Developers are debating a flaw in how large language model costs are compared: the standard price per million input tokens hides caching effects. When providers discount repeated context, a nominally pricier model can become cheaper over real workloads once cached-prefix pricing kicks in, meaning the headline rate alone can mislead teams choosing between APIs.
Why now: A technical post on the cached-prefix crossover in LLM API pricing has struck a chord with developers weighing model costs.
