@bneyshabur @MirendilAI @a16z @kleinerperkins Ayooo congrats! Onwards to democratize AI R&D!
@kevinsxu You were the first person that convinced me to seriously look into Nebius. It's been a fun ride!
@edgefills Not to mention the risk of angering the Knicks mob - god forbid the people at the bar peek at the trade you put on. You may have come out with a Game 5 ticket but at what cost! x.com/Raindropsmedia…
Knicks fans stomp out a Spurs fan right in front of police. 😳
@aashaysanghvi_ we also invested in bloom, which has been quite a rollercoaster ride
goat when it comes to s-1 analysis
SpaceX filed its S-1 last week, and my partner @ausw2000 read all 318 pages (and made all the charts) so you don’t have to. The result: three businesses in one — Space, Connectivity (Starlink), and AI. AI is set to become the largest revenue segment within a year. The company
The synergy is pretty impressive imo. SpaceX paid down xAI debt from Colossus I and II, reducing interest rates by 800bps. AI revenue will pretty much be even with Connectivity revenue this year, boosting valuation further. What I'm curious about is how the rev is split between xAI and the SPV for the compute that Anthropic is renting. It'd give a good view into margins as well.
@taiuti @reactorworld Congrats dude! One of the coolest announcement vids I’ve seen!
@trengriffin The section about cereal vs. airlines makes me think of the intense competition among AI companies today. It'll be interesting to see where pricing power concentrates on the stack.
a neocloud should hit the bid on the single H100 just for the clout
Really happy to hear that Starcloud is using SpaceX for launch. Such a good name. And for all the orbital compute skeptics, they have an H100 in space today that has been used for both training and inference.
Another datapoint: Napoleon was tutored by Laplace. Napoleon considered himself to be a “scientist in uniform” and would study physics, engineering, metallurgy, and celestial mechanics. He would often summon Laplace to discuss physics.
Aristotle tutored Alexander the Great. And he took over the world. For 2,000 years, that was the deal. 1-on-1 tutoring was the cheat code, and only the royals afforded it. Bloom proved it in 1984. 1-on-1 tutoring routinely lifts learners from the 50th percentile to the 99th.
@fleetingbits Standard Intelligence has some interesting results si.inc/posts/fdm1/
@EmmaQian_ @LilyMaeLazarus @FortuneMagazine Congrats, Emma! Super excited for what’s ahead!
Ecstatic to be supporting Nikola and the team!
DeepInfra has raised its $107M in Series B funding 🚀 AI is moving from training to production-scale deployment, and inference is becoming the system constraint. DeepInfra was built for this shift — scaling high-throughput inference for open-source and agent-driven workloads.

@TLiptay im curious if you have a comparison of different strategies you guys have tried out, including giving different models different weights
@LiamFedus Unproven assumptions are a big part of science. Isaac Newton wouldn’t have been able to come up with his laws of motion without this leap of faith
