Failover

If your production stack calls both Claude and OpenAI, the hard part is not API integration. The hard part is keeping user experience stable when one provider starts throwing 429/5xx spikes, regional latency, or timeout storms. This guide gives you a practical dual-provider gateway playbook: health probes, circuit breaking, SLA-aware fallback, and observability loops. The goal is not “never fail.” The goal is controlled failure with controlled cost and controlled latency. ...

当你的生产系统同时接入 Claude 和 OpenAI，真正难的不是“接上 API”，而是在故障发生时还能稳态服务。一个供应商偶发 429/5xx、区域波动或模型超时，都会把下游体验打穿。 这篇给你一套可直接落地的双供应商网关方案：健康探测、熔断切换、SLA 分级回退、以及可观测性闭环。目标不是追求“永不失败”，而是失败可控、成本可控、体验可控。 ...
