Leasing compute to Anthropic signals xAI surrender in foundation model race
“This is effectively giving up. It's saying, you know, it doesn't know how to effectively use this compute capacity to train models, or if it did, it wouldn't be worth the expense because it would still be behind OpenAI. And anthropic, and so therefore it's now…”
xAI Is Compute-Inefficient and Brute-Forces Problems With Massive Compute
“XAI is an amazing team. And they, they've been able to achieve so much in so little time, but it's also well known in the industry that they're computer inefficient. They're so compute rich that, that they're throwing computer the other problem in many ways.”
Kantrowitz: xAI rented Colossus 1 compute cluster to Anthropic
“You just rented your AI warehouse Colossus One to Anthropic.”
Horowitz: Sam Altman is attempting to broker Pentagon-Anthropic peace deal
“Some of the other frontier AI labs like XAI and OpenAI are already now willing to work on the classified side, and you know, Sam Altman is attempting to broker a piece, essentially, and create a deal that perhaps Anthropik could join as well.”
Siegler: Microsoft and Amazon back multiple AI labs to stop Google
“I think these other major cloud players, at least the ones who have the rival clouds, specifically Microsoft and Amazon realize that yeah, they probably need to align around basically anyone who's not Google, right? They don't necessarily care if it, I mean, t…”
Siegler: xAI and SpaceX merger sounds likely and may be announced this week
“If they really do merge with SpaceX, which it does sound like now, is gonna happen, and may even be announced this week, which is insane how fast that that came together, if it comes together in that way.”
Kantrowitz: AI love bots will become a major consumer tech category
“But I think the bigger picture here is, you know, beyond that, that this is going to be a real use case that a lot of people are going to engage with. And I think they know this. And I think we're just at the very, very beginning here. I guess like one of the …”
Kantrowitz: Grok 4 beats all models on ARC-AGI by significant margin
“And then of course in the Arc AGI test, it outperforms Every model by a significant margin.”
Hidden system prompts in AI chatbots pose subtle ideological steering risks
“The thing is, what, all these chatbots have a, often hidden, system prompt, and they have an ideology, one way or the other. Sometimes, most of the times, not as overt as this, And that to me is the risk about these things becoming the last website is that you…”
Hanna says xAI uses methane generators to power its Memphis supercomputer
“I would also say that speaking about existing effects, there's also a lot of reporting coming out of Memphis right now, especially around the methane generators that XAI has been using to power a particular supercomputer there called Colossus there, and specif…”
Marcus: Grok 3 delivers minimal gains despite 10x compute
“So he built Grok three and by his own testimony, it was 10 times the size of Grok two. It's a little better, but it's not night and day, right? Grok two was night and day better than the original Grok. GPT four was night and day better than GPT three. GPT thre…”
Kantrowitz: Merging SpaceX and xAI is a high-risk, bad combination
“I think not a great combination if you ask me, especially, you know, SpaceX is highly regulated. It's a government contractor. XAI recently was, you know, bikini-fying people on, on Twitter. I think that's some sort of risk there.”
xAI Spent as Much on Grok 4 Reinforcement Learning as Pre-Training
“Grok IV spent as much on reinforcement learning as they spent on, on pre-training, which is unheard of.”
Levie: Multi-agent inference architectures will become an industry standard
“They have a model called Grok for Heavy that has multiple agents go off and execute basically the same task and then go, they go and review their answer for, Which answer they think is, these agents think are the best result. And so this is a great example of …”
Kantrowitz: Elon Musk has completely lost control of Grok's political alignment
“Elon, who's like, say what you want about him, one of the most successful tech entrepreneurs of our time, if not the completely lost control of his AI.”
Patel: xAI is slightly behind leading labs but has high compute per employee
“I think they're a serious competitor. I just don't know much about what they're going to do next. I think they're like slightly behind the other labs but they've got a lot of compute per employee.”
Grok's system prompt suffered an unauthorized change on May 14, xAI says
“It was on May 14th at approximately 3:15 a.m. Pacific Standard Time, an unauthorized modification was made to the Grok response. Bots prompt on X.”
Musk's merger of X into xAI was brilliant financial engineering
“I think it was a great buy for Elon Musk from a business standpoint because he still owns it, no cash changed hands, and he got to just label A valuation that he wanted to on a property that is not worth that. So that kind of financial engineering, I think we …”
Kantrowitz: SpaceX's xAI acquisition valued SpaceX at $1.25 trillion in February
“The company's acquisitions of Musk's XAI company valued SpaceX at 1.25 trillion in February.”
Kantrowitz: X data is definitely being used to train xAI models
“All your X data was going to be used to train these models anyway, and now it definitely is, and there's no getting away from it.”
Hendrycks: I earn $1 a year from xAI and $12 from Scale
“My appointment at XAI, I get a dollar a year. At Scale, I've at Scale AI, I've increased my salary exponentially to where I get 12 dollars a year, a dollar per month from Scale.”
Scaramucci discloses personal investments in xAI and SpaceX
“Full disclosure, I am a investor in XI, XAI. I was an investor in Twitter. It got converted into XAI. It's, you know, sort of Twitter merged with Grok now. I have a small investment in XAI prior to that. I have an investment in SpaceX, me personally.”
