No, it is labeled as GPT-4, but last time I checked it was using GPT-3.5 under the hood. I asked about something recent that GPT-4 should know, can't remember what exactly, maybe about stable diffusion, and asked not to use the web search and it answered like GPT-3.5
Do you have a concrete example?
I just asked "can you answer questions without making a web search?" and it replied that it "includes knowledge up to 2021".
Yep, I use this very frequently (I use edge browser fwiw). Now I can be disappointed by gpt for free!
