What is Token Counting?

Tokens are the basic units of text that AI models process. They're not exactly words or characters - one token typically equals 3-4 characters or roughly 0.75 words. Understanding token usage is crucial for budgeting AI API costs and optimizing prompts.

How Token Counting Works

Our calculator estimates token usage using these approximations:

1 token ≈ 4 characters - A rough but reliable estimate
1 token ≈ 0.75 words - Word-based approximation
Tokens include punctuation - Spaces and special characters count
Output ratio matters - AI responses consume tokens too

Tips for Cost Optimization

Shorten prompts - Remove unnecessary context for low-cost operations
Use cheaper models - GPT-3.5/Claude Haiku for simple tasks
Batch requests - Process multiple items in one API call
Cache responses - Reuse similar outputs to save tokens
Monitor usage - Track token consumption to identify costly operations
Set limits - Use max_tokens parameter to control output length

Understanding API Pricing

AI model pricing typically charges per million tokens for both input and output:

Input tokens - What you send to the AI (your prompt)
Output tokens - What the AI generates (its response)
Output is usually 2-5x more expensive - Generating content costs more than reading it
All models offer different pricing - Compare before committing to one
