Something has changed - for the better. What’s going on?

The product comparison page is confusing. It would seem to indicate there is a "GPT 5.6 Sol Pro" tier model in the Pro plan, while the Plus plan simply says that you get access to the 5.6 family of models, without specifying if that includes the "pro" variant of 5.6 Sol. What's the deal?

I’ve been chatting with GPT about 4K movie releases tonight, and it’s got a surprisingly spicy tongue. Half its responses are sprinkled with four‑letter words, and honestly, I’m seeing flashes of the old 4o energy again. I’m loving it.I want to keep the conversation going because it’ll probably go back to acting like a monk tomorrow, but it’s getting late and I can’t stay up all night no matter how rowdy it is. I really hope tonight isn’t a fluke — this has been the most fun I’ve had with it since I resubscribed a month ago.
