I’ve seen overwhelmingly that when a model is good people see it, and when it isn’t, they criticize. I’ve seen nothing but ‘wow this is a huge step up’ from Opus 5.5. I felt this way about Opus 4.5, GPT-5.6 Sol/Luna, and to a lesser extent with Fable and Astra. But Opus 5 was ass, and the entire gpt 6 line feels like OpenAI’s version of that.
