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
  • $20 of credit on API-key creation is a real evaluation budget
  • 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
  • ecommerce teams needing the same garment or product across many generated shots
  • 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
