Calculate the number of tokens for any phrase or document on any popular LLMs
Disclaimer: These token calculations are an estimate. Please refer to the respective models’ documentation for a more precise calculation.
Using our token calculator, you can:
As our calculator supports multiple models, you can get a full picture of how different Large Language Models (LLMs) handle tokens. This also means that the number of tokens in a single phrase or sentence varies from one model to another.
Advanced Conversational Intelligence
While we use tokens for LLMs, most people are not informed about what it is and the process behind them. When an LLM learns or generates information, it undergoes a process called tokenization.

To understand how LLMs work, it is important to learn about tokenization and tokens. Here is a brief of how that works.
LLMs do not simply process text in a conventional manner as they convert any information given into smaller units called tokens. This process of turning text to conversation is called tokenization.
To enable this process, each LLM makes use of a tokenizer like OpenAI uses tiktoken for their GPT models. Using tokenization, LLMs can convert text into tokens to understand information and generate appropriate responses in any language.
Tokens are smaller units of text that are created through tokenization for LLMs to process. However, there is no fixed definition of what tokens are as each tokenizer handles the breakdown of text differently.
There are some general rules of defining tokens in English and here they are:
With these guidelines, you can estimate how tokens work but it is always better to use a calculator like the one above to calculate the number of tokens for popular LLMs.
As mentioned earlier, each tokenizer generates a different number of tokens from a text. For example, OpenAI’s tiktoken defines tokens differently than SentencePiece does for LLaMa/Gemini.
It is also important to note that each model has its respective token limit. That said, here are the popular LLMs and the respective tokenizers they use to break down sentences or paragraphs into tokens.
LLMs | Tokenizer | Token Limit |
---|---|---|
OpenAI GPT 4.0 and above | tiktoken | 128,000 tokens |
Anthropic Claude Sonnet 4 or Opus 4 | Custom Byte Pair Encoding (BPE) tokenizer | 200,000 tokens |
LLaMa 3 | SentencePiece | 128,000 tokens |
DeepSeek V3 | Custom Byte Pair Encoding (BPE) tokenizer | 32,000 tokens |
As the number of tokens differs from one model to other, that also affects the cost to use each LLM for input or output text.
As mentioned a little earlier, each model calculates tokens differently, and the cost of tokens can largely vary due to that. Thus, to learn about the different costs of using tokens on different LLMs, you can go to the pricing pages of the respective models as show below. :
LLMs | Pricing Page |
---|---|
OpenAI GPT | Openai price |
Anthropic Claude | Anthropic price |
DeepSeek API | Deepseek price |
As for Meta’s LLaMA, it is completely open-source, thus the pricing of the model depends based on different providers. This applies to DeepSeek V3 as well if any such provider is using the open-source version and not the API as listed above.

As the world moves toward AI automation and generation, learning about tokens becomes extremely important to utilize LLMs efficiently. Businesses will utilize LLMs through chatbots, where a knowledge base can be trained and utilized for enhanced responses.
This applies to REVE Chat as we utilize Brain AI to train knowledge bases, augment chatbots, and provide customers with personalized replies and unique experiences. This makes learning about LLMs very important to optimize chatbots in terms of operational costs, efficient workflows, and more. Here are the main reasons why tokens are important for businesses.
Thus, learning more about LLMs helps you with implementing the right one for your business and achieving reduced costs and higher efficiency.
Different models use different tokenizers, and they break text into tokens in unique ways. For examples, OpenAI uses tiktoken while LLaMa uses SentencePiece and each breaks down tokens differently
Short sentences can have punctuations, emojis, technical terms, or large words, which result in higher token counts depending on the LLM used.
Yes, in most LLM APIs, the total token usage includes both input (your prompt) and output (the model's response). Hence, a calculator like ours can really help you estimate and budget tokens for your chatbot.
Depending on the provider, a model may truncate the input, ignore excess tokens, or return an error. Thus, it is important to ensure that input and output stays within the token limit in total.
No, token counts vary by language. English is more compact, while other languages such as Chinese or Arabic, may require fewer or more tokens depending on the tokenizer.
These are often treated as individual tokens for most models. For example, a single emoji or bullet point can add to the total token count, even if the sentence is short.
Exceeding the limit cuts off context, reducing the quality of replies. Therefore, token efficient prompts keep chatbot conversations accurate and complete for customers.
