Serverless API over open models, whose Free plan grants $1 of credit every four weeks for open models of up to 7B parameters, one request at a time, with no billing
The page this row is verified against names no free model, so the column stays empty; callable ids, where the row has them, are under Connect.
The billing page’s Free card reads “$0 / month - Get $1 in free credits”, “Run open models up to 7B parameters”, “1 concurrent request (open models)” and “Credits refresh every 4 weeks”, and the billing cycle adds that “Credits expire 4 weeks after grant”, with no billing on the plan. The card also lists “Access all closed model providers”, but the get-started guide says a closed-source model needs “an account with the model provider” and is “billed directly by the provider”, so the free dollar reaches only the open models of 7B parameters or fewer — Qwen3 4B, the docs’ own example, is one. An open model above 7B needs at least $10 of credit bought in the last four weeks, on the $3 a month plan. Read 2026-09-17
