This article explains the unit economics of LLM automation, focusing on how to track and report costs accurately. It breaks down LLM API expenses into four key variables: input tokens, output tokens, cache hits, and token price, emphasizing that model selection can lead to cost differences of 10-30x. The author provides examples using hypothetical GPT-5 and GPT-5-mini scenarios to illustrate how caching and model choice significantly impact monthly expenses, potentially reducing costs by up to 13x.
