FAQ

What is a token in Large Language Models?

A token is the basic unit of text that a language model processes. It can be a word, a part of a word (like 'ing' or 'pre'), a punctuation mark, or a symbol. For English text, 1 token is approximately 4 characters or 0.75 words. For other languages like Chinese, one character is typically 1-2 tokens. All API pricing is based on the number of tokens in your input (prompt) and the model's output (response).

How are API costs calculated?

The total cost is calculated based on two main factors: the number of input tokens and the number of output tokens. Most models have different prices for input and output. The formula is:

Cost = ( (Input Tokens / 1,000,000) * Input Price ) + ( (Output Tokens / 1,000,000) * Output Price )

This gives you the cost for a single API call. Our calculator multiplies this by the number of calls you specify.

How can I monitor and control my API costs?

Every AI provider offers a dashboard where you can track your usage and spending. It is highly recommended to set up billing alerts and usage limits to avoid unexpected charges.
