@herbertong @CernBasherd both have 220k GB300s with 800 gig nics configured for training. Gun Range will have the same. Spam (used to house Hormel products) will have ~200k GB300s, but configured for inference, so much simpler networking and less than half the fiber.

I walked the whole Colossus 2 site around midnight and again this morning.

Good progress by the SpaceX team and contractors. Gun Range is tracking to be operational by end of November and Spam in December.

Congrats to the @SpaceX team on over 700 Falcon 9 flights!

Tesla is celebrating Halloween this year by having a Cybercab autonomously drive around Austin with skeletons inside haha 🎃

Grok @bot can now call someone or a business for you, make a request on your behalf, take notes on the response and send you a note summarizing the conversation!

Underrated life advice: Be more enthusiastic. One of the most attractive traits is genuine enthusiasm. It's energizing to spend time around people who show real excitement for life. For people, ideas, and tiny moments. It takes courage to care so openly. Enthusiasm is contagious.

Falcon 9 launches USSF-481 to orbit from pad 4E in California

We will post our Q3 2026 financial and operational results on October 20, 2026. We will host a live audio-only webcast at 3:30 p.m. CT the same day → ir.spacex.com/updates/releas…

United Airlines has just introduced an awesome new @Starlink Wi-Fi tracker that not only makes it easy to find out if your flight has Starlink, but also gives real-time Starlink installation progress for their fleet.

United has now installed Starlink on 43% of its fleet, with ed. It even breaks down what percent of flights from each hub have Starlink, as well as installation progress by aircraft type. Really cool!

SpaceXAI’s Grok Voice 3.0 is the new leading Speech to Speech model, debuting at #1 on the Artificial Analysis Speech to Speech Index at 86.9, while also being competitive on latency

Grok Voice 3.0 is @SpaceXSI 's successor to Grok Voice 2.0, a Speech to Speech model available altime API at $0.08 per minute. We evaluated Grok Voice 3.0 with the Rex voice through the SpaceXAI Realtime API.

Key takeaways:

➤ Speech to Speech Index: Grok Voice 3.0 debuts at #1 at 86.9, ahead of GPT-Live-1 (Astra, medium) at 83.2, Gemini 3.8 Live Extended Thinking (High) at 82.6 and GPT-Live-1 (Sol, low) at 80.1. It is up on Grok Voice 2.0 at 81.3 (+5.6 points) and Grok Voice 1.0 at 73.7 (+13.2 points), released just under six months ago. The Index averages Speech Reasoning (Big Bench Audio), Agentic Performance (Tau Voice), Arena Preference, and Task Success Rate

➤ Speech Agent Arena: Grok Voice 3.0 ranks #3 in preference at Elo 1070, behind Gemini 3.1 Flash Live Minimal (1100) and Gemini 3.8 Live (1088) and ahead of GPT-Live-1 (Sol, low) at 1057, and #1 on Task Success Rate at 94.8%, highest on the board, just ahead of Grok Voice 2.0 at 94.6%. Grok Voice 2.0 trails at Elo 1011

➤ Tau Voice: Grok Voice 3.0 takes the #2 spot on our Tau Voice benchmark implementation at 71.6%, behind GPT-Live-1 (Astra, medium) at 74.5% and ahead of Gemini 3.8 Live Extended Thinking (High) at 68.6% and GPT-Live-1 (Sol, low) at 59.3% - up from 56.5% for Grok Voice 2.0

➤ Big Bench Audio: Grok Voice 3.0 scores 98.5% on audio reasoning, ahead of Gemini 3.8 Live Extended Thinking (High) at 97.7% and Grok Voice 2.0 at 97.2%

➤ Speed: Average Time to First Audio on Big Bench Audio is 0.81 seconds for Grok Voice 3.0, well ahead of GPT-Live-1 (Sol, low) at 1.24s, GPT-Live-1 (Astra, medium) at 1.34s and Gemini 3.8 Live Extended Thinking (High) at 1.35s, though slower than Grok Voice 2.0 at 0.70s

