Right, so. This is a post I wish existed six months ago when we were first wiring LLMs into our Go backend at Huma. Most of the tutorials out there for LLM integration assume you're in Python. Which is fine — a lot of ML infrastructure is Python, and libraries like LangChain, LiteLLM, and friends are well-documented. But if you're running a Go service stack and you want to add LLM calls without bolting on a whole Python sidecar, the path is less obvious. Here's what we actually learned, includ
