Tool calling models, ranked

An agent lives or dies on two things: calling the right function with valid arguments, and returning JSON your code can parse without a retry. Everything here does both. In a multi-step loop, a cheaper model with a low error rate beats an expensive one with the same error rate, because every retry pays twice.
