Saw the thread on the front page, thought it is a bit weird, so I tried myself, and while I don't know if it is google search or not, the model as it's served on z.ai is perfectly capable of real web search.
here is the sharelink for the chat in the screenshot: https://chat.z.ai/s/e21cbbf7-2e1b-49bf-adc4-260965383d61
anyway, with how easy it is to make AI say anything you want, or just use html edit to make a screenshot of anything, I think people here should be more skeptical of an out-of-context screenshot without a chat sharelink.
