VerifiedCombining strategies such as RAG, prompt caching, context compression, and model fine-tuning can often reduce costs by an order of magnitude without sacrificing quality.76% similarUnverifiedRAG依赖精确的向量检索推理成本低但受限于检索质量，超长上下文窗口避免检索失配但KV缓存显存占用随上下文长度线性增长导致推理延迟和成本上升74% similarUnverified更长的上下文窗口并未消除注意力稀释效应，反而带来更高的单次调用成本73% similarUnverifiedHigh throughput is achieved through batching, which increases the total number of tokens processed per unit of time but raises time-to-first-byte latency; low latency requires small batches or no batching, which reduces hardware utilization and raises the cost per token.70% similarUnverifiedToken optimization approaches such as context compression, RAG, sliding window strategies, and KV Cache optimization all involve trade-offs between information loss and reasoning quality.69% similar
