Choosing an image model
Pick an image model id from the catalog. Check that it edits, that it serves 4k, and what it costs, then try your own prompts on a shortlist.
Pick a model id from the catalog and pass it on every request. Three things in the catalog entry decide whether a model can serve your request at all. None of them is a matter of taste:
| Check | Where to look | If the model lacks it |
|---|---|---|
| Does it take images? | img->img in modes, or inputs in supports | 400 validation_error when you send inputs |
| Does it serve 4k? | pricing.per_image["4k"], or 4k in supports | The task fails on a _4k size |
| What does it cost? | pricing.per_image.base, plus per_input | Nothing fails. You pay more than you planned |
Image prices differ by more than two orders of magnitude across the catalog, so check the price before you pin a model.
npx @mynthio/cli models list --type image --capability img2img --4k --max-price 0.05The same filters are on mynth.io/models. --max-price compares
the base price per image.
The catalog does not rank models, and neither do we. Which model looks best depends on your prompts and your taste. Pick two or three in the right price band and run your own prompts through them.
Once you have an id, pass it:
curl https://api.mynth.io/image/generate \
-H "Authorization: Bearer $MYNTH_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"black-forest-labs/flux.2-pro","prompt":"A lighthouse at dusk, 35mm film"}'Do not leave model off to let Mynth choose. That falls back to auto,
which is experimental. The model field
explains why.
