What Is SeaArt AI? Stamina, Credits and What Expires

Short version: SeaArt is a community image platform on top of the Stable Diffusion ecosystem, with a usable free tier and paid plans from about $4.79 to $75 a month. It runs two currencies at once. Stamina refills daily and vanishes daily; Credits are bought and kept, and since April 2026 they carry a two-year expiry.

Understanding those two is most of understanding the product.

What SeaArt actually is

SeaArt is a model library with a generator attached, more than a generator with models attached.

The core of the platform is community publishing. Users upload fine-tuned checkpoints and LoRAs, other users generate with them, and the catalogue grows into thousands of styles nobody at SeaArt built. Anime and illustration are heavily represented, which is true of the open ecosystem generally.

That gives it a different feel from a commercial generator. On Midjourney you learn one model deeply. On SeaArt you go looking for the model that already does what you want, which is faster when the style is specific and noisier when you just want a good picture.

Video generation has been layered on since, though the image side remains the reason people are there.

Stamina versus Credits

Two SeaArt currencies, and the difference is worth getting straight before you spend either.

• Stamina — refills automatically every day, valid only for that day, does not accumulate. Free accounts get roughly 130 to 150 daily, about twenty standard generations. Unspent Stamina is gone at reset.
• Credits — bought or earned, and they persist. A standard image commonly costs about six Credits. This is what you draw on once the day's Stamina runs out.

So a day you skip is a day you did not use, and no amount of restraint banks it for the weekend.

The behaviour this rewards is obvious once you see it: burn Stamina first, every day, and keep Credits for work that has a deadline. Most people do the opposite by accident, spending Credits mid-afternoon while a full Stamina bar quietly expires at midnight.

The expiry change nobody announced loudly

Credits used to be permanent. That changed with a cutoff.

Purchased Credits acquired before 1 April 2026 do not expire. Credits purchased on or after that date are valid for two years from purchase. So a balance can now contain two kinds of Credit with different rules, depending on when you bought them.

Two years is not aggressive. Compared with the roughly 90-day clocks attached to some competitors' top-up packs, it is close to generous. It is still a change in the direction every credit system seems to move eventually, and worth knowing before you buy a large discounted pack on the assumption it will keep.

The current rates sit on SeaArt's plan and credit page, and the expiry rule itself is set out in their terms of service, which is the version to trust over any review including this one.

SeaArt pricing

Treat these as approximate. Plan names, discounts, regional pricing, trial availability and included Stamina all move on this platform, more than they do at the commercial end of the market.

Who it suits, and who it does not

SeaArt suits people chasing a specific look. If you want a particular anime sub-style or an illustration treatment that a general model will not produce on request, someone has probably already published the LoRA for it, and using it costs you nothing but Stamina.

It suits experimenters, because the daily refill means tomorrow is always another twenty tries.

SeaArt suits you less if you want one reliable model and no decisions. The abundance is the problem: a thousand community checkpoints of uneven quality is a research project, not a workflow. Commercial generators are worse at niche styles and much better at giving you a good result from your first prompt.

Text rendering is the other gap, as it is across the open ecosystem. Words inside images remain unreliable, which rules out a lot of thumbnail and social work. The Stable Diffusion background explains why that limitation is structural rather than a bug someone forgot to fix.

How the economics compare

Quick flag: Leaxor is mine. Its image side charges per image with no subscription required and no daily reset: Flux 2 Pro, Seedream 4.5 and 37 other models are 1 credit; Nano Banana Pro, Ideogram v3 and Hunyuan Image 3 are 2 credits; GPT Image 2.5, GPT Image 2 and 3 other models are 3 credits, credits at $0.10 each, never expiring. Ten to thirty cents an image, and nothing at all on a month you generate nothing.

Against SeaArt's free Stamina that is not a price argument and I will not make one. Free is free. The trade is what you get for the ten cents: current commercial models rather than community fine-tunes, no style hunting, and a balance that has no clock attached. If you generate a handful of images a month and want them to look a specific way, SeaArt's daily refill is better value. If you generate steadily and would rather not manage two currencies, per-image pricing is simpler.

