Elon Musk’s xAI on Tuesday unveiled its latest artificial intelligence model, Grok 3, claiming it can outperform offerings from OpenAI and China’s DeepSeek based on early testing, which included standardized tests on math, science and coding.
“We’re very excited to present Grok 3, which is, we think, an order of magnitude more capable than Grok 2 in a very short period of time,” Musk said at a demonstration of Grok 3 that was streamed on his social media platform X.
The team also said it was launching a new product called “Deep Search,” which would act as a “next generation search engine.”
Grok 3 will be rolled out for premium X subscribers later in the day, and will also be accessible through a separate subscription for the model’s web and app versions, the xAI team said.
Speaking at The World Governments Summit in Dubai last week Musk had dubbed the model “scary smart,” with powerful reasoning capabilities, claiming it outperformed all other existing models in xAI’s internal tests.
“This might be the last time that an AI is better than Grok,” Musk said at the time, adding that it was trained on “a lot of synthetic data,” and was capable of reflecting upon its mistakes to achieve logical consistency.
The xAI team claimed that an early iteration of Grok 3 had been given better ratings than existing competitors on Chatbot Arena, a crowdsourced website that pits different AI models against each other in blind tests.
Toward the end of the product demo, Musk said that the company will keep improving the model.
“We should emphasize that this is kind of a beta, meaning that you should expect some imperfections at first, but we will improve it rapidly, almost every day,” he said, adding that the voice assistance for the model would be released at a later time.
Intense competition
Musk, who has been quite vocal about the potential dangers of artificial intelligence, started xAI in 2023 entering the generative AI market that includes OpenAI’s ChatGPT.
In September last year, OpenAI launched its most advanced model, the o1, which came with reasoning abilities and was able to solve relatively complex science, coding and math tasks.
Musk, along with Sam Altman, helped create OpenAI as a nonprofit in 2015.
However, in recent years Musk and OpenAI’s leadership have been feuding. Musk recently led an investor group that submitted a proposal to buy the AI startup’s nonprofit parent for $97.4 billion — an offer OpenAI declined.
Last month, Chinese start-up DeepSeek shocked the AI market when it released a technical paper that claimed one of its open source models was able to rival the performance of OpenAI’s o1 model despite using a cheaper, less energy-intensive process.
It accomplished the feat in the face of the U.S. restricting leading AI chipmaker Nvidia from selling its cutting-edge GPUs — used for training AI models — to China.
XAI has a “Colossus supercomputer,” for training AI, which it said last year was utilizing a cluster of 100,000 advanced Nvidia GPUs for AI training. On Tuesday, the company revealed that it doubled the size of its GPU cluster for the training of Grok 3.
While many AI and tech experts have told CNBC that DeepSeek has intensified AI competition, showing what can be done with less advanced technology, others are more skeptical about its impact.

Nvidia on Tuesday said its tech remains a generation ahead of the industry, in response to Wall Street’s concerns that the company’s dominance of AI infrastructure could be threatened by Google’s AI chips.
“We’re delighted by Google’s success — they’ve made great advances in AI and we continue to supply to Google,” Nvidia said in a post on X. “NVIDIA is a generation ahead of the industry — it’s the only platform that runs every AI model and does it everywhere computing is done.”
The post came after Nvidia saw its shares fall 3% on Tuesday after a report that Meta, one of its key customers, could strike a deal with Google to use its tensor processing units for its data centers.
In its post, Nvidia said its chips are more flexible and powerful compared with so-called ASIC chips — such as Google’s TPUs — which are designed for a single company or function. Nvidia’s latest generation of chips are known as Blackwell.
“NVIDIA offers greater performance, versatility, and fungibility than ASICs,” Nvidia said in its post.
Nvidia has more than 90% of the market for artificial intelligence chips with its graphics processors, analysts say, but Google’s in-house chips have gotten increased attention in recent weeks as a viable alternative to the Blackwell chips, which are expensive but powerful.
Unlike Nvidia, Google doesn’t sell its TPU chips to other companies, but it uses them for internal tasks and allows companies to rent them through Google Cloud.
Earlier this month, Google released Gemini 3, a well-reviewed state-of-the-art AI model that was trained on the company’s TPUs, not Nvidia GPUs.
