How It Works

Large Language Models (LLMs) process text using tokens, which are chunks of text such as words, characters, or punctuation. The number of tokens determines both the cost and the limits of what you can send to a model.

  • Tokens vs Words: Tokens are usually smaller than words. For example, "ChatGPT" may count as two tokens: "Chat" and "GPT".
  • Cost Calculation: Each model has a price per 1M tokens. We calculate your cost on the backend.
  • Input vs Output Tokens: You are billed for both the text you send (input) and the text the model generates (output). This tool estimates input costs only.
  • Model Differences: Advanced models like GPT-5 cost more per token but are more powerful. Smaller models are cheaper and faster.

Use this tool to estimate costs before running large prompts. Always check the official provider’s documentation for the latest pricing.
