Musk donates $2 billion to send Grok 4 to Mars! 200,000 GPUs to build a universal brain, generating 3D black holes with a single command.
Within 72 hours of its release, Grok 4 has taken Silicon Valley by storm! The first public demo left everyone in awe, with the ability to deploy a game in just 2 minutes and generate a complete animation with a single command.
Today marks the two-year anniversary of xAI, and Musk's SpaceX has announced a $2 billion investment, reportedly aiming to send the model to Mars in the future.
One command generates an entire animation, and a game can be deployed in just two minutes!
Just 12 hours after the release of Grok 4, AI developer McKay Wrigley experienced it firsthand and exclaimed, “It's insanely powerful!”
In a single request, Grok 4 Heavy generated a complete animation, seamlessly transitioning from a crowd walking to a bird's-eye view, demonstrating remarkable understanding and execution capabilities that other models cannot match.
Prompt: Create an animation of a crowd of people walking to form “Hello world, I am Grok” as the camera changes to a bird's-eye view.
It can even perform like a military parade, marching in perfect unison:
This 3D video went viral online, with over 3.5 million views.
AI startup Replit's Matt Palme deployed a game in just 2 minutes!
Using Grok 4 to write code, and through Three.js and GLSL shaders, user Techartist achieved an interactive 3D simulation and visualization of a black hole.
The details in the event horizon, star field, and accretion disk are astonishing, with effects that are hard to believe!

Grok 4, trained with 200,000 GPUs, is truly powerful!
After the launch, the official technical report for Grok 4 was finally released.
The world's smartest AI
100x scaling reinforcement learning
As the world's smartest AI model, the xAI team believes that Grok 4 has the foundation to fully understand the universe.
This is the result of scaling reinforcement learning.
As is well known, Grok 4 has 100 times the computing power of Grok 2 and completed RL training on a Colossus cluster consisting of 20 GPUs.
Previously, on Grok 3, the xAI team achieved pre-training of the next token at an unprecedented scale.
Furthermore, in the development of Grok 3 Reasoning, they proved that it is entirely possible to significantly expand the scale of reinforcement learning training in the future.
The birth of Grok 4 proves that the team is on the right track.
Innovations across the entire technology stack have increased the training computing efficiency of Grok 4 by 6 times.
At the same time, the research team has also carried out large-scale data collection work, expanding the training data available for verification from mainly mathematics and programming to more fields.
Not only that, but Grok 4 has learned to use native tools through RL, greatly improving its thinking ability with the help of code interpreters and web browsing tools.
As can be seen, in the human final exam (HLE), Grok 4's score with tools broke the SOTA record, setting a new record of 50.7%.
Grok 4 Heavy breaks HLE
Grok 4 Heavy is referred to as the multi-agent version, and its performance has been significantly improved after scaling tests.
A single model can simultaneously consider multiple hypotheses and ultimately consolidate them into a reliable and accurate answer.
In multiple benchmark tests, the Grok 4 series models have all broken SOTA records.
Notably, on the ARC-AGI V2 benchmark, it outperformed all closed-source top models with a score of 15.9%, doubling the performance of Claude Opus 4.
In the Intelligent Agent Vending-Bench benchmark test, Grok 4 demonstrated superior earning capabilities, far surpassing all models and humans.
In terms of IQ, Grok 4 is relatively weaker, scoring 136 on the Mensa IQ test, just behind Claude 4.
In the third-party programming benchmark Aider test, Grok 4 ranked fourth with a 79.6% accuracy rate and a cost of nearly $60.
Since xAI officially announced Grok 4 on July 13, 2023, two years have passed.
During this period, from Grok 1 to Grok 1.5, Grok 2, Grok 3, and now the “most powerful” Grok 4, Musk's xAI has quickly risen to the pinnacle of AI.
Co-founder Toby Pohlen posted again to celebrate xAI's two-year anniversary.
SpaceX invests $2 billion
to send Grok to Mars
Just moments ago, the Wall Street Journal reported that SpaceX has agreed to invest $2 billion in xAI.
This amount is nearly half of xAI's most recent equity financing round.
This isn't the first time Musk has done something like this.
He has long leveraged his various companies to advance xAI.
For instance, earlier this year, he merged xAI with X—one an AI startup and the other a widely influential social media platform.
This merger valued the new company at $113 billion!
This investment from SpaceX is part of xAI's $5 billion equity financing round.
This is not only SpaceX's first investment in xAI but also one of the largest investments in SpaceX's history.
Moreover, SpaceX has supported Tesla in its early stages and Musk's tunnel company, The Boring Company.
When acquiring Twitter (X), Musk requested a $1 billion loan from SpaceX.
SpaceX currently has over $3 billion in cash on hand.
The company rarely invests in external businesses. Its last major investment was in 2021, when SpaceX acquired a satellite communications company for $524 million.
The Wall Street Journal reported that Grok provides customer support functions for SpaceX's satellite internet service, Starlink.
Some investors have suggested that SpaceX and xAI may have more commercial collaborations in the future.
Netizens predict that the Grok model may one day be sent to Mars.
xAI valued at $200 billion? Musk denies
Prior to this funding revelation, Bloomberg reported yesterday that xAI is in funding negotiations with a valuation of up to $200 billion.
Previously, xAI had raised $10 billion, with debt and equity each accounting for half.
Currently, xAI is planning to raise another $10 billion.
The urgency to secure such a large amount of funding stems from xAI's high operational costs. Bloomberg previously reported that xAI burns through $1 billion per month during Grok's training phase.
In response, Musk himself denied the claims, stating, “We have sufficient funding and are not seeking a new round of financing.”
