How to choose

Start with non-negotiables: audio, resolution, references, latency and commercial workflow. Then compare cost per accepted output rather than cost per attempt. A model that needs fewer retries may beat a cheaper headline rate.

Why these rankings can change

Model versions, promotional rates and provider routing change quickly. Each underlying profile includes its source and review date; stale entries are removed from rankings until rechecked.
