Unverifiedllama.cpp通过mmap机制将部分权重映射到内存/磁盘，但调度策略对模型结构不知情，无法做出智能预取决策80% similarUnverifiedllama.cpp项目让量化模型在各种硬件上本地推理成为可能，MLC-LLM专注于移动端编译优化66% similarUnverified本地模型的可用内存和显存（VRAM）直接决定可获得的上下文窗口长度，因为推理需在显存中维护 KV Cache65% similarUnverifiedLLM自回归解码阶段每生成一个token都需从显存加载全量模型权重，批量较小时形成内存墙65% similarUnverifiedLLM的记忆依赖于上下文窗口，即模型在单次推理时能够处理的最大Token数量65% similar
