The priority of the three layers of protection is: anything that can be solved by retrying within the same model should not switch models, and only when retries are exhausted does it enter the fallback stage.

UnverifiedThe coarse-filtering stage should ensure sufficient recall margin — it is better to over-recall and let the model eliminate candidates than to miss the correct option by saving tokens, because recall failures at the retrieval layer cannot be recovered by subsequent models.77% similarUnverifiedA fallback chain should be kept short — three models is generally the upper limit — as the worst-case path latency worsens beyond that.70% similarUnverified引入重试机制时应带指数退避，但需警惕重试放大效应70% similarUnverifiedRetry strategies should set a maximum number of retries and a total timeout budget, and handle retries idempotently to avoid duplicate side effects when non-idempotent requests are retried.69% similarUnverified采用多模型策略可以对冲单一模型延期或性能波动带来的风险68% similar
