Go try out GPT-5.6 Sol in Chat mode right now. I'm starting to think we might be looking at something genuinely impressive here. It suddenly feels a lot closer to the warmth and personality GPT-4o used to bring to conversations. If this is secretly a GPT-6 Sol test, I'm VERY pleased with what I'm seeing so far. The model comes across charismatic, sharp, funny, and it's also churning out surprisingly good visual illustrations for nearly everything.
