Why the price differs
Both GenRelay and Fal aggregate the same underlying Google model; the difference is markup and billing terms, not model quality. GenRelay's flat $0.02–0.03/image prepaid-balance billing has no per-call minimums or subscription; Fal's $0.0398 is billed per API call under their queue-based system. Output quality and latency should be tested directly for a like-for-like comparison — this page compares list price only.
