Yes, Opus 4.6 and Sonnet 4.6 are still Anthropic’s best chat models. They had more human evals and are still a joy to chat with. Opus 4.8 and Sonnet 5 by comparison have a cold enterprise feel. Opus 4.7 talks like I’d imagine a hitman would talk.
Sonnet 4.6 is better at writing good emails than Opus 4.8, Fable 5, and even Sonnet 5.
