随着上下文窗口的不断扩大，大型语言模型（LLM）面临着显著的性能瓶颈。尽管键值（KV）缓存对于避免重复计算至关重要，但长上下文缓存的存储开销会迅速超出GPU内存容量，迫使生产系统在多级内存结构中采用分层缓存策略。然而，将大量缓存的上下文重新 ...

Tokens are the fundamental units that LLMs process. Instead of working with raw text (characters or whole words), LLMs convert input text into a sequence of numeric IDs called tokens using a ...
