You don't even need to start off with Fable. Give Opus 5.5 a try first and then then try Fable if you feel like you need to push it further

I have a longer history of agents sessions and used those to benchmark the different models. Sonnet 5.5 is already pretty strong, but not always as careful (leaked secrets into the session). Opus 5.5 is already able to solve everything I'm doing. You might not need Fable for anything. Biggest different between Opus and Fable in my benchmarks was price. Also Opus 5.5 is cheaper now then previous Opus so you might also not need Sonnet as much for cost savings.

Based on blended benchmarks from Artificial Analysis, Opus 5.5 is stronger than Fable 5.1. Are you finding use cases where Fable is superior?

Fable can go deeper than Opus in my experience. Opus is incredible for relatively now-simple things like coding, but Fable has delivered improved results for me in data analysis on relatively obscure topics. That said one gets much more Opus for a subscription than one does Fable, so obviously benchmark your own cases and come up with your own cost benefit analysis.
