Deloitte will make Anthropic’s Claude available to more than 470,000 people across its global network and establish a Claude Center of Excellence, the two companies announced Monday. The alliance, which Deloitte and Anthropic describe as Anthropic’s largest enterprise AI deployment to date, includes co-creating a certification program for 15,000 Deloitte professionals and building compliance tools for regulated industries such as financial services, healthcare and public services. Financial terms were not disclosed.

The same day, Australia’s Department of Employment and Workplace Relations confirmed Deloitte will repay the final installment of an about A$440,000 contract for an independent assurance review published in July. The Australian Financial Review reported in August that the review contained multiple citations to non-existent academic reports and a fabricated reference to a court decision in a robodebt case. A corrected version was uploaded to the department’s website last week. Deloitte added a note in its appendix acknowledging that part of the report used an Azure OpenAI GPT-4o tool chain licensed by the department.

Deloitte said the matter had been resolved with the client. The amended report states that the update does not affect the report’s findings or recommendations. The department said the substance of the review is retained. Labor senator Deborah O’Neill said Deloitte has a “human intelligence problem” and that the refund looks like a partial apology. Christopher Rudge, the University of Sydney academic who first highlighted the errors, said the report contained hallucinations and that several fake references were replaced rather than one, suggesting the claims in the body were not tied to any single source.
