How they deploy

Deployment model

Siemens runs AI through central teams and inside its businesses. A Data & Artificial Intelligence unit, led since Jul 1, 2025 by Executive Vice President Vasi Philomin and part of Managing Board member Peter Koerte's portfolio since Oct 1, 2025, drives industrial AI products such as the Eigen Engineering Agent; Siemens' global IT data and AI technology team runs SiemensGPT for employees together with the cybersecurity team; Digital Industries, Smart Infrastructure and Mobility build AI into their own products; and Global Business Services applies AI to HR, finance and procurement processes. Siemens uses its own factories, above all the Electronics Factory in Erlangen, as the first site for AI it later sells to customers.

Model providers

Siemens built SiemensGPT to avoid dependence on any one model provider: implementation partner FNTIO says the aim was to give every employee models such as Claude, GPT and Gemini, lists Anthropic, OpenAI and Meta's Llama in the platform's stack and counts about 50 models available (Mar 2026). Siemens software developers use AI coding assistants including GitHub Copilot (Jul 2025), and Siemens CIO Hanna Hennig listed Microsoft 365 Copilot among the company's everyday AI tools in office IT (Feb 2025). In its products, Siemens built the Industrial Copilot with Microsoft on Azure OpenAI Service (Oct 2023), is integrating NVIDIA NIM and Nemotron models into its chip design software (Jan 2026), and is exploring Alibaba's Qwen models for its product lifecycle management software in China (Mar 2026).

Data and infrastructure

Siemens runs SiemensGPT on AWS and built the Siemens Data Cloud, which FNTIO describes as a platform spanning 1,500 AWS accounts for the whole Siemens AI landscape; SiemensGPT users authenticate through Siemens' central identity provider and Amazon Verified Permissions makes every authorization decision, more than 590 million a month (AWS case study). Siemens' Industrial Copilot runs on Microsoft's Azure OpenAI Service (Oct 2023), its inbound sales agents run on Salesforce's Agentforce platform (Sep 2026), Siemens plans to validate cloud simulation services on Alibaba Cloud for customers in China (Mar 2026), and the AI applications Siemens and NVIDIA built at Erlangen use NVIDIA Cosmos world models, the NVIDIA Factory Operations Blueprint and Omniverse libraries (Oct 2026). Siemens says its technology generates more than 1 trillion data points a day, and has not said whether any of its internal AI runs in its own data centers.

Managing Board ownership of Data & AI with a central unit; IT runs the employee platform; businesses build AI into products

Siemens hired Vasi Philomin from Amazon as Executive Vice President and Head of Data & Artificial Intelligence on Jul 1, 2025, reporting directly to Peter Koerte, and placed Data & Artificial Intelligence in Koerte's Managing Board portfolio on Oct 1, 2025. Koerte's biography dated Oct 1, 2026 shows his Chief Technology Officer and Chief Strategy Officer titles ending in Sep 2026 and lists Data and AI, Strategy, Siemens Advanta and Siemens Xcelerator among his responsibilities alongside Smart Infrastructure, which he took over in Jul 2026. Cedrik Neike holds Managing Board responsibility for IT and cybersecurity, where Chief Information Officer Hanna Hennig (in the role since 2020, last confirmed in 2025) leads the IT organization whose global IT data and AI technology team runs SiemensGPT, and, according to his current biography, for Foundational Technologies; the Managing Board shrank from seven to five members in 2026.

Siemens counts more than 1,500 AI experts (Nov 2025 and Apr 2026) and more than 2,000 AI patent families, within 53,200 R&D employees on average in fiscal 2025; Fortune reported in Jul 2025 that Siemens already had more than 1,500 AI experts before late 2022 and about 27,000 software developers. Siemens committed hundreds of industrial AI experts to its expanded NVIDIA partnership in Jan 2026. Peter Koerte said in Mar 2026 that about 300 of the roughly 1,500 AI specialists are researchers and about 1,200 are engineers embedded in product teams, and that a new AI team in Seattle is expected to grow to 200 to 300 people. Siemens has not published how its AI specialists divide between the Data & AI unit, the businesses and Siemens Healthineers.

Use cases

Siemens had 460 AI use cases in production in Jul 2025, according to Fortune, not including more than 15,000 bots employees had built in SiemensGPT, and runs AI in its own factories, shared services, sales, communications and software development as well as in products such as the Industrial Copilot and the Eigen Engineering Agent. Siemens has not published a business return credited to AI for any internal use case: the factory gains it reports for Nanjing and Erlangen come from broader digital programs or are stated as potential, and the efficiency figures for its AI products are customer results. Peter Koerte said in Jul 2025 that the open question is how much Siemens has saved, and that Siemens hopes AI will double its 3% to 4% annual productivity target.

Adoption

Siemens spread AI in layers: applied AI in products and factories, which Siemens says goes back more than 50 years, an employee generative AI platform, SiemensGPT, in use by Oct 2024, coding assistants for its software developers, and agents in shared services and sales in 2025 and 2026. SiemensGPT had 120,000 users according to implementation partner FNTIO (Mar 2026) and 150,000 registered users, 80,000 of them active each month, according to an AWS case study updated in Oct 2026. Siemens Global Business Services is rolling out a four-week AI program for more than 1,000 leaders and a six-week course for more than 10,000 employees, which it also offers to other Siemens units. Peter Koerte said in Mar 2026 that Siemens teams were testing task-specific agents on an internal platform he called an AI factory, and Siemens built AI into all of its vocational training in Sep 2026.

