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.

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 639 aircraft now equipped. 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 through the SpaceXAI Realtime 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 🚀

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.
SpaceX has just introduced Grok Voice 3.0
"It's the world’s most intelligent speech-to-speech model. It sets a new record for resolving customer support calls, has class-leading latency at under one second, and costs less than other frontier models. It's also cheaper to run than comparable models. Artificial Analysis measures what each model costs to complete a task in its Big Bench Audio run, and Grok Voice 3.0 comes in under both GPT-Live-1 (Astra, Medium) and GPT-Realtime-2.1.
Grok Voice 3.0 handles millions of conversations a day in Tesla vehicles. Drivers can use Connectors for simple requests like checking their calendar or answering an email, and Grok Bot for bigger tasks like ordering a coffee or booking dinner—all completely hands-free (see it on X). Grok Voice 3.0 also powers Grok Bot’s voice mode."

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.

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! 👏

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 month. Several buildings 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.
🤖 Made with AI

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

I have been a posting slug!
How about that launch triple header last week: Starship, Crew 13, and Heavy!!!
Terrestrial low band spectrum acquisition and FCC approval for Starlink Mobile constellation!
And I am always relieved, grateful and proud when we complete a crew mission— welcome home to Mother Earth Crew 12!

Thank you on behalf of the amazing people of SpaceX, Tesla, Neuralink and Boring Company, without whom anything I have done would have been impossible

There is a bright and exciting future for humanity ahead – and space is fundamental to that future.
To achieve this, space safety must be done right. We encourage every operator to not only share ephemeris data proactively the same way Starlink already does, but to also adopt the high standards of space safety that SpaceX and Starlink use every day → starlink.com/updates/space-s…
