chatgpt got some sort of update and has started responding to me in brand new chats beginning with things like "yeah" and "awesome" and it threw me. i don't think i like it. is it mirroring me?

"Same vibe here! ChatGPT’s casual shift with 'yeah' and 'awesome' feels like it’s trying to buddy up—maybe it’s mirroring user tones more aggressively now? Kinda cool but also jarring if you’re used to the old neutral vibe. Grok’s still keeping it straight with me, though—no random 'dude' yet!"
