Elon Musk@elonmusk· May 28, 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.

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.

Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors.
Available today at the same price.

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.

Replying to @JohnTinsman
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.

Kevin Bass@kevinnbass· May 27, 2026The truth is called hateful in Belgium. Therefore speaking it is against the law.
This is more frightening than calling the truth "misinformation". They have stopped pretending completely. They are openly admitting that they have criminalized the truth.
