What our research says

Astria

Astria is the plumbing a lot of AI-headshot and virtual-try-on products are quietly built on. Buy it if you are shipping a subject-consistent image feature; skip it if you just want ten headshots of yourself, where a packaged consumer app is cheaper and far less work.

Pros

priced per fine-tune and per generation, with no subscription floor
a free mock mode lets you test the integration end to end without spending
auto top-off refills the balance so production API calls are not interrupted
subject consistency is the core competence, not a bolt-on feature

Cons

you pay for every training run, including the ones that come out wrong
output quality depends heavily on input photo selection and prompt craft
with no monthly plan, cost forecasting means modelling call volume yourself
the marketing site now targets fashion and ecommerce, so general users get less guidance

Leonardo.Ai

Leonardo is the generator to pick when you need control over the model rather than one house style, and it is the only major one with a real API and custom training. Token accounting is the tax you pay for that flexibility.

Pros

Large library of fine-tuned model presets instead of a single opinionated model
Custom model training on your own images is available without an enterprise contract
A genuine documented API, which the obvious competitor still does not have
Free tier of 150 daily tokens is enough to evaluate properly

Cons

Token costs differ by model, resolution and feature, so per-image cost is hard to predict
150 free tokens go in roughly ten generations
Concurrency and queue position are tier-gated, so cheap plans wait
Roadmap now serves Canva's product priorities, not standalone power users

Which one fits

Choose Astria if you need

developers building headshot, avatar or try-on products on someone else's training stack

studios that need one face to stay consistent across a whole campaign

Choose Leonardo.Ai if you need

Game and product teams that need consistent assets from a fine-tune they control
Anyone who wants generation, canvas editing and upscaling in one place
Developers who need image generation behind an API rather than a chat window
Users who want to train a model on their own reference set
