LLM Gateway / Model Router

Also written as AI Gateway, LLM Gateway, LiteLLM, OpenRouter, Model Routing

A layer between an application and the AI model providers that handles switching between models, fallbacks when a provider is down, rate limits, cost tracking and logging. A router can also send easy requests to a cheap model and hard ones to a stronger one.

Think of it like

A company travel desk that books whichever airline suits each trip and rebooks you when a flight is cancelled.

Junior or senior?

Shows platform thinking about AI beyond one feature.

Senior sounds like

Can talk about cost savings, handling a provider outage, or how routing decisions were checked for quality.

Ask them

“Why did you put a gateway in front of the models, and what did it save you or protect you from?”
