The Tokenizer Tax: Why AI Sticker Prices Are a Lie
153
The 'price per million tokens' metric is a misleading illusion because different model tokenizers can quietly inflate your bill by over 70% for the exact same code.
Token Optimization
Techniques and tools for reducing the number of tokens consumed by LLM interactions, lowering API costs and improving response speed without sacrificing output quality.
