I think it's funny how at almost all of these launch events, Musk always goes off about how the current product is still trash compared to what he wants next. Everyone always gets silent on stage waiting to go back to hyping the current thing.

Sounds like Grok 4 has o3 stuff where it spins off a whole bunch of instances. So if grok 3 would get the right answer 1% of the time just due to random chance, grok 4 would get it right by answering a 100 times and selecting the best.

Oh I guess this benchmark for Humanity's Last Exam is really impressive. They didn't show how well other companies did, so I had no clue.

[Legend]

I want to see how well it does on the video game benchmark. That's the most interesting one.

Good voice. Whispering is impressive.
