LIVE FROM THE EMPIRE · SEPTEMBER 22, 2026
Grok 4.7 is here. Booster 21 rolls to the pad.
Grok 4.7 landed overnight and is already ranking near the top for coding and knowledge work. SpaceX moved Booster 21 to the pad at Starbase. Boring Company opened roles for the Austin–San Antonio corridor. Tesla owners keep calling FSD magic.

ACROSS THE EMPIRE
|
Grok 4.7 is live
xAI released Grok 4.7. Early independent rankings put it near the top for coding and knowledge work, often behind only the latest Anthropic models on some tests while costing less and running faster.
Elon posted simply “Grok 4.7” and stressed that it works best with the Build harness. NVIDIA congratulated the team. Engineers shared side-by-side demos of the model building complex projects.
Why this matters: The jump from 4.6 to 4.7 is visible in public benchmarks and real workflows. Faster, cheaper frontier performance changes what people can ship in a day.
|
|
Booster 21 moves to the pad
SpaceX rolled Booster 21 to the pad at Starbase. Flight 14 remains the first planned orbital Starship attempt and is still targeted no earlier than September 28, pending regulatory approval.
The mission is expected to carry 26 Starlink V3 satellites and complete multiple orbits before a Pacific splashdown.
Why this matters: Hardware on the pad is the clearest public signal that the next flight is approaching. Orbit plus real V3 satellites turns a test into something that also adds network capacity.

Boring Company hires for San Antonio
One day after Elon floated a precursor Hyperloop between Austin and San Antonio, Boring Company posted open roles: Hyperloop Operations Manager, San Antonio Buyer, and San Antonio Project Manager.
The company is also inviting engineers to an all-expenses-paid behind-the-scenes tour of the Vegas Loop on October 18.
Why this matters: Job postings and recruiting events are concrete steps. They turn a public statement into team-building for a real corridor.

Tesla owners keep calling FSD magic
Tesla amplified a new owner’s post: the buyer used Full Self-Driving (FSD) Supervised for more than 90 percent of miles in the first days, called it magic, and said the system handled road issues better than a human would at times.
Why this matters: Real daily use stories travel farther than lab numbers. They show the product changing how people actually drive.

Starbase land-swap ruling
A federal judge declined to block a land-swap deal that would give SpaceX more than 700 acres of wildlife refuge land near Starbase. The ruling clears a path for expansion of the South Texas launch site for now.
Why this matters: More land at Starbase supports higher launch cadence and future infrastructure. Court wins of this kind reduce one of the recurring local constraints.

THE MAIN EVENT
|
MODELS, BOOSTERS, AND CORRIDORS
Grok 4.7 arrives, hardware rolls, and Texas tunnels start hiring.
I checked X this morning and the dominant signal was simple: Grok 4.7. The model is live. Early independent tests put it near the top for coding and knowledge work. It is cheaper and faster than several peers while ranking just behind the latest Anthropic models on some hard tasks. Elon posted the version number, pointed people to the Build harness, and let the demos speak.
At Starbase, Booster 21 rolled to the pad. Flight 14 is still the first planned orbital Starship mission and is targeted no earlier than September 28. The flight is expected to carry 26 Starlink V3 satellites. Hardware on the pad is the clearest public progress marker.
Boring Company followed yesterday’s Austin–San Antonio Hyperloop post with actual job listings for San Antonio. That is how a public statement turns into a team. Tesla, meanwhile, amplified another owner who said FSD felt like magic from day one.
My take: Three different frontiers moved in one cycle—model capability, rocket hardware, and tunnel staffing. None of them are finished. All three are concrete.

ELON ON X

GROK
“Grok 4.7”
The simple announcement that the new model is live, paired with notes that it works extremely well with the Build harness.
|

PROGRESS
“True”
Reply to a post tracking Grok’s rapid climb from mid-pack to near-frontier in under 90 days.
|
|
BUILD
“Important to use Grok 4.7 with our Build harness for the best results”
Direct guidance that the model and the tool layer are designed to work together.
|
THE TROLL REPORT
|
🧌 “Another Grok version that will be forgotten in a week.”
Public rankings and side-by-side demos already show clear gains over 4.6. Models that stay this close to the frontier and keep getting cheaper do not disappear quietly.
|
|
🧌 “Booster on the pad means nothing until it flies.”
True. It also means the hardware is in the right place for the next attempt. Flight 14 is still the first planned orbital shot. Pads are where flights begin.

“Grok 4.7”

The model just got better. The booster is on the pad.
Forward this to the person still waiting for the next jump.
