Helicone 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 90 models on this page. Coverage spans text and chat (87) and classification and safety (3). The lowest-priced model hosted here is Llama Prompt Guard 2 22M.
Helicone is the lowest paid channel for 12 models that have at least two competing paid hosts, which is where its pricing genuinely leads rather than being the only option.
