UnverifiedSwitching models causes context cache invalidation, requiring the re-injection of state such as codebase structure, task objectives, and completed steps via prompts, consuming additional tokens and potentially introducing errors.78% similarUnverifiedSwitching models mid-session or enabling Fast Mode will break the cache and cause a full recalculation of history, because each model maintains an independent cache space.72% similarUnverified更换或升级嵌入模型时，旧向量与新向量处于不同语义空间无法直接比较，往往需要全量重建索引72% similarUnverifiedDuring LangGraph failovers, call receipt information (the model catalog ID of the actually serving model, whether it was a rejection or empty result, and call cost) may be lost, causing downstream nodes to make incorrect judgments.71% similarUnverifiedPrompt cache misses become a fatal problem, because the compression toolchain rewriting history changes the prefix, invalidating all caches and causing the entire context to be repaid at full price in each subsequent round.70% similar
