AI agents vs AI chatbots: what are companies actually using in production today?

It feels like everyone is talking about AI agents right now, but when I look at actual production systems, most companies still seem to rely heavily on chatbots or assistant-style tools. From what I’ve seen, chatbots still handle a lot of repetitive workflows, while agents are mostly used in controlled environments where they can execute specific tasks. The gap between what’s being marketed and what’s actually running in production still feels pretty big. Curious what others are seeing in real-world setups.