➤ Cost: Grok Voice 3.0 costs $4.80 per hour of input audio, the same as Grok Voice 2.0. That is above GPT-Live-1 (Sol, low) at $4.47 and Gemini 3.8 Live Extended Thinking (High) at $3.50, cheaper than GPT-Live-1 (Astra, medium) at $5.83, and ~2.2x cheaper than GPT-Realtime-2.1 High at $10.75

Congrats to @elonmusk and the @SpaceXSI team 🚀

See below for more detail ⬇️

SpaceX says @Starlink call centers use Grok Voice to answer 20,000 customer calls per day. ~70% are resolved with no human in the loop, and one in four sales calls ends in a purchase before the caller hangs up. Grok Voice 3.0 also handles millions of convos a day in Tesla vehicles.

Prufrock-5 arrives at Morgan’s Inclusion Campus in San Antonio!

The 900,000 lb TBM will construct a 0.8-mile tunnel to provide safe, weatherproof and convenient transportation for people of all abilities to move throughout the campus.

Work is expected to begin following final permit approvals.

Introducing Grok Voice 3.0, the world’s most intelligent speech-to-speech model.

It excels at resolving customer calls, responds in under a second, and costs less than other frontier models.

Why this morning's CRS-35 launch glowed like a jellyfish 🪼

The ground at the Cape was still dark, but a few minutes after liftoff Falcon 9 climbed into direct sunlight. Up high the air is so thin that the exhaust plume balloons way out, and the sun, still below the horizon for everyone on the ground, lights it up from underneath. We get the same jellyfish effect on West Coast launches in the evening shortly after sunset. This is physics showing off.

A few more fun bits:
🔹 Dragon is taking the scenic route. At about 52 hours, this is the longest phasing to the ISS in Dragon's history, so docking is Thursday around 8 AM PT. The long trip mostly comes down to orbital mechanics as Dragon races to catch up with the station: it fires its engines several times to raise its orbit a little at a time, then lines up and docks on its own. In less than two weeks, we've gone from Dragon's shortest trip ever (Crew-13) to its longest (CRS-35), which shows how flexible Dragon is as a spacecraft.
🔹 Dragon's trunk is carrying the fourth and final set of the station's upgraded solar arrays. Each one unrolls like a yoga mat and puts out more than 20 kW. This pair finishes the station's power upgrade and is just one of many things CRS-35 is bringing to the ISS.
🔹 This is the 4th flight for this Dragon, C211, after CRS-26, CRS-29 and CRS-33. Reusability isn't just for boosters 😉

And a great 8th flight and landing for B1096. Incredible work by the Falcon and Dragon teams, and thank you to our NASA partners! 👏

Coolest pre-dawn launch I've ever seen 🤯🚀

The biggest development for $SPCX is in what I consider the most important Elon post ever.

SpaceX is completing MiniHard AI data centers every month in Q4. This WILL continue into 2027 and beyond.

Data centers mass produced means $26-76 billion per year of revenue added every s under construction at once. One finishing every month.

And each build takes five months—down from SpaceX’s own superhuman one year constructuon time. This is compared with two to four years for other builders. Five to ten times faster.

Faster, cheaper, better. That is the breakthrough. @elonmusk @herbertong @WR4NYGov

Three minihard data centers in 90 days. More than double compute of colossus 2 and colossus 1. Rubin minihards would add more compute than Colossus 2 EVERY month.

This is the last critical piece of the spectrum puzzle needed for SpaceX to provide complete phone coverage in America

RT @Gwynne_Shotwell: I have been a posting slug!

How about that launch triple header last week: Starship, Crew 13, and Heavy!!!
Terrestri…

@chamath To the casual observer, this won’t seem like much. To those who understand the spectrum wars, it’s an earthquake.

This will sound super crazy, but I see a path to SpaceX being worth orders of magnitude more than the current Earth economy
