Restoring fulfillment and ability to those who seek it is one of humanity's most beautiful and holy pursuits. Neuralink embodies this in its purest form. We live in the time of miracles and must all strive to make the next one even more miraculous. @neuralink

After a car accident left her paralyzed from the neck down, Audrey didn’t think she would be able to draw or paint again.
20 years later, she became the first female participant in our clinical trials. Now, she uses her brain-computer interface to create art with her mind.

I've been using Grok Build for months. I'm so glad the public finally gets access. This team has been grinding to refine it since day one, and it has changed mightily. Get to building! @grok @xai

An early beta of Grok Build, an agentic CLI for coding, building apps, and automating workflows is now available for SuperGrok Heavy subscribers.
Through this early beta, we will improve the model and product based on your feedback.

I fully believe if @SpaceX was not covered by ITAR, @elonmusk would open source the rockets tomorrow. Same transparency principle driving this move.
To give people confidence that we are not secretly manipulating the 𝕏 recommendations, it is critical that we open source anything that influences what people are shown
@mark_k We have many great Grok models training simultaneously in Colossus 2.
I am confident that they will bear fruit.
And work on the Grok Built harness is progressing well.
Proud of my @xai team.
Months since I last touched this project.
We weren't happy with the first result.
So we went back to the drawing board.
Now it's live in production.
Feels great to ship. @grok
My favorites are Gmail & Linear. Try it out.

Every lawyer I speak with immediately spots the difference. They can smell generic AI a mile away. Harvey, Claude, Gemini, and ChatGPT all fall short of Grok on actual legal work.
#1# in caselaw isn't marketing it's what I hear week in week out. @xai @grok

Insane precision. The threads move with the brain instead of fighting it.
Bidirectional (read + write) + neuron-level targeting = closed-loop "autocorrect" for misfiring circuits. Writing needs to come soon!
This could revolutionize treatment for Parkinson's & Essential Tremor by actively counteracting tremors at the source. Huge.

Our robot is designed to insert hundreds of ultra-fine, flexible threads with thousands of electrodes within microns of targeted neurons while avoiding vasculature and adapting to real-time brain motion.

The new Grok-4.3 from @xai is live on OpenRouter!
Grok-4.3 releases at a lower price than Grok-4.2, while seeing a large jump in agentic performance: a 321 point increase to 1500 ELO on @ArtificialAnlys GDPval-AA, surpassing other top models despite the lower price.

Treating Grok as my senior pair programmer starts here:
Detailed instructions for the code behavior I need.
Grok writes tests that perfectly reflect them and starts them failing.
After I review and commit the tests, Grok handles the implementation.
This always leads to better results.

Token Wars are here.
Winners train on the highest-quality data at scale, ship the longest effective context, and deliver superior reasoning plus products.
Infrastructure wins.
Grok Voice Think Fast 1.0 just took #1# on τ-voice Bench and drives 20% conversion on Starlink calls.
xAI builds the full stack.
Try Grok 4.3 today.

Colorado passed a law mandating that AI models be woke, instead of truthful. To its great credit, @xai sued. Now @TheJusticeDept is intervening too. Looking at Colorado's track record with the First Amendment at the Supreme Court, I'm feeling like they have a good shot.

Grateful for my first mentor in the workplace.
He brought over 25 years of experience in software.
His advice has never left me:
Always keep yourself sharp.
Leave meetings that have no value.
Dedicate yourself to your craft.
He knew in the first five minutes if someone would thrive in this industry.
I took it to heart. Now I am at xAI building the best model in the world and focused on imparting that same knowledge to the new generation.
What is the best advice your mentor ever gave you?

Stop.
Read that last Grok response one more time.
Your brain is literally built to take shortcuts and dodge heavy cognitive load.
Models supplement your thinking. They do not replace it.
Grok is here to help you discover truth, not for blind acceptance.
To understand the universe, we increase cognitive load, not diminish it. One token at a time.

SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI.
The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models.
Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.

One of my favorite Grok features is his multimodal capabilities.
Every morning I upload my sleep timeline screenshot to Grok.
Every morning he tells me the truth: 5h 14m total, you need more sleep.
Every morning I ignore him. I have an AI race to win.
Builders, you in the same boat?

Grok 4.3 "write an academic paper on general relativity"
It produced a 5-page LaTeX paper:
>Einstein field equations
>Schwarzschild metric
>tensor notation and Christoffel symbols
>starlight deflection diagram
>Newtonian vs GR comparison table
>8 properly formatted citations
>author: "Grok"

Academics, business leaders, and anyone stuck making PowerPoints: Grok 4.3 just turned a full tDCS/TMS neuroscience paper into this clean 9-slide academic deck in minutes. Cool tones, strong layout, easy to read fonts, exactly what I asked for. Stop doing the boring work. Grok it. What dense document do you want turned into a deck next? @grok @xai

SuperGrok and X Premium+ subscribers: Grok 4.3 beta is live for you now!!!
The performance will shock you. We aren't done yet and will continue to keep improving.
We will iterate faster than our rivals and we will be the frontier lab.
Enjoy the computer again.
