From Notebook to Production

Deploy

Part of: Deploying & Monitoring LLM Apps

The demo worked on the first try in a notebook. Two weeks later the same code is paging an engineer at 2 a.m. because a hardcoded API key leaked, a 30-second model call hung the web server, and one user's prompt crashed the whole process. Nothing about the model changed. Everything about the environment did. What it is Deployment is the work of turning a one-off script into a service that strangers can hit, all day, without you watching. A notebook runs once, for you, with your secrets typed inline and failures you can see. Production runs continuously, for everyone, with secrets hidden, failures logged, and load you don't control. The model call is the easy 10 percent. The other 90 percent is the wrapper around it: a request comes in, you validate it, call the model, handle the things that go wrong, and return a clean response. How it works A minimal production wrapper has a shape that almost never changes: The four moves are always the same: read config from the environment , validate the input, call the model inside a try/except, and return a structured response instead of crashing. The notebook version skips every one of these because it only ever runs in your hands. Why it mat
