Estimate token counts and API costs for GPT-4, Claude, and Gemini.
Estimate token counts and costs for popular AI models including GPT-4, Claude, and Gemini.
Tokens are the basic units that AI models use to process text. A token can be a word, part of a word, or a punctuation mark. On average, one token is about 4 characters or 0.75 words in English.
AI API providers charge based on token usage. Knowing your token count helps you estimate costs, optimize prompts, and stay within model context limits.
Our estimates use standard tokenization ratios for each model family. While exact counts may vary slightly from the actual API, our estimates are typically within 5-10% accuracy.
