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.

I use C/C++ for all my projects. Debt Badge, Clucks Capacitor, homemade power-wall, sculpting software for my haptic interface. I suppose with AI assisting, the clunkiness of developing in C disappears and the efficiency shines. How soon until the language doesn’t matter?

"How soon until the language doesn’t matter?" Have been toying with this idea the past few days actually! Typically AI writes code in a python/ts/c and then a compiler translates for the CPU. Would going directly from lanuage to CPU make sense?🧵

Elon, Jack, and a US Senator in the same Twitter thread - talking C. The online world is flat.

I’m resurrecting this old C codebase for VPN servers: github.com/derekm/racoon2 It’s hard work getting low-drift production-quality code from these models.
