Rumors are increasingly circulating that Opus is already being routed to Opus 5.2. It's also said to be a significant leap forward from Opus 5, but not quite reaching the level of Fable 5.
I'm hopeful that Anthropic is taking the criticism seriously and that with the next model we'll finally get a hardworking one that's less verbose, more efficient, and not so lazy. A release should be coming soon.
