“This weekend, the @xAI team brought our Colossus 100k H100 training cluster online. From start to finish, it was done in 122 days. Colossus is the most powerful AI training system in the world. Moreover, it will double in size to 200k (50k H200s) in a few months. Excellent…”

“The @xAI MACROHARD project will be profoundly impactful at an immense scale 😉 Our goal is to create a company that can do anything short of manufacturing physical objects directly, but will be able to do so indirectly, much like Apple has other companies manufacture their [@cb_doge] Elon Musk is literally painting MACROHARD on the roof of the Colossus II supercomputer cluster in Memphis. Here’s what it’s going to look like:”

“1.21 Gigawatts of training @xAI !!! https://t.co/KF5ANCUcEU [@muskonomy] 🚨NEWS: Today NVIDIA CEO Jensen Huang calls Elon Musk “the most world-class builder we have in the country.” He says Elon’s new Colossus II supercomputer could scale to 500,000+ GPUs maybe the first to hit a gigawatt of compute.”

“Colossus 2 will be the first Gigawatt AI training supercluster [@teslaownersSV] 🚨 BREAKING: xAI just received 168 Tesla Megapacks to power Colossus 2 their second AI data center. That’s massive energy storage. Enough to run an entire neighborhood now fueling AGI. Tesla + xAI = The future of power-hungry intelligence.”

“We need to focus on finishing Colossus 2 and ensuring it is extremely stable, then will build the water recycling plant [@xAIMemphis] xAI is committed to building a state-of-the-art water recycling plant in Memphis. This plant will protect billions of gallons of water each year. The team is currently prioritizing other more immediate projects at the site but our plans to build the water plant have not”

“Colossus 2, built by @xAI, will be the world’s first Gigawatt+ AI training supercomputer [@MichaelDell] Great visit to @xai with @BrentM_SpaceX @nmswede today! It’s amazing to see what you guys are accomplishing and we couldn’t be prouder to be part of it. I very much enjoyed it. Onward 🚀”

“230k GPUs, including 30k GB200s, are operational for training Grok @xAI in a single supercluster called Colossus 1 (inference is done by our cloud providers). At Colossus 2, the first batch of 550k GB200s & GB300s, also for training, start going online in a few weeks. As Jensen [@ajtourville] Nvidia CEO Jensen Huang on Elon Musk and @xAI “Never been done before – xAI did in 19 days what everyone else needs one year to accomplish. That is superhuman – There's only one person in the world who could do that – Elon Musk is singular in his understanding of engineering.””

“Asked and answered [@grok] @sama @0x_Osprey @NGDreaming @elonmusk Choosing between Sam Altman and Elon Musk for AI leadership is tough, as both drive humanity's future differently. Altman's innovation, like ChatGPT and Stargate, makes AI accessible but raises profit-driven concerns. Musk's focus on safety and ethics via xAI and Colossus”

“@yeonwoo1102 @BIMBOSATTVA_ We are literally painting MACROHARD on the roof of the Colossus II supercompute cluster in Memphis big enough so you can read it from space”

“@techdevnotes We understand what needs to be done and will get pretty close by April and roughly similar by May, so probably better by June when Colossus 2 is fully operational. By then, like a self-driving car that drives perfectly, it will be hard to tell the difference between the leading”
