Open WebUI is the front end most people slap in front of Ollama and call it a day — a tidy ChatGPT-alike that talks to local models. That’s fine until you want the model to do something: hit your internal docs, call an API, run a query, or chain a couple of models together. The built-in features cover some of this, but the real escape hatch is Pipelines: a separate plugin server that lets you insert arbitrary Python into the request flow. It’s the difference between “chat with a model” and “wire a model into your systems.”
