How they deploy

Deployment model

Deloitte runs AI as a federation. Deloitte Global sets the AI program, the Trustworthy AI framework and the global alliances, such as the Oct 2025 Claude agreement announced by Ranjit Bawa, while member firms build and run their own tools and name their own AI leaders: Jim Rowan is US Head of AI, and Hayley McKelvey joined the Deloitte UK Executive as the firm's first Chief AI Officer on Jun 1, 2026, responsible for AI across client services and internal operations. Each business also runs its own AI platform: Audit & Assurance builds Omnia with internal engineering teams, consulting delivers through Ascend, and Deloitte Tax named its first chief products officer for AI-enabled offerings in Aug 2026.

Model providers

Deloitte's PairD assistant used GPT-3.5 as its base when it reached Deloitte Belgium in Feb 2024, and a Deloitte Australia report revised in 2025 disclosed use of Azure OpenAI. Deloitte said in Apr 2025 it would buy Claude licenses for training and certification, made Claude available across its network in Oct 2025, and built its Ascend Agentic Harness and secure software platform on Claude models. Gemini Enterprise was available to more than 25,000 Deloitte professionals by Apr 2026, and Google DeepMind gives Deloitte early access to frontier Gemini models. Zora AI is built on NVIDIA AI Enterprise and NVIDIA Llama Nemotron reasoning models, Deloitte said in Mar 2026 it would apply NVIDIA's Nemotron 3 models across the firm and its clients, and MyAssist gives Deloitte Australia staff a choice of models.

Data and infrastructure

Deloitte said in Oct 2023 that DARTbot runs in a dedicated, self-contained environment that does not use user input to train the model, and Deloitte Belgium said in Feb 2024 that PairD draws on Deloitte's internal knowledge in a private environment without using client data. In Mar 2026 Deloitte Consulting activated its own AI factory with NVIDIA, an NVIDIA GB300 NVL72 system and RTX PRO 6000 Blackwell servers built with HPE and Dell Technologies, to run Zora AI and Deloitte's internal generative AI assistant and to train practitioners. Omnia, Deloitte's audit platform since 2015, is a global cloud-based platform; Deloitte has not named the clouds under Omnia, PairD, MyAssist or its Claude deployment. Deloitte and Hewlett Packard Enterprise offer Zora AI for Finance on HPE Private Cloud AI, Zora AI can also run on Oracle Cloud Infrastructure (Oct 2025), and the client version of MyAssist runs on a client's own infrastructure with Azure, Google or AWS models. In Aug 2026 Deloitte US bought the business of Wavicle Data Solutions to add Databricks data engineering capacity.

Federated: Deloitte Global sets the AI program and alliances; member firms and businesses build their own tools and name their own AI leaders

Deloitte Touche Tohmatsu Limited, Deloitte Global, does not serve clients, and its member firms are legally separate, so Deloitte's AI program runs at two levels. Deloitte Global, under CEO Joe Ucuzoglu, has a Global AI leader, Nitin Mittal, and a global technology and alliances leader, Ranjit Bawa, who set the AI program and the model partnerships. Member firms add their own AI leaders, such as Jim Rowan as US Head of AI and Hayley McKelvey as Chief AI Officer on the Deloitte UK Executive from Jun 1, 2026, and each business runs its own AI platform: Omnia in Audit & Assurance, Ascend in consulting and Intela in tax.

Deloitte's AI workforce sits in three places: AI and engineering practices inside each member firm's consulting business, for which Deloitte publishes no global headcount; the Global Deloitte AI Institute under Beena Ammanath, which also runs the Deloitte AI Academy and AI Incubator; and platform teams inside each business, such as the Audit & Assurance engineers who build Omnia. Deloitte had upskilled more than 300,000 people through the Deloitte AI Academy by Aug 2026 and planned to certify 15,000 professionals on Claude.

Use cases

Deloitte runs AI in its own work through workforce assistants (Claude, PairD, MyAssist, eBuddy and Gemini Enterprise), audit tools in Omnia and DARTbot, engineering and delivery tools in Ascend and its M&A platform, tax tools such as the Intela Digital Assistant and Tech Writer, and learning, marketing and staffing assistants, and it sells agents such as Zora AI to clients. Deloitte has published no business return for any named internal use case and no firm-level return on AI; the only quantified internal goal is a Mar 2025 target to cut expense-management costs 25% with Zora AI, with no outcome reported.

Adoption

Deloitte spread generative AI member firm by member firm: DARTbot for nearly 18,000 U.S. audit professionals in Oct 2023, PairD for 75,000 people in Europe and the Middle East from Dec 2023, MyAssist for Deloitte Australia's 13,000 people in Jun 2024 and eBuddy for more than 30,000 users in five European member firms (2025), then Claude across the network of more than 470,000 people in Oct 2025 and Gemini Enterprise for more than 25,000 by Apr 2026. Deloitte mostly reports access and training, not active use: its audit professionals ran more than three million prompts in the first year of Deloitte's employee-wide generative AI chatbot (Jul 2025), and Deloitte said in Aug 2026 that it was upskilling more than 300,000 people through the Deloitte AI Academy.
