xAI asked data center providers how long it would take to get 100,000 GPUs running as one cluster. The answer was 18 to 24 months. At the Grok 3 launch Elon Musk said: "18 to 24 months, that means losing as a certainty. So the only option was to do it ourselves." So they found an empty Electrolux factory in Memphis and brought in "trailer after trailer of generators." They leased about a quarter of the mobile cooling capacity in the U.S. and used Tesla Megapacks to smooth out the power. Colossus was built in 122 days. 92 days later it had doubled to 200,000 GPUs. Both happened before the earliest date they had been quoted. Today Colossus 2 alone has 550,000 GB200 and GB300 GPUs, according to Elon Musk's own post (Sept 25, 2026). When the quote says two years, you can wait, or you can break the wall and build it yourself.

.@xai's Grok-4.7 and @Zai_org's GLM-5.3 are now in public preview on Snowflake Cortex AI across • Snowflake CoCo • Snowflake CoWork • Cortex AI Functions • Cortex Inference • Cortex Agents More model choice for coding, knowledge work and long-running agent tasks, right next to your governed data

xAI launches Team Bots shared AI teammates for businesses. * Team Bots learn team workflows with custom skills, plugins, secure credentials, and persistent memory. * Already used internally at SpaceXAI for sales prep, engineering coordination, data queries, customer feedback, and hiring. * Now in public beta for Teams and Enterprise, with Slack integration and privacy for individual conversations. AI teammates are becoming part of everyday business operations.

xAI is doing Grok Bot Galaxy all week. There are sessions for engineering, product, founders, sales, support and marketing. If you’re trying to understand Grok Bot, watch these. I will. I’m particularly interested in Thursday’s marketing sessions because I’ve spent the last week going through 863 public Grok Bots and testing what marketing work is actually worth handing off. They’ll show what’s possible. Friday I’ll show you what I’d actually use.

xAI really cooked with this. You can create a Grok voice agent with a real phone number in the xai console in 2 mins. Found this while randomly exploring. Create a Customer support bot with MCPs, tools, web search. in Two minutes. Crazy. @elonmusk

xAI needs to fix their inference speed before grok 4.7 because grok 4.6 is supposed to be fast and yet we're experiencing slow performance due to demand so if they release 4.7 which they said is gonna be slower already the experience is gonna be pretty bad.
