Unverified旗舰模型的单次推理成本可能是轻量模型的数十乃至上百倍，源于参数量、上下文窗口长度、推理步骤复杂度等因素78% similarUnverifiedTwo models with similar intelligence scores may differ in inference cost by several times or even an order of magnitude.78% similarUnverifiedThe price of output tokens for large language models is typically 4–8 times that of input tokens, because output involves autoregressive generation requiring multiple forward passes, resulting in higher marginal costs.77% similarUnverified对万亿参数模型而言，处理长上下文时KV Cache的显存开销甚至可能超过模型权重本身76% similarUnverified大模型API计费通常按输入和输出token分别计价，不同模型单价差异可达百倍76% similar
