What are tokens? Tokens are the basic units of text that Large Language Models (LLMs) process. They can be words, parts of words, or even individual characters.
Token Counts by Language:
- English: ~4 characters per token
- Latin-based: ~3.8 chars per token
- Chinese/Japanese: ~1.5 chars per token
- Thai/Arabic: ~3 chars per token
Example Tokenization:
"Hello world" → ["Hello", " world"]
"tokenization" → ["token", "ization"]
Note: These are approximations based on average token sizes. For exact counts, model-specific tokenizers should be used.
