I get that Fable 5.1 is much more of a doer than previous models, but I’m not talking about that. I mean the sheer speed at which I get back a response do a scope/mechanism redesign question that Fable 5 would have had to deliberate on for 10+ seconds. Is this a tok/s difference on anthropic’s part, trying to make the model seem like a larger improvement? Or is 5.1 more token-efficient? Something else? I’ve also noticed in some cases there are summarized blocks where something has apparently gone in and summarized what the model’s doing instead of just letting me read its output. I swapped to verbose output in setting to stop that (because it’s terrible), but I’m wondering if that’s part of the same harness optimization push (if that IS what’s happening). submitted by /u/HelloMyNameIsAmanda
