Unverified50% confidenceFactExact time
The encoder uses bidirectional attention, so every time the question changes, the attention weights at all positions change as a whole, and even placing the context first cannot enable cache reuse; the more questions and the longer the context, the heavier the repeated computation.

UnverifiedThe model uses a bidirectional attention encoder architecture, completing inference in a single forward pass, with constant-level latency that does not grow linearly with content length.75% similarUnverified在推理阶段输入内容通过并行化注意力机制一次性处理，而输出内容需自回归逐Token生成，无法并行化，构成大模型推理延迟的根本瓶颈74% similarVerifiedEven models with a million-token context face an attention dilution problem when handling large codebases—when the context is too long, the model's attention to early content drops significantly.72% similarUnverifiedCode review is attention-intensive work with extremely high cognitive load; when AI multiplies the number of PRs several-fold, reviewers' attention becomes a scarce resource, shallow review becomes the default behavior, and this is the main channel for defect escape.71% 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71% similar
