Grok 4.5 is only 1.5T parameters.
Kimi K3 is 2.8T... and costs 3× more per task.
SpaceXAI cracked intelligence efficiency.
Now imagine Grok at 3T.

Our 2T model, which is better than our 1.5T in every way, will finish initial training next week. It might be able to exceed Kimi, but with speed and token efficiency close to our 1.5T (aka Grok 4.5).
