People on X: “CLAUDE IS BACK, baby!” Listen, Opus 5.5 is incredible and probably my favorite overall model right now, but it is still ridiculously verbose and over-justifies and over-qualifies everything. I curse at it less than previous models, but it still responds in a way that - dare I say - makes no sense to the average reader? It always feels so difficult to skim. And that makes it worse in a business or personal setting. See comparison examples from Claude chat on mobile with Opus 5.5 medium, ChatGPT Work on mobile with GPT-6 Sol medium, and Instinct.
