About Token Counting

Token counting is essential for working with large language models (LLMs) like GPT-4, GPT-3.5 Turbo, and Llama. Each model has a specific token limit, and understanding how many tokens your text uses helps you:

  • Stay within model context limits
  • Optimize API costs (as many providers charge per token)
  • Improve prompt engineering by understanding token efficiency
  • Debug issues related to context length
