Anthropic Taps xAI-Linked Nvidia Infrastructure Despite Musk’s ‘Evil’ Jab at Claude
SAN FRANCISCO — Anthropic is running workloads on Nvidia supercomputing infrastructure associated with Elon Musk’s xAI, according to a Benzinga report, despite Musk’s public description of Claude as “evil.”
The development highlights an increasingly common dynamic in the AI industry: competitors who spar publicly over safety, ideology and market share often rely on the same constrained pool of high-performance computing resources behind the scenes.
Musk, who leads both xAI and Tesla’s AI efforts, has repeatedly criticized Anthropic and its flagship model on social media, at one point calling Claude “evil.” Musk was an early backer of OpenAI before departing and later suing the organization, and has positioned xAI’s Grok model as a less restricted alternative to rivals including Claude and ChatGPT.
Despite that public antagonism, the business realities of AI development appear to have brought the two camps into a pragmatic infrastructure relationship. Nvidia’s GPU clusters remain the essential backbone for training and running large language models, and demand for compute capacity continues to outstrip supply across the industry.
Anthropic, which has raised billions in funding from investors including Google and Amazon, has been expanding its compute footprint as it scales Claude for enterprise and consumer applications. The company has been competing with OpenAI and Google for market share.
xAI, meanwhile, built what it has described as one of the world’s largest GPU clusters at its Memphis, Tennessee, data center — a facility housing tens of thousands of Nvidia H100 and successor chips. Leasing excess capacity from such facilities is a common practice in the industry, as companies seek to offset the enormous capital expenditures required to build and maintain AI infrastructure.
The arrangement illustrates what industry analysts have noted is a defining tension in the AI sector: fierce rhetorical and competitive rivalries coexist with deep infrastructure interdependencies. Companies that publicly position themselves as rivals frequently share cloud providers, chip suppliers and even data center capacity.
Neither Anthropic nor xAI immediately responded to requests for comment on the specific terms of any infrastructure arrangement, according to the Benzinga report.