Quick answers

How does Siemens deploy AI?

Siemens deploys AI on two tracks: SiemensGPT, an employee platform built on AWS with models from several providers, and industrial AI products such as the Industrial Copilot and the Eigen Engineering Agent, tested first in its own factories. An AWS case study counted 80,000 monthly SiemensGPT users in Oct 2026, a figure Siemens has not published itself. Managing Board member Peter Koerte owns Data and AI, and Siemens committed more than €1 billion over three years to AI offerings but has reported no business return it credits to AI.

What does Siemens use AI for?

Siemens had 460 AI use cases in production in Jul 2025, according to Fortune, not including more than 15,000 bots employees had built in SiemensGPT, and runs AI in its own factories, shared services, sales, communications and software development as well as in products such as the Industrial Copilot and the Eigen Engineering Agent. Siemens has not published a business return credited to AI for any internal use case: the factory gains it reports for Nanjing and Erlangen come from broader digital programs or are stated as potential, and the efficiency figures for its AI products are customer results. Peter Koerte said in Jul 2025 that the open question is how much Siemens has saved, and that Siemens hopes AI will double its 3% to 4% annual productivity target.

Who leads AI at Siemens?

AI at Siemens is led by Peter Koerte (Managing Board member responsible for Data and AI, Strategy, Siemens Advanta and Siemens Xcelerator; President Smart Infrastructure); Vasi Philomin (Executive Vice President and Head of Data and AI); Hanna Hennig (Chief Information Officer). Ownership of AI on the org chart: Peter Koerte, Managing Board member for Data & AI; EVP Vasi Philomin heads the Data & AI unit.

What AI platform does Siemens use?

SiemensGPT, an internal platform Siemens built on AWS with implementation partner FNTIO, gives employees vendor-agnostic access to large language models and a no-code builder for bots and agents (AWS case study, Oct 2026).

Which AI models does Siemens use?

SiemensGPT offers models from Anthropic, OpenAI and Meta among about 50 (FNTIO, Mar 2026); Siemens built its Industrial Copilot on Microsoft's Azure OpenAI Service (Oct 2023) and said in Jan 2026 it will add NVIDIA Nemotron models to its chip design software.

How many Siemens employees use AI?

SiemensGPT had 150,000 registered users, 80,000 of them active each month (AWS, Oct 2026), against about 317,000 Siemens employees, Siemens Healthineers included (Jun 2026).

How far has AI spread at Siemens?

Siemens has reported no business return it credits to AI: Peter Koerte told Fortune in Jul 2025 that how much Siemens has saved is still the open question, said in Mar 2026 that AI is so embedded in Siemens products that AI revenue is hard to isolate, and the factory gains Siemens reports for Nanjing and Erlangen come from broader digital programs or are stated as potential. Siemens has not itself reported a company-wide AI rollout with a count of employees using its tools: the 150,000 registered and 80,000 monthly SiemensGPT users come from an AWS case study updated in Oct 2026 and the 120,000 users from implementation partner FNTIO, while Koerte's own figure, about 27,000 software developers using AI coding assistants (Jul 2025), covers one function. That leaves Siemens at Experimenting although Koerte owns Data and AI on the Managing Board and AI runs in production in its factories, shared services and sales; one cost, revenue or headcount return Siemens credits to AI, or a SiemensGPT user count Siemens publishes itself, would move it to Piloting.

Open questions

• How many Siemens employees use SiemensGPT each week by Siemens' own count, given that the 150,000 registered users (AWS) and 120,000 users (FNTIO) come from partner case studies, and how do they compare with the Siemens workforce outside Siemens Healthineers?
• What financial return has Siemens measured from internal AI, given that Peter Koerte called the amount saved the open question in Jul 2025?
• Is Siemens on track to double its 3% to 4% annual productivity target with AI, and how does it measure AI's share of that gain?
• What business return do Siemens' deployed internal tools deliver, such as SiemensGPT, the coding assistants, ServicePilot, cash collection AI and the Agentforce lead process?
• How much of the €1 billion AI investment goes to internal tools rather than products, and what do SiemensGPT and its model usage cost?
• Which models carry most SiemensGPT traffic, does any internal AI besides Microsoft 365 Copilot run on Microsoft Azure or in Siemens' own data centers, and is any model fine-tuned on Siemens data?
• Who holds Siemens' Chief Technology Officer title after Peter Koerte's ended in Sep 2026, is Hanna Hennig still Chief Information Officer, and does the Data & AI unit still report through Koerte now that he also runs Smart Infrastructure?
• How many AI use cases does Siemens run in production today, given that the most recent public figure, 460, dates from Jul 2025?
• What returns do Siemens' own factories credit to AI alone, as opposed to the broader digital programs behind the Nanjing and Erlangen results?
• Does Siemens use the Eigen Engineering Agent and Industrial Copilot in its own automation engineering, and with what result?
