Long words\nare broken up into several tokens. The set of all tokens used by the model is\ncalled the vocabulary, and the process of splitting text into tokens is called\n*tokenization*.\n\nFor Gemini models, a token is equivalent to about 4 characters.\n100 tokens is equal to about 60-80 English words.\n\nWhen billing is enabled, the [cost of a call to the Gemini API](/pricing) is\ndetermined in part by the number of input and output tokens, so knowing how to\ncount tokens can be helpful."]]
