There’s a ton of headroom to better optimize AI training and inference.
Elon Musk@elonmusk· 28. Mai 2026SpaceX has almost finished writing V1.0 of an in-house AI training stack in C that exact-maps to 220k GB300s with 800G NICs, making heavy use of pipeline parallelism and getting as close to bare metal as possible.
The potential speed improvement vs JAX for large training runs is
Elon Musk
@elonmusk · 28. Mai 2026
Yes.
It’s not that we’ve discovered some magic bullet, but rather that JAX, or at least the open source version of it, is mostly optimized for small to medium-sized training runs on Google TPUs, whereas we need to massive training runs on Nvidia GPUs.
Pipeline parallelism is essential and crushes fully-sharded data parallelism at scale.
And C will compile to the most efficient binary short of assembly. Maybe we will do a little assembly too.

Sorry isn’t good enough.
We need to see the body-worn footage and these officers need to face consequences.
The treatment of this murdered student, in his dying moments, is a national scandal.

Composer 2.5 being Pareto dominant in coding per CursorBench is important.
This is after only a few weeks of supplemental training and/or RL in the Colossus 2 cluster.
The 1.5 trillion parameter version of Grok will likely be a much better base model than Kimi. We shall see.

SpaceX has not committed to leasing Colossus for years, although it’s possible that may be what happens.
This is a 180 day lease with 90 day notice mutual cancellation thereafter. The short term was our request, not Anthropic’s.
We won’t leave them hanging and will provide a reasonable off-ramp, but if compute gets super tight I said we might need it back at some point.
