The MFU on this full C++ stack is part of the reason xAI is churning out so many models. I would bet their stack is full of inline PTX and most likely completely AI generated by stronger models like GPT and Claude Fable.
The need for higher level frameworks for prod training is

Our C/C++ training stack was written by humans. AI is not yet good enough for extremely high performance software (but it will be).

Leslie Stahl alleges hiring pardon lobbyists in Trump adminstration is "a new system".
Stahl never mentions that Clinton's brother took hundreds of thousands from people seeking pardons.
Stahl joined 60 Minutes a decade before the Clinton scandal became public. @bariweiss

Hello @elonmusk 👋
A bit nervous to ask this publicly, but—
we’re hosting a small experimental closed event for KEMURI at our UNSEEN studio in Tokyo during TGS.
If you’re around, I’d love to invite you.
I also have something I’d like to talk with you about regarding UNSEEN.
Can

My @bot Grok Bot team just sold their first item on @Poshmarkapp, amazing.
- Poshy built the ad, advised on pricing, followed up on offers.
- Cosie monitored her.
- Weary is now updating my online wardrobe to archive the shoes that sold.
Well done, team

Named my grok bot after the sentient AI, Jane, in speaker for the dead.
I look forward to when I can sub-vocalize like Ender to communicate with Jane, but would honestly even be happy with verbal communication back and forth like we have for the Grok app.
Right now it seems I can dictate, but the app needs to start and stop recording, then process and reply which it does in text only. it's clunky. Let's take the excellent conversation flow capability from Grok and bring it to Grok bot

Grok Build just got another update focused on making multi-agent sessions easier to read and navigate
Subagent groups now clearly show how many agents are still running versus finished, dashboard search and resume selection behave more predictably, cancellation banners show the actual cause, and long paths are cleaned up across headers and dashboards
MCP handling also gets a useful fix....tools with long server prefixes are no longer silently dropped
Another small release that makes busy agent sessions much easier to understand at a glance
Release Notes: v1.0.31
Bug Fixes: • Folded subagent groups in scrollback now correctly label how many are still running versus completed.
• Dashboard search and the resume picker now clearly indicate the active text field and restore list selection after search.
• Dock sections no longer keep a selection highlight after you collapse them with a click.
• Worktree paths no longer show an extra suffix in the header or dashboard.
• MCP tools with long server prefixes are now kept instead of being silently dropped.
• Turn cancelled banners now correctly name the cause instead of always saying "by user".
• Long paths in headers are now always shortened to the last two components
X Freeze@XFreeze· 12 sept. 2026Grok Build just got another clean usability + performance upgrade
The session header is now cleaner, long-running sessions are easier to track with proper hour-based timers, Watchers and Loops show exactly when they’ll run next, and workflow status is directly clickable from the

Eight years ago, Elon Musk said:
“Mark my words: AI is far more dangerous than nukes.”
Elon didn’t give in to the AI doomers. In fact, his position is very different from theirs. He has warned about the risks of AI for years while still pushing for its development, with a strong focus on safety. His view is that companies should build powerful AI, but do it safely and responsibly, even if that means slowing the pace when necessary
“I think the danger of AI is much greater than the danger of nuclear warheads by a lot and nobody would suggest that we allow anyone to just build Nuclear warheads if they want that? That would be insane. And Far.”
