Architecture

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. ...

Connecting both Claude and OpenAI in production is the easy part. The hard part is keeping the system stable across the quality-latency-cost triangle. Without a routing gateway, you usually get latency spikes, runaway bills, and ugly cascading failures. ...