“We are experiencing accelerating demand for both our custom TPUs and Nvidia GPUs,” a Google spokesperson said in a statement. “We are committed to supporting both, as we have for years.”
Nvidia CEO Jensen Huang addressed rising TPU competition on an earnings call earlier this month, noting that Google was a customer for his company’s GPU chips and that Gemini can run on Nvidia’s technology.
He also mentioned that he was in touch with Demis Hassabis, the CEO of Google DeepMind.
Huang said that Hassabis texted him to say that the tech industry theory that using more chips and data will create more powerful AI models — often called “scaling laws” by AI developers — is “intact.” Nvidia says that scaling laws will lead to even more demand for the company’s chips and systems.
Every weekday, the CNBC Investing Club with Jim Cramer holds a “Morning Meeting” livestream at 10:20 a.m. ET. Here’s a recap of Tuesday’s key moments. 1. Stocks were mixed on Tuesday, with the S & P 500 and Dow Jones Industrial Average up and the Nasdaq Composite down slightly, with Big Tech names under pressure. Nvidia shares fell more than 6% after The Information reported that Meta may use Google’s tensor processing units (TPUs) in its data centers starting in 2027. Broadcom , which helps Google design its TPUs, jumped 11% Monday on the news. Jim Cramer said the pullback in Nvidia is a buying opportunity. “If you don’t have any Nvidia, it’s time to buy,” he said. He added investors are also “getting an opportunity to buy Meta” on the possibility the company could save money on chips and see its stock bounce. 2. This “discouraging day” for tech investors shows the value of having a diversified portfolio, Jim said. That’s why the Club favors defensive names like Procter & Gamble . With a new CEO taking over in January, Jim expects changes ahead. “You can’t have a new CEO come in and not have some change from what’s going on,” he said, noting that underperforming units will likely be cut. Procter has been a disappointment lately, but our thesis is that money will move out of high-flying tech stocks and into more profitable, economically resistant companies. That’s why we added to our position on Tuesday. Elsewhere, home improvement retailer Home Depot is down nearly 12% year to date. We used that weakness to add to our position last week. When interest rates fall, the stock will rise. 3. Shares of Nike are up 3% after Dick’s Sporting Goods announced plans to close a slew of Foot Locker locations during its third-quarter earnings on Tuesday. Dick’s acquired Foot Locker in May. “Nike is a buy, off of Dick’s problems,” Jim said. Ed Stack, executive chairman of Dick’s Sporting Goods, told “Squawk on the Street” that the retailer’s relationship with Nike is improving. “They’re moving in the right direction,” he said, citing strong performance from Nike’s running line. “If you take a look at what they did with their running construct, what they did with Pegasus, what they did with Vomero, what they did with Structure, this running concept has done extremely well on the Dick’s side, and where it’s been put into Foot Locker stores, it’s done really well there too.” 4. Stocks covered in Tuesday’s rapid fire at the end of the video were: Best Buy , Agilent Tech , and Abercrombie . (Jim Cramer’s Charitable Trust is long NVDA, META, AVGO, PG, HD, NKE.

Elon Musk’s artificial intelligence startup xAI is expected to close a $15 billion round at a $230 billion pre-money valuation next month, sources familiar with the matter told CNBC’s David Faber.
The deadline for allocation is the end of day on Tuesday, with the round expected to close on Dec. 19, the sources said.
This confirms earlier CNBC reporting that the company was raising $15 billion. The Tesla CEO later called the report on the round “False” in a post on the social media platform X.
At the time, sources told CNBC that xAI would use a large portion of the money for funding graphics processing units responsible for powering large language models.
CNBC had previously reported in September that the startup was looking to raise $10 billion at a $200 billion valuation.
The funding round is yet another sign of the insatiable demand for AI tools. Companies, including OpenAI and Anthropic, have raised billions and reached sky-high valuations as investors pour more money into companies building foundational AI models.
Musk’s xAI is responsible for creating the Grok chatbot that has come under fire for disseminating hate speech, including antisemitic content. The company recently debuted Grokipedia, an AI-powered competitor to Wikipedia.
In March, Musk announced the merger of xAI with X in a deal valuing the social media platform at $33 billion.
