Understanding Tokens
What is a Token?
A token is the basic unit of text that AI models process. One token is approximately 4 characters or 0.75 words in English. Different models may tokenize text differently.
Common Token Counts
- • "Hello" = 1 token
- • "Hello world" = 2 tokens
- • 1 paragraph ≈ 50-100 tokens
- • 1 page of text ≈ 300-400 tokens
Cost Estimation
Costs are calculated based on current model pricing. Input tokens (your prompt) and output tokens (the response) may have different rates.
Cost Factors
- Model tier (GPT-4 costs more than GPT-3.5)
- Input vs output token rates
- Prompt length and expected response length
Tips & Best Practices
Optimization Tips
- Remove unnecessary filler words and phrases
- Use concise instructions without losing clarity
- Consider shorter model responses when appropriate
- Test different prompt structures for efficiency
Watch Out For
- Long system prompts that repeat on every call
- Unnecessary examples in few-shot prompts
- Context window limits for your chosen model