If the two-currency system is the part wearing you down, the SeaArt alternative comparison covers what a single non-expiring balance changes.

The image generator comparison covers what each commercial model is actually good at, and Perchance is the closest free alternative if you want to skip accounts entirely.

SeaArt video and image to video

Video generation has been added on top of the image platform, and image-to-video is the part worth knowing about.

The pattern that works is the one the platform is shaped for: generate a still using a community model that gives you exactly the style you want, then animate that still. Because SeaArt already holds your image and the model that made it, that hand-off is shorter than moving a file between two products.

Quality sits where you would expect for an open-ecosystem tool. It is not competing with the frontier video models on fidelity, and it does not price as though it is. For animating a specific illustrated style that a commercial video model will not reproduce, being able to start from a community-tuned still is a genuine advantage.

Video consumes the same two currencies as everything else, and it consumes them faster. A day's Stamina goes further on images than on clips.

The community model library, and how to use it

Thousands of checkpoints and LoRAs is the reason to be on SeaArt and the reason people bounce off it.

The failure mode is treating the library as a menu. It is a search problem. A useful approach: find one checkpoint that produces your general look, then layer LoRAs for the specific elements — a character, a lighting style, a rendering technique. That is how the ecosystem is designed to work, and it is why SeaArt can hit styles a general-purpose commercial model cannot.

Two practical warnings. Model quality is uneven because publishing is open, so a highly-rated model is worth more than a promising thumbnail. And a model's own licence may differ from SeaArt's platform terms, which matters if the output is going anywhere commercial.

A related note on content: SeaArt hosts mature-content modes and community models trained on all sorts of material. That is a platform to be deliberate on if you are generating anything that goes out under a brand.

Is SeaArt free?

Genuinely, within limits. Roughly 130 to 150 Stamina a day covers around twenty standard generations, needs no card, and refills tomorrow.

For a casual user that is a complete product. Twenty images a day is more than most people generate. Where it stops is volume, priority in the queue, and any workflow where you cannot afford to wait until tomorrow to finish something.

The paid entry point is unusually cheap at roughly $4.79 a month for the Beginner tier, which is less than a single image costs at some competitors. If SeaArt suits your style needs, the value here is not really in question.

Getting the most out of SeaArt's daily Stamina

Because Stamina resets and Credits do not, SeaArt rewards a particular rhythm, and most people find it by accident weeks in.

1. Spend Stamina first, every day. It expires at reset whether you use it or not. Opening SeaArt to burn the daily allowance costs nothing and banks nothing if you skip it.
2. Explore on Stamina, finish on Credits. Do the wasteful part — the twenty attempts to find a composition — on the currency that disappears anyway. Save Credits for the final render at the settings you actually want.
3. Front-load the week. If a deadline lands Friday, generate on Tuesday, Wednesday and Thursday's Stamina rather than paying Credits on Friday for work three days of free allowance would have covered.
4. Buy Credits in small amounts. Post-April-2026 purchases carry a two-year clock. Two years is generous, but a large discounted pack is still a bet on your own future usage.

Followed properly, this makes SeaArt close to free for most individual creators. Ignored, you end up buying Credits at three in the afternoon while a full Stamina bar quietly expires at midnight, which is the default experience.

SeaArt versus the alternatives

The choice is really between hunting for a style and being handed one. SeaArt is the best option on this list if the style you want is specific and unusual, and the worst if you want a good result from your first prompt without research.

Verdict

Worth it for style-specific work and for anyone who enjoys the model library rather than merely tolerating it. The free tier is real and the paid entry point is cheap.

Check the expiry date on anything you buy after April 2026, and spend Stamina before Credits. Those two habits are worth more than picking the right plan.

Bottom line. SeaArt is the best free-tier image platform for anyone chasing a specific style, and a poor first choice for anyone who just wants a good picture without research. The community library is the entire proposition: it is why SeaArt reaches looks a commercial model will not, and why using it well is a search problem rather than a prompting one. Learn the Stamina rhythm in week one and SeaArt is close to free indefinitely. Ignore it and you will buy Credits you did not need while a full daily bar expires at midnight, which is how most people experience the platform.
