Token Estimation Guide

How it works:

  • English text: ~1 token per 4 characters
  • Code/symbols: ~1 token per 3 characters
  • Non-English languages: ~1 token per 2-3 characters
  • Numbers and punctuation: variable, typically higher token density

Note: This is an estimation. For precise token counts, use the actual model's tokenizer (OpenAI's tiktoken, Anthropic's tokenizer, etc.).
