Just because it would be nice to have that, doesn’t mean that it’s a good idea in practice, or that there currently exists a viable way to implement it.
> At any price point, there exists the best model/effort combination.
People are already offended by any barely perceptible tweaks to models; can’t wait to hear what they think about having their options reduced to whatever Anthropic decides is the pareto-optimal “do the thinky thing” setting this week.
Yet, current non-users simply don't care about reading 4 system cards during roll-in and then keeping up with new ones every few weeks.
And, a solid adaptive thinking classifier is trivial compared to Anthropic's remaining tech stack. Task complexity estimation and model/effort selection are simple predictions with clear proxies in current data and millions of training samples generated daily by current users.
