You pay for what OneHot reads. A decision is billed by its input tokens, counted with one tokenizer for every size. The models generate no output tokens, and none are billed. Prices are in US dollars before tax, and are paid from prepaid credit. The prices below are our standard list prices, the same since launch on 14 October 2026. There is no contract, commitment or monthly fee: you buy credit yourself in the console. An image is billed as input tokens too: each unique image counts the tokens the model reads for it, 64 to 2,048 by its size, at the price of the model that answers (how images are billed).

​

How each charge works

Dataset storage and teacher labelling show their price before you start. So does every paid job: the console and the API show the price, and max_price_usd refuses a job that would cost more than you agreed (cap a price). These are the standard prices. pricing on GET /v1/onehot gives the prices in force for your account, and GET /v1/models shows which sizes are serving. Your tier, its limits and how credit is held are in accounts and usage.
