Why are we not just in a free lunch moment but with harnesses, rather than models?
Right now a lot of people have a lot of opinions on which model to use for which task. They get better results for less money by judiciously switching between Fable and Opus and whatever else. Spending my time learning this skill would have an immediate benefit for me.
But on the other hand, maybe the harness vendors will just solve it in 6 months? I'll ask a question, something in Claude Code (or whatever we're using by then) will figure out the most effective model based on the question and the context and my apparent willingness to get it right. I'll get billed X or 10x as appropriate, and I'll be happy with that, because that's what I would have paid if I made my own choice of model every time.
Claude Code already does this a bit, sometimes it will tell me it picked Sonnet for such and such a sub agent, or some other detail I'd rather not care about. The best humans seem to be better at deciding what model to use than any of the tools is, but surely that won't last long.
