We have dumped JAX/SGLang and rewritten the entire RL and inference stack from scratch in C/C++, which took some extra time.
Training (aka pre-training) is done. Lot of cleanup was needed on the SFT data to get that mostly right. Now, 4.8 is in RL and the evals are starting to climb. We will do a soft rollout to Bot users later this week and see how it goes.
Grok 4.8 will bear no resemblance to 4.7 (thankfully). It is not yet incredible, but, this time, the foundations are built right, so I expect it to evolve to be something special.
It is kind of remarkable that a national government can just lie so brazenly about the motivations of a mass killer and the media will quite happily parrot those lies. Whatever's wrong with X now, it's still somewhere you can and should go to learn the truth.

Arabs won't be a minority in Arabia
Jews won't be a minority in Israel
Indians won't be a minority in India
Chinese won't be a minority in China
Only White Europeans are projected to be the minority in all their countries
Objecting to this is "White supremacy"
It’s a metaphor I keep coming back to; a nation can have a decisive lead and then simply throw it away for bad, short-term reasons.
And the damning thing is, you’ll probably not realise how bad a decision it was in your own lifetime. You’ll think you won.
