English(EN) What an LLM API call really costs: the formula and four levers that move the bill

LLM API成本:公式、影响因素与模型对比

使用大型语言模型API的成本由一个考虑输入和输出token的公式决定,其中输出token的成本通常远高于输入token。最终账单会受到多种因素的影响,包括使用的模型层级、缓存机制的效率、批量处理请求的能力以及对超长提示的处理方式。根据实际性能和特定工作负载下的成本来比较不同模型,比直接比较品牌更有效。 AI

影响 为开发者和企业提供了优化LLM API支出的实用指导。
