camera angle, and mood. That framing held here.
Prompt used on Tsubaki.3:
“A young woman with a long dark auburn braid, loose pieces at the front, pale green heavy-lidded eyes, faint scar through her left eyebrow, wearing a moss-green linen apron over a cream blouse, sleeves pushed to elbows, silver ring on her right index finger. She is standing behind a low wooden market stall counter, leaning forward, left hand flat on the counter, right hand raising a small glass lantern toward a customer. Only the customer's hand is visible, entering from the right edge of the frame. String lights hang blurred and warm overhead. Steam rises from something off to her left. Her expression is focused and slightly transactional. Night market setting, warm ambient light, soft bokeh background, detailed anime illustration style, 2K.”
The result held most of this. The counter, the lean, the lantern in the right hand, all of it landed. A small portion of the customer's hand is visible entering from the right edge of the frame, exactly where the prompt called for it, fingers reaching toward the lantern rather than a full figure intruding into the shot. The string lights overhead read as warm and blurred. The steam appeared correctly near her, faint but present. The scar through the left eyebrow carried over this time, holding up better than it did in the portrait test. The expression landed as focused but leaned cautious rather than transactional, close, but her own editorial call about it.
The braid was accurate, and the ring did show up this time, a clear band visible on the hand raising the lantern, breaking from the pattern set in the portrait test. The left hand on the counter is flat against the wood, fingers spread, matching the instruction rather than hovering above it.
On SeaArt with the same concept adapted to tag-style prompting, the atmosphere landed well: string lights, warm bokeh, a colourful market backdrop with figures blurred in the distance. The scar and ring both showed up in this scene, so unlike the portrait test, both platforms held those details here.
What was missing was the spatial logic: the lantern sits raised near her own side rather than extended toward where the customer's hand is reaching, so the handoff reads as two things happening in the same frame rather than one gesture between them. The expression edged toward a glare rather than the low-key, businesslike read the prompt asked for.
Can You Keep the Same Character Across Different Scenes?
I reused the character in two additional situations on each platform.
First: early morning, before the market opens. She is sitting on an upturned crate in an empty lane, a ceramic mug held in both hands, looking at nothing in particular. No apron. The braid slightly undone from sleep. The expression unguarded for once.
Second: a rainy afternoon in the small backroom of her stall. Standing at a wooden shelf, back to camera, reorganising jars and small wrapped bundles by colour. Grey light through a narrow window.
On Tsubaki.3 I used text alone for both. The PixAI character consistency guide covers the reference-based approach for tighter control. I used text-only here specifically to test what the model holds from description alone.
Morning scene — Tsubaki.3
The character held reasonably well, but not everything did. The braid came out looser, matching the request, but the eyebrow scar did not carry over here, the brow reads clean on both sides, a miss in a scene where the description specifically asked for the same person off-duty rather than a different rendering of her. The apron was correctly absent, replaced with dark trousers and a loose white shirt. She's holding the ceramic mug with both hands as instructed, steam rising from it, sitting on the crate with her legs visible and one foot bare at the frame's edge. The expression is close to what was asked for, quieter and more unguarded than the market-stall version, though it still carries a faint wariness rather than reading as fully open.
Backroom scene — Tsubaki.3
This is where text-only consistency showed its ceiling. The hair was still correct, the auburn braid recognisable. But with the face largely in three-quarter-from-behind partial view, the details that carry identity were mostly hidden. The shelf, the jars, the grey rain light from the narrow window all came through cleanly. The limitation here is angle, not model quality.
On SeaArt
On this SeaArt regeneration, the character held far better than the earlier attempt. The hair is back to the correct dark auburn, and the eyes are pale green, matching the original description, no color drift this time. The braid is present, loose and undone at the front as the morning scene called for, and the scar through the left eyebrow is clearly visible, unmissable this time rather than obscured. The apron is correctly absent, replaced with a cream button-up shirt. She's holding the mug in both hands, steam visible rising from it, seated on the crate with dark trousers visible below the knee.
The one place this drifts from the original description is setting and expression: the market-stall backdrop is gone entirely, replaced with an open road and a sunrise, and the expression reads as more pointed and alert, narrowed eyes with a sharper focus, rather than the unguarded, half-awake quality the "early morning, before the market opens" prompt was going for. Placed next to the earlier SeaArt portrait, this is recognizably the same character, hair, eyes, scar, and braid all consistent, even though the mood and location depart from what was actually asked for.
