About Token Counting
What are tokens?
Tokens are chunks of text that language models process. They can be words, parts of words, or even punctuation. Most models tokenize text into smaller pieces - roughly 1 token per 4 characters in English.
- Common words like "the" or "is" are usually 1 token
- Longer words may be split into multiple tokens
- Spaces and punctuation count as separate tokens
Why count tokens?
- API costs: Most AI services charge per token
- Context limits: Stay within model capacity
- Optimization: Reduce costs by trimming prompts
- Planning: Estimate costs before deploying
Note: This tool uses the same tokenization libraries as OpenAI's models. For Claude and Gemini, counts are approximate but very close to actual values.
