FAQ
What is a token?
A token is a chunk of text that LLMs process. It can be a word, part of a word, or a punctuation mark. On average, 1 token ≈ 4 characters in English or ≈ 0.75 words.
Why do token counts differ between models?
Different models use different tokenizers. GPT-4o uses the o200k_base tokenizer while Claude uses its own. The same text may produce different token counts across models.
How accurate is this counter?
For OpenAI models, we use the official tiktoken tokenizer — 100% accurate. For other models (Claude, Llama, Gemini), we use calibrated estimates that are typically within 5% of the actual count.
