When I was building Logicvisor — an AI-powered tool that reviews your algorithmic code, breaks down time and space complexity, and gives you the kind of feedback you'd want before a technical interview — I had to make a foundational architectural decision early on.

Where do the AI calls actually live?

It sounds simple. It really isn't. And I think it's a decision a lot of developers make too quickly, usually defaulting to whatever gets something running fastest. So I want to walk through how I thought about it, what the tradeoffs actually look like in practice, and why for Logicvisor — and honestly most production projects I work on — the answer was never really up for debate.
