Hello i am having a lot of memory problems while trying to open long chats in the new ui. In the old, it was working. I noticed that the older ui was working, but some of the new models are not in this ui. I mean new models like claude 4, grok 4, and few others. Can them be added to this old ui please ? thanks in advance
