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

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 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

Plan	Approx. monthly	What it is for
Free	$0	~130–150 Stamina daily, no card
Beginner	~$4.79	Casual use beyond the daily cap
Standard	~$15	Regular generation
Professional	~$30	Heavy use, faster queues
Master	~$75	Volume work

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

It 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.

It 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 and no daily reset: HiDream and Flux 2 Pro at 1 credit, Seedream 4.5 and Recraft v4 at 2, Imagen 4 Ultra at 3, 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.

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.

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.
