General-purpose models are best when the job is a little different every time, so research, drafting, analysis and cleaning up a messy spreadsheet all sit naturally in a chat window.
A no-code workflow builder like Gumloop, n8n or Make is better when you need a real trigger, or when the exact same thing has to happen the exact same way every time, because a model might take a different route to the answer on Tuesday than it took on Monday. Albato has a gut check I use on myself: if you can draw the whole process as a flowchart with every branch labelled ahead of time, you want workflow automation and not an agent.1
Most real builds use both. On a call in June a founder was stuck generating training data by hand, and what I suggested was a spreadsheet with the source data and a prompt as the first two columns, run through the same Gumloop workflow once per row. You can plug your own model tokens into it, and it does not need an engineer to keep running.
