Token Counter

Estimate the token count for text with various LLM models.

Our LLM token counter helps you understand how large language models like GPT-4o process and bill for text input. By accurately counting tokens before sending requests, you can optimize your prompts, reduce costs, and stay within API rate limits.

How Token Counting Works

Large language models break text into tokens using a process called tokenization. A token can be as small as a single character or as large as a common word. For example, the word "hello" is one token, but a rare technical term might be split into multiple tokens. Different models use different tokenizers, which is why the same text can produce different token counts depending on the model you select. This tool uses the same tokenization algorithms as the actual models to give you accurate counts.

Why Token Counting Matters

Most LLM APIs charge based on the number of tokens processed. Knowing your token count helps you manage costs effectively, especially when working with long documents or generating extensive outputs. Token limits also define the maximum context window a model can handle. By pre-computing token counts, you can split large texts efficiently, avoid unexpected overages, and ensure your prompts fit within the model's context window for optimal performance.

Frequently Asked Questions

What is a token counter?

A token counter estimates how many tokens a piece of text will use when processed by an LLM like GPT-4, Claude, or Gemini. Tokens are the basic units LLMs use to process text.

How do I use the token counter?

Paste your text into the input area and the tool instantly displays the estimated token count for various LLM models, along with approximate cost estimates.

Why do token counts differ between models?

Different LLM models use different tokenizers. GPT models use Tiktoken, while Claude and Gemini use their own tokenization schemes, so the same text may produce slightly different token counts.

How accurate are the cost estimates?

Cost estimates are based on publicly listed API pricing per token. Actual costs may vary depending on your specific API plan, usage tier, or provider discounts.
