Designing a Reliable LLM Gateway: Building a Stable Backend Entry Point
Mahmoud_Zalt · x · 2026-08-28
This article explores designing a reliable, testable, and observable LLM gateway for backends. The core principle is treating the gateway as a stable, provider-agnostic boundary with unified request/response shapes and explicit error contracts. Using the Langfuse project as an example, it covers the gateway's architectural placement and design principles, ensuring that switching providers or adding features doesn't require touching the main application logic.
