Go Dual-Provider LLM Routing (OpenAI + Claude): Timeout Tiers, Cost Caps, and Fallback Control

Wed, 08 Apr 2026 01:22:53 +0000

If your Go service relies on one LLM provider, two failures hurt the most, timeout spikes and billing spikes. A real production setup is not just “add another provider”, it is a single control plane for routing, timeout tiers, cost caps, and fallback.

This guide gives you a practical OpenAI + Claude dual-provider pattern with one priority, keep uptime first, then optimize quality.

Go 服务双栈模型路由（OpenAI/Claude）：超时分层、成本上限与降级回退

线上接入单一模型供应商，最怕两件事，突发超时和账单失控。真正可落地的方案不是“多接一个模型”这么简单，而是把路由、超时、成本、回退放进同一个控制面。

这篇给你一套 Go 可直接落地的双栈路由框架，目标是三件事，稳定性优先、成本可控、故障可快速止血。
