Context reranking means using a cheap small model to score and rank candidate code snippets, files, or historical comments, sending only the most relevant small amount of content into the frontier model's cache to reduce input token costs.

UnverifiedContext compression reduces the number of tokens passed to the model per request through summarization, retrieval, or discarding redundant history, thereby directly lowering compute costs; caching, by contrast, stores the responses to common questions or high-frequency conversations to avoid repeated inference.80% similarUnverifiedSemantic Cache can reduce third-party large model API call costs by reusing historical answers for similar questions.70% similarVerifiedReranking technology first uses coarse retrieval to recall a large number of candidate segments, then uses a fine-ranking model to re-score them, keeping only the most relevant content to feed into the model.68% similarUnverifiedProgressive disclosure, through the three-level hierarchy of "metadata → detailed guidance →附属 resources," lets the model first make routing decisions using low-cost information and then expand high-cost content on demand, thereby avoiding the context window being occupied by irrelevant content.66% similarUnverifiedAs interactions accumulate, raw historical records will exceed the model's context window limit, requiring periodic summarization or tiered storage for memory compression.65% similar
