LLM token counting: How to estimate and manage costs

By PulseAugur Editorial · [1 sources] ·

Understanding and managing token counts is crucial for efficient use of large language models like ChatGPT, Claude, and Gemini. Tokens, the basic units processed by these models, can be estimated with rules of thumb for English text but vary significantly for non-English languages, code, and structured data. Exact counting can be done using open-source libraries like js-tiktoken for OpenAI models, while other providers offer API endpoints for token estimation. Careful management of input and output tokens, including chat history and prompt instructions, is essential for controlling API costs, which are typically priced per million tokens. AI

IMPACT Enables developers to optimize LLM usage and reduce API expenses by accurately managing token consumption.
