UnverifiedThe Prefill stage is the first step of large language model inference, in which the model performs a complete forward computation in parallel over all input tokens to generate the KV Cache for every layer.75% similarUnverifiedThe prefill stage is compute-bound, requiring all input tokens to be processed at once to generate the KV Cache, with attention matrix computation complexity of O(n²).70% similarUnverified确定性工作流是一系列预先定义、按固定逻辑执行的步骤，输入相同则输出相同70% similarUnverifiedThe Prefill stage of LLM inference is a compute-intensive operation whose primary bottleneck is GPU/NPU compute (FLOPS).67% similarUnverifiedThe prefill stage of LLM inference processes all input tokens in parallel and generates the initial KV Cache; it is a compute-intensive operation and the direct determinant of TTFT.67% similar
