Verified注意力机制的计算复杂度随上下文窗口长度呈平方级增长，导致推理延迟与成本急剧上升77% similarUnverified在推理阶段内存带宽往往比纯算力更早成为瓶颈，注意力机制需在每步生成时读取全部KV缓存，上下文长度增大时内存读写开销呈平方级增长77% similarUnverifiedReasoning Effort档位越高，模型可消耗的思考Token上限越大，但延迟和Token成本相应线性乃至超线性增长77% similarUnverified多模态能力的引入会显著增加推理延迟、显存占用和标注成本，完整的多模态生产系统远比单纯文本系统复杂77% similarUnverified更长的上下文不仅意味着更高的API费用，还会导致推理延迟增加和注意力稀释76% similar
