ZenMux is a third-party gateway that routes to many upstream models through one API. Gateway quotes are often among the lowest on the site, but availability, rate limits and routing can vary between models, so a low headline price is worth verifying against your own workload.
It lists 129 models on this page. 119 of them have a public price. 6 are offered at $0. Coverage spans text and chat (125), image generation (2), and speech and audio (2). The lowest-priced model hosted here is GLM-4.6V-Flash.
ZenMux is the lowest paid channel for 11 models that have at least two competing paid hosts, which is where its pricing genuinely leads rather than being the only option.
