Token counter for GPT, Claude and Gemini

Step 1

Paste or type your text.

Step 2

Pick the tokenizer: o200k for GPT-4o and newer OpenAI models, cl100k for GPT-4 and GPT-3.5.

Step 3

Read the token, word and character counts, and the estimate for other model families.

Is the count exact?

For OpenAI models, yes: the page runs the same o200k and cl100k byte-pair encodings the models use. Claude, Gemini and other families use their own tokenizers, so their numbers are estimates based on the OpenAI count.

How many tokens is a word?

In English, a token is about four characters, so 100 tokens is roughly 75 words. Code, numbers and languages such as Chinese or Japanese use more tokens per character.
