UnverifiedIn Claude Code, each model has its own prompt cache; switching models mid-session discards the cache, and the first request after switching re-reads the entire conversation with zero cache hits.72% similarUnverifiedWhen a large model outputs long code, it tends to omit parts midway, causing the code to be truncated and the web page to fail to open; the solution is to add a line to the prompt: "Output in two parts, do not omit anything."71% similarUnverifiedClaude Code optimizes through prompt caching, storing recent conversations in a high-speed cache to reduce the cost of repeated reads, but this only affects the unit price and does not reduce the total number of tokens that need to be processed71% similarUnverifiedSummarizationMiddleware's basic logic is that when the number of messages or the token count exceeds a threshold, it calls a summarization model to compress earlier conversation into a summary, freeing up context window space.70% similarUnverifiedCLIP文本编码器的标准上下文窗口长度约为77个Token，超出部分的语义信息会被截断或降权处理70% similar
