Saraswati Stitch®contact@saraswatistitch.comOrchestration is the layer that coordinates several models, tools, and steps into one working pipeline, deciding what runs when and passing results from one stage to the next.
Real systems are rarely one model call. They are a sequence: classify the request, retrieve the right data, draft a response, check it, act. Orchestration is the conductor that runs those steps in order, handles failures, and keeps state.
It is where most of the engineering actually lives once the model choice is made, and it is what makes the difference between a clever prompt and a dependable service.
