Deloitte on Monday announced a deal to bring Anthropic's artificial intelligence assistant Claude to more than 470,000 of its employees around the globe.
The rollout will be Anthropic's largest enterprise deployment ever, building on a partnership that the two companies first unveiled last year.
Deloitte, which offers consulting, tax and audit services, is one of the 300,000 business customers Anthropic has amassed in the four years since the startup's founding.
"We are both investing a significant amount in this partnership, whether that's financial or whether it is just simply the engineering resource that we're going to put into this as well," Paul Smith, Anthropic's chief commercial officer, told CNBC in an interview.
The companies declined to disclose the financial details of the deal.
Deloitte will build out and deploy different Claude "personas" for different groups of employees, ranging from accountants to software developers, over the next several months. Staffers can also get support from specialists within Deloitte's Claude Center of Excellence, which is designed to help teams deploy and benefit from the technology more quickly.
