The premise
Tokenizer behavior creates cost and quality variation across content types; awareness drives better choices.
What AI does well here
- Measure token usage per content type (English, multilingual, code, structured data)
- Choose models with tokenizers efficient for your content
- Optimize prompts for token efficiency where it matters
- Account for non-English content cost in budgets
What AI cannot do
- Eliminate tokenizer differences
- Predict token cost without measurement
- Make all content equally token-efficient
