Token Calculator User Guide
What are Tokens?
Tokens are the basic units that AI models use to process text. A token can be a character, part of a word, or a complete word. Different languages have different tokenization methods.
- English: ~4 characters = 1 token
- Chinese: ~1.5 characters = 1 token
- Punctuation marks are usually separate tokens
Cost Optimization Strategies
- Choose models suitable for task complexity
- Streamline prompts, remove redundancy
- Use system prompts instead of repetitive user prompts
- Implement intelligent caching strategies
- Monitor API usage, set cost alerts
Important Note
The token estimates provided by this calculator are for reference only. Actual token counts may vary slightly due to the specific tokenization methods of different models. We recommend small-scale testing before formal use.
