Frequently Asked Questions (FAQ)
Tokens are pieces of text that AI models process. In English, a token is approximately 4 characters or 3/4 of a word. Models like GPT-4 have token limits that constrain the amount of text they can process at once.
This calculator provides an approximation based on character count. Actual token counts may vary depending on the specific tokenizer used by each model. For precise counts, you would need to use the model's specific tokenizer.
More powerful models like GPT-4 and Claude 3 require more computational resources and have more capabilities, which is reflected in their higher pricing compared to models like GPT-3.5 Turbo.
Input tokens are what you send to the AI model (your prompt or question), while output tokens are what the model generates in response. Most models charge different rates for input versus output tokens.
No. All token calculations are done locally in your browser. Your text is never sent to any server.
Understanding AI Token Usage
AI language models like GPT-4, Claude, and others process text as "tokens." Understanding token usage is important for:
- Cost management: API calls are typically priced per 1,000 tokens
- Context limitations: Models have maximum token limits (e.g., GPT-4 can handle up to 128K tokens)
- Performance optimization: Efficient prompting can reduce costs and improve responses
Token count varies by language. While English averages about 4 characters or 3/4 of a word per token, languages with non-Latin alphabets may use more tokens per word.
This calculator provides estimates to help you plan your AI usage and understand potential costs before making API calls.
