What happens to your app when your LLM provider goes down

Short summary

An AI infrastructure engineer argues that every LLM-powered app should treat its provider as an unreliable dependency and route across multiple providers. The hard part is the middleware layer that normalizes different provider APIs, response shapes, and failure modes into a single interface. The author promises future posts covering the unglamorous engineering details of building reliable AI infrastructure.

• •Single-provider LLM apps break when the provider has an outage or rate-limits you
• •Multi-provider routing requires a middleware layer to normalize different APIs and failure modes
• •Author plans a series on practical AI infrastructure reliability engineering
