What is an LLM Gateway? A Deep Dive into the Backbone of Scalable AI Applications

Описание: As AI applications scale in 2025, the need for fast, consistent, and reliable communication with large language models (LLMs) has made the LLM Gateway a critical part of modern AI infrastructure.

In this video, we explain what an LLM gateway is, how it works, and why it’s essential for teams deploying AI systems at scale. An LLM gateway acts as a middleware layer between your application and multiple LLM providers — handling routing, load balancing, caching, provider fallback, and performance optimization automatically.

You’ll learn:

The core architecture of an LLM gateway — from request handling and token normalization to multi-provider abstraction.

How it improves latency, scalability, and fault tolerance in production AI systems.

Why teams use gateways to unify OpenAI, Anthropic, Google, and local LLMs under one consistent API.

The trade-offs between self-hosted gateways and managed ones.

Examples of emerging open-source LLM gateways and performance considerations when choosing one. For example Bifrost : https://www.getmaxim.ai/bifrost
