What is a Token?
A token is the basic unit used by AI models to process text. A token can be a character, part of a word, or a complete word. Tokenization varies across different languages.
- English: approximately 4 characters = 1 token
- Chinese: approximately 1.5 characters = 1 token
- Punctuation marks are usually separate tokens
Cost Optimization Strategies
- Choose models appropriate for task complexity
- Streamline prompts, remove redundant information
- Use system prompts instead of repetitive user prompts
- Implement intelligent caching strategies
- Monitor API usage, set up cost alerts
Important Note
The token estimates provided by this calculator are for reference only. Actual token counts may vary slightly depending on the specific tokenization method of the model. Small-scale testing is recommended before formal use.
