How to choose
- Price per imageCheck the price per image for each model at the resolution you need, because prices vary by model and output size.
- Output licence and provenanceCheck the licence on generated images and whether provenance metadata is attached, because an agent publishing images for a client needs clear rights to reuse them.
- Edit and reference inputsCheck whether the model edits an existing image and accepts reference images, since an agent keeping a character or brand consistent across renders depends on both.
- Legible text in imagesCheck how reliably the model renders text in images, because an agent that prints labels or copy onto pictures needs the words to come out readable.
Each one in detail
