LLM 下一个词预测详解:Transformer 层、注意力机制和 KV 缓存

大型语言模型通过预测序列中的下一个词来工作,这个过程包括对输入文本进行分词,并将其通过 Transformer 层。这些层利用注意力机制,根据查询(query)、键(key)和值(value)向量来权衡不同词元(token)的重要性,从而使模型能够理解上下文。在推理过程中,'预填充'(prefill)阶段并行处理整个提示(prompt),并将中间计算结果存储在 KV 缓存中,这对于后续词元的有效 '解码'(decode)生成至关重要。然而,这个 KV 缓存会消耗大量内存,尤其是在处理长上下文时,这推动了优化技术的发展。 AI

影响 解释了 LLM 的核心推理机制,强调了上下文长度与计算成本之间的权衡。
