Yann LeCun describes xAI as a 'failure' and cautions about a potential AI bubble.
Yann LeCun has openly expressed his skepticism, and his latest criticism targets one of the world's most valuable companies. According to LeCun, the founder of AMI Labs and former chief AI scientist at Meta, Elon Musk’s xAI is a “kind of a failure” that will struggle to compete with OpenAI and Anthropic, as reported by CNBC.
His concerns focus on personnel issues. “The founding team has left, or was fired,” he stated, acknowledging some uncertainty, and he added that Musk now finds it “very, very difficult” to attract top AI talent “because he’s kind of, you know, not behaved in sort of very good ways” toward the previous team.
LeCun also criticized the financial aspects of xAI. He mentioned that the company has “huge infrastructure” which it leases to others, noting that this is “the only way he can recoup the cost.”
There is some validity to his comments regarding infrastructure. xAI's Colossus data centers in Memphis are partially rented out to competitors: Anthropic and Google both lease computing power there, with Google paying around $920 million per month to SpaceX.
The context is significant. In February, Musk merged SpaceX with xAI, valuing the combined entity at $1.25 trillion. In the first quarter, SpaceX’s AI division, which includes xAI, reported an operating loss of $2.5 billion.
LeCun's broader assertion concerns the entire industry. He warned that AI services are becoming more costly to operate than what labs can charge for, and this disparity is masked by investor support. “The prices are going up… but the cost of running them is going down, but not nearly fast enough. And so all of those companies are losing money, and basically, the use for most people is funded by the investors. That can’t go on for very long,” he said. He further added that labs “are going to have to increase prices, they’re going to have to cut costs, or there’s going to be a big bubble explosion.”
This is not an isolated concern. OpenAI’s Sam Altman has recently identified AI costs as a “huge issue,” and enterprise spending on the technology is facing increased scrutiny.
It's crucial to consider that LeCun is not an impartial observer. In March, his startup AMI Labs secured approximately $1 billion based on the belief that the large language models sold by OpenAI, Anthropic, and xAI are not viable. He argues that the future lies with “world models,” positing that “we’re not going to have generalized reliable agentic systems” without them.
Thus, his warning of a potential bubble and his critique of xAI also serve as a promotion for his own approach. While the problem he describes regarding unit economics is widely recognized, it also makes him less objective in delivering this critique. Additionally, he and Musk have had longstanding disagreements; Musk has previously labeled him as “out of touch with AI for a long time.” There were no comments from xAI and SpaceX.
