Token: A token represents a common sequence of characters. The number of tokens used for each English character may vary. For example, a single character like “antidisestablishmentarianism” might be broken down into several tokens, while a short and common phrase like “word” might use just one token. Generally speaking, for a typical English text, 1 token is roughly equivalent to 3-4 English characters. The exact number of tokens generated by each call can be obtained through the Token Calculation API.Billing Logic
Chat Completion API charges: We bill both the Input and Output based on usage. If you upload and extract content from a document and then pass the extracted content as Input to the model, the document content will also be billed based on usage. File-related interfaces (file content extraction/file storage) are temporarily free. In other words, if you only upload and extract a document, this API itself will not incur any charges.Model Pricing
