Okay, I found it!
There’s a drop-down bar that lets you choose Grok, Grok 2 or Grok 3
Cool. Have you tried it out yet? As i said in another post, i find it absolutely hilarious when it’s trying to be. Geesh, AI is not only far faster than us but funnier too. Which is something Star Trek TNG got wrong (Data bombed as a stand-up comic, after all lol).
