Sonnet 5 makes more sense when you pretend the higher thinking efforts don't exist. (His test was on xhigh)Anthropic's own release announcement mentioned that it's less cost competitive per task than Opus at higher thinking levels. It's significantly cheaper at lower levels though.
I'm wondering if this is going to be a universal pattern of smaller models: they're less smart, so to achieve the same benchmark results they have to think a lot more and hence become expensive.
Benchmarks force models to solve the problem entirely by themselves, requiring thinking. But if you pair them with a smart model (who thinks and solves beforehand) they won't need to solve the hard parts and can run on low/med. I suspect that was Anthropic's intention.
