Elon Musk He also announced that xAI’s upcoming model, Grok 5, will begin training very soon. MINISTÉRIO DAS COMUNICAÇÕES, CC BY 2.0 , via Wikimedia Commons Share Tweet Elon Musk has reiterated a rather shocking tidbit about xAI’s impressive scores at the ARC-AGI benchmark. He also announced that xAI’s upcoming model, Grok 5, will begin training very soon.
xAI results on the ARC-AGI benchmark In a recent post on social media platform X, Greg Kamradt, President of the ARC Prize Foundation, noted that Grok 4 has been used in two SOTA submissions to the ARC-AGI V1 and V2 benchmarks. The submissions, which were the best that the foundation has encountered to date, were done using xAI’s large language model, Grok 4.
As per Kamradt, when asked about why the submissions were done using Grok 4, the authors stated that “It was the best model I used in testing.” Musk was evidently proud of this accomplishment, though he also highlighted that these accomplishments were attained with just Grok 4. This suggests that once Grok 5 is in the picture, xAI’s lead in the AI sector could become notable.
Grok 5 incoming Elon Musk has shared a number of tidbits about Grok 5 as of late. In recent comments on X, the Tesla and SpaceX CEO stated that he believes Grok 5 has the potential to actually reach artificial general intelligence (AGI). This suggests that Grok 5 would be nothing short of a monster, as it could be capable of matching or surpassing human-level intelligence across tasks such as thinking, reasoning, and other domains by a substantial margin.
Grok 5 may also be coming soon. As per Musk in another post on X, xAI will be starting the training of Grok 5 in a few weeks. Musk definitely seems to be highly optimistic about the capabilities of Grok 5, with the CEO stating late last month that the update would be coming before the end of the year and that it will be “crushingly good.

Elon Musk Tesla called ‘biggest meme stock we’ve ever seen’ by Yale associate dean Published 21 seconds agoon September 17, 2025 Credit: Tesla Tesla (NASDAQ: TSLA) is being called “the biggest meme stock we’ve ever seen” by Yale School of Management Senior Associate Dean Jeff Sonnenfeld, who made the comments in a recent interview with CNBC.
Sonnenfeld’s comments echo those of many of the company’s skeptics, who argue that its price-to-earnings ratio is far too high when compared to other companies also in the tech industry. Tesla is often compared to companies like Apple, Nvidia, and Microsoft when these types of discussions come up. Fundamentally, yes, Tesla does trade at a P/E level that is significantly above that of any comparable company.
However, it is worth mentioning that Tesla is not traded like a typical company, either. Here’s what Sonnenfeld said regarding Tesla: “This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same.
I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.” Many analysts have admitted in the past that they believe Tesla is an untraditional stock in the sense that many analysts trade it based on narrative and not fundamentals.
Ryan Brinkman of J.P. Morgan once said: “Tesla shares continue to strike us as having become completely divorced from the fundamentals.” Dan Nathan, another notorious skeptic of Tesla shares, recently turned bullish on the stock because of “technicals and sentiment.” He said just last week: “I think from a trading perspective, it looks very interesting.
” Nathan said Tesla shares show signs of strength moving forward, including holding its 200-day moving average and holding against current resistance levels. Sonnenfeld’s synopsis of Tesla shares points out that there might be “a little too much emphasis on the magic wand of Musk.” Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever This could refer to different things: perhaps his recent $1 billion stock buy, which sent the stock skyrocketing, or the fact that many Tesla investors are fans and owners who do not buy and sell on numbers, but rather on news that Musk might report himself.
Tesla is trading around $423.76 at the time of publication, as of 3:25 p.m. on the East Coast. Elon Musk Elon Musk teases the capabilities of the Tesla Roadster once again Published 3 hours agoon September 17, 2025 Elon Musk has once again teased the capabilities of the Tesla Roadster, fueling the anticipation that many have for the vehicle, despite it still having no public production or delivery date.
The Roadster is among the most anticipated vehicles in the automotive sector currently, and as Tesla has teased its capabilities, from a lightning-fast 1.1-second 0-60 MPH acceleration to potential hovering with cold-gas thrusters, people are eager to see it. Although the design seemed to be finalized, there was still more work to be done.
Earlier this year, as Tesla was showcasing some of the Roadster’s capabilities to Musk, he stated that it was capable of even more. This pushed back its production date even further, much to the chagrin of those who have been waiting years for it. Musk continues to tease us all, and as we sit here waiting hopelessly for it to be revealed, he said today that it is “something special beyond a car.
” The new Roadster is something special beyond a car — Elon Musk (@elonmusk) September 17, 2025 Musk’s words were in response to a video posted by Tesla China, showing the Roadster in a new promotional video created by a fan. The Roadster was planned to be released in 2020, but here we are in 2025, and there is still no sign of the vehicle entering production.
However, Tesla did say earlier this year that it would host a demo event for the Roadster, where the company would showcase its capabilities. Lars Moravy said earlier this year: “Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.
” Tesla exec gives big update on Roadster, confirming recent rumor The delays have been attributed to “radically increased design goals” for the vehicle, which have, without a doubt, improved its capabilities, but at the same time, we just want to know if it’s ever going to come. Tesla can always make it “better,” but at what point do you say, “Okay, it’s time to show this thing off.
” They could always build another, even more capable supercar in the next ten years. Elon Musk Elon Musk says xAI has a chance to reach AGI with Grok 5 The comment came after Grok 4 posted strong results on the ARC-AGI benchmark. Published 6 hours agoon September 17, 2025 (Credit: xAI) Elon Musk suggested this week that his artificial intelligence startup xAI has the potential to reach artificial general intelligence (AGI) with the next version of its large language model, Grok 5.
The comment came after Grok 4 posted strong results on the ARC-AGI benchmark, which tests reasoning and problem-solving ability. Musk sees Grok 5 as AGI candidate In a post on X, user @amXFreeze shared the latest results of the ARC-AGI leaderboard, which showed Grok 4 outpacing rival systems such as OpenAI’s ChatGPT in problem-solving and open program synthesis tasks.
Musk reacted to the performance by stating that “I now think xAI has a chance of reaching AGI with Grok 5. Never thought that before.” Artificial General Intelligence (AGI) refers to an AI system that is capable of matching or surpassing human-level intelligence across tasks such as thinking, reasoning, and other domains by a notable margin, as noted in a report from Benzinga.
AI companies today are actively pursuing AGI. xAI’s speed While xAI was only established in March 2023, the startup has grown aggressively. Since its founding, it has rapidly risen in the AI segment and its Grok large language model has become a mainstream option for everyday users, especially on social media platform X.
The company is still growing aggressively, and it is currently expanding its Colossus supercomputer cluster in Memphis. During xAI’s Engineering Open House event in San Francisco in its early days, Elon Musk highlighted that speed would be the company’s primary competitive edge. To highlight this, Musk stated that “No SR-71 Blackbird was ever shot down and it only had one strategy: to accelerate.
” So far, xAI is definitely playing this role very well.
