Robotaxi went continuous. Agents reached the desktop. Grok rewrote its training stack. Robotaxi went continuous. Grok Bot reached the Mac. SpaceX committed $74 billion to two AI campuses.

[The last time something like this happened](https://aelon-g.com/aelgerw2), investors had a chance to turn a small stake of $10,000 into as much as $366,000 in just 14 months. ACROSS THE EMPIRE · WEEK IN FIVE MOVES Grok 4.8 got a new chassis xAI threw out JAX and SGLang and wrote a new reinforcement-learning and inference stack in C/C++, a detour Musk said cost extra time. Pre-training is finished, the model is in RL, and the evals are climbing. A soft rollout to Bot users was promised for the week. **Why this matters:** Most labs ship a patch. This one got a new engine bay, and every model after it rides on the same rails. Robotaxi went continuous The Robotaxi account says every city it serves now runs around the clock, and Musk put the number at 168 hours a week. Austin's zone had grown by more than 60% on Monday, and San Antonio came online. **Why this matters:** Utilization is where the money actually moves. One fleet, one capital base, a clock that no longer stops. Grok Bot left the chat On a Mac the assistant now reaches Messages, Mail, Notes, Calendar and a handful of other apps. Maye Musk pointed it at a folder of 2,000 photos and it finished in about five minutes. Musk answered with one instruction. **Why this matters:** The agent stopped being a browser tab. Now it works the machine the reader already sits at. $74B committed for compute SpaceX put more than $74 billion behind two supercomputing campuses, about $24 billion at Starbase and roughly $50 billion for the Arizona site. Water and power deals ride along, and Ship 42 reached the pad the same week. **Why this matters:** Frontier training eats land and electrons the public grid cannot hand over on demand. SpaceX is laying both down beside the rockets. Grok already inspects parts Ars Technica reported on Monday on a talk by launch chief Kiko Dontchev at UP.Summit: an inspector with a borescope catches about 94% of foreign object debris, and Grok reading the same video catches 99.9%. The tool is already in the factory, not in a pilot. **Why this matters:** A single stray fragment can end a mission. About six points of catch rate is risk off the manifest. THE MAIN EVENT · WEEKEND SYNTHESIS SATURDAY Five days. One tighter stack. Monday brought the small concrete one: a reported 99.9% catch rate for Grok on debris inside rocket parts, against about 94% for a human with a borescope. Friday brought the bigger one. The same assistant could sort a photo library, read mail and change a calendar on a Mac. Between those two points the training stack was rebuilt and the robotaxi clock stopped stopping. Under all of it sits compute. SpaceX named a price this week, more than $74 billion across two campuses, and paired it with the water and power deals that make the sites workable. Ship 42 went to the pad while the paperwork moved. **My take:** The vertical is no longer a slogan. The same company that builds the rockets is rewriting the training stack, deploying the agent on the user’s desktop, and locking down the power required for the next generation of models. The pieces now touch each other. ELON ON X · WEEK HIGHLIGHTS FOUNDATIONS “Grok 4.8 will bear no resemblance to 4.7 (thankfully). It is not yet incredible, but, this time, the foundations are built right” The stack is new, the rollout is promised, the old tools are gone. UPTIME “Robotaxi works 168 hours a week” Every city the service runs in is continuous now. The clock is no longer the constraint. TASKS “Give Grok @Bot your most laborious tasks!” His answer to a 2,000-photo sort that took minutes. Short, and meant to be followed. THE TROLL REPORT 🧌 “Nothing moved this week” The stack under Grok was replaced. Robotaxi stopped closing. The agent learned to drive a Mac. SpaceX committed $74 billion to two campuses. 🧌 “It is still just demos” Grok reads borescope video at 99.9%. Robotaxi never closes. The bot cleared 2,000 photos while its owner went back to scrolling. “The road ahead is long and we are still in the first mile, although it may seem otherwise” \- Elon Musk Foundations rewritten. Clocks continuous. Agents on the desktop. One week. Five moves. The stack is tighter than it was on Monday.