The backroom scene was SeaArt's strongest result across the whole test, though the face is fully visible here rather than back-to-camera as the prompt specified. The character held clearly: dark auburn hair, pale green eyes, the scar through the left eyebrow sharp and unmistakable, the braid correct, the ring visible on both hands. She is standing at a counter with empty hands rather than reorganising jars on a shelf, but the atmosphere carries the mood well regardless, muted grey-green light, glass jars stocked behind her, warm wood tones, grey rain light through the window.
The pattern across both platforms: Tsubaki.3 holds close-range facial consistency better. SeaArt holds atmosphere regardless of angle. For a character who needs to be recognisable face-to-face across scenes, text-only Tsubaki.3 is the stronger starting point.
Editing an Existing Image with Tsubaki.3
I took the night market scene and ran it through two sequential changes in PixAI Studio. PixAI Studio is the workspace. Tsubaki.3 is the model performing each operation.
First edit: lighting shift
Instruction: Remove the string lights. Make the scene lit only by the glass lantern she is holding. Increase the darkness at the edges of the frame. Keep everything else exactly as it is.
The string lights disappeared. The lantern became the primary light source, and the model handled the logic of it correctly. A warm pool on her face and the counter, the rest of the frame falling off into dark. Character details held: the braid, the apron, the scar, the expression. The customer's hand at the right edge remained. The counter surface became slightly less distinct in the lower light, which made sense physically even if I had not asked for it.
Second edit: expression
Instruction (taken from the lighting-edited result):
Soften her expression. She has just heard something that surprised her pleasantly. Not quite smiling yet, but close. Keep her eyes the same direction, keep everything else where it is.
The eyes stayed in the same direction, which was the instruction I was most concerned about. The expression shifted. The set of the mouth changed, a softness that was not there before. The scar became slightly harder to read in this version, the changed facial muscle position reading differently under the lantern light. Not gone, but less distinct than in the first edit.
The second edit built on the first rather than resetting it. That is the thing that impressed me most. Each change held what came before it.
On SeaArt
On SeaArt, I ran a comparable edit using inpainting on the face region. The expression changed to a warm, open smile with visible blush, a full swap from the composed, sardonic quality the character was built around. The scar disappeared. The eye colour shifted to a warm brown-red, a clear break in continuity on a detail that had held consistently until this point.
Everything outside the face carried over cleanly: the braid, the ring, the apron, the market backdrop, the lantern, and the customer's hand all remained correctly placed. The limitation was squarely the face: eye colour drift and a full expression change together make this the weakest identity match of the SeaArt set, closer to a different character wearing the same outfit than an edited version of the same person.
Free Access, Credits, and Practical Limits
On PixAI, the daily credit check-in delivers 10,000 credits. At 2K resolution with Tsubaki.3, a standard single-image generation costs roughly 4,000–4,400 credits depending on image size. Additional credits are available through missions and community activity. LoRA training is included on the free tier.
On SeaArt, the free tier allows 21 image creations per day. Stamina resets each day and does not accumulate, though credits purchased after April 1, 2026 can be saved for up to two years. The anime model I used did not require a paid upgrade. I hit a queue wait on one generation during peak hours, which added time but not cost.
The practical split: PixAI's free tier supports the full generation workflow including LoRA training, but the editing tools that matter most for continued creation sit behind the paywall. SeaArt's core generation loop is more fully accessible for free.
SeaArt vs PixAI: Which Should You Choose?
Consider PixAI with Tsubaki.3 if…
You're building something where the same character needs to hold up across more than one image, and honestly, that's the whole reason I ran this test in the first place. The natural language workflow removes a lot of the front-loading tag systems demand, I found myself just describing her the way I'd describe her to a friend, and that alone changed how the results came back. If your work involves expression sheets, sequential appearances, or anything closer to continued creation than standalone illustration, this is genuinely where the platform earns its keep.
SeaArt may suit you if…
Atmosphere and environmental quality matter more to you than strict character precision, or you are already comfortable in a tag-based workflow with patterns you trust, or you need the full generation loop for free. The anime output quality is genuinely strong and some of the lighting and mood work here was the best of the whole test. The limitation I kept running into was not the first image, it was everything after it.
These are not platforms competing for the same user. They suit different phases of a creative process. If you are generating standalone illustrations, SeaArt holds its own. If you are building a character you need to live with across multiple scenes and edits, Tsubaki.3 gave me more to work with, and it showed every time I came back to her.
