This online tool uses the same tokenization algorithms as the ones used by the tokenizers of popular large language models (LLMs) like Open AI's GPT-4 and Google Gemini. Choose a model to target. Type or paste the text you want to analyze into the text area and our calculator will automatically calculate the number of tokens in the text. Use these tools to easily count the number of tokens before you send your text to a LLM and make sure you're never over their limit.
To calculate the exact number of tokens for some text, often referred to as a "prompt", you need to give the text to an algorithm, known as a tokenizer, which will break the text into small segments known as tokens. From there, the tokenizer algorithm counts all of the tokens it generates for you. It's important to make sure that you use the right algorithm for the AI language model that you are targeting. Our service offers a token counter for multiple models. The token counter takes all the hard work out of calculating the amount of tokens in a string of text. Simply copy-paste your text into one of our tools above and let us do the hard part for you!
Not all models count tokens the same. Gemini token counts may be slightly different than token counts for Open AI or Llama models. To ensure the best calculation, make sure you use an accurate token counter that will apply a model based token counting algorithm for your specific model. To count tokens for a specific model, select the token counter for the model you want to target.
Many AI models base the cost of using them on the number of tokens sent to the AI and the number of tokens generated in the AI response. These tools help you predict the costs associated with your AI model based on the prompts you provide.
