Generative AI platforms and model APIs compared, side by side
Each page here puts two model APIs or two serving stacks side by side on the same questions: what the publisher states about price, data use, retention, model lifecycle and exit, and what running the model yourself changes. Every fact links to its source and carries the date it was read.
