What is tokenisation?

Tokenisation converts text into smaller units a model can process.

Try this yourself

Compare "hello", "Hello!" and "नमस्ते" with the same tokenizer. Explain why character length alone does not determine token count.

Check your understanding

The same text can produce different token counts for different tokenizers. You must specify the tokenizer when reporting a count.

A mistake to avoid

Do not assume one token equals one word, especially for multilingual text, URLs and code.

Before looking at the answer, write a short explanation and one example of your own. Finish by naming one limitation of the method. Use Mark as read when you are ready, or return to the previous lesson if a term is unclear.
