New in-depth blog post time: "Inside NVIDIA GPUs: Anatomy of high performance matmul kernels". If you want to deeply understand how one writes state of the art matmul kernels in CUDA read along. (Remember matmul is the single most important operation that transformers execute…
we are opening 3 new roles at xAI to shape the future of software engineering. Join us in product, infrastructure, or post-training for the grok-code-team and help push the frontier forward with the best team in the world 🚀
I’m not arguing for immortality. I’m observing that our tolerance and embrace of death is the greatest existential risk we face as a species. For it then rationalizes our other self destructive tendencies, framing them as virtues.
This is funny because gpu compilers suck. No one says this about the cpu compilers

This false nomenclature of “researcher” and “engineer”, which is a thinly-masked way of describing a two-tier engineering system, is being deleted from @xai today. There are only engineers. Researcher is a relic term from academia.

It has been really exciting to cook grok3-mini, an amazing experience of collaboration across teams in xAI! Here are some fun facts: 1) The pretraining was a one-shot run, no rewind back, no loss spike, and it's a cost-efficient train. We have a very stable training recipe and…
