This article debunks five common myths about the cost of using Large Language Models (LLMs), particularly concerning free tokens and requests. It explains that failed requests still consume tokens, that the 'envelope' of a request (including system prompts and conversation history) is often larger than the user's prompt itself, and that retries and caching strategies significantly impact overall costs. The author emphasizes the need to track actual task completion costs rather than just HTTP calls and provides a Python script to help users build their own spend ledger. AI
