Symfony AI gives you the components to ship AI features. It doesn't tell you how to structure them once they hit production. Human-in-the-loop approval, workflows that run for minutes instead of milliseconds, retries, cost tracking, and the extension points you reach for when the happy path stops being enough. This talk walks through the patterns that hold up in real applications, the ones that don't, and where the component boundaries actually sit. You'll leave with a working mental model for designing AI features, not just calling a model.
