Fujitsu's Dual AI Deal: Claude for Defence & ChatGPT for Ops

Fujitsu has announced partnerships with both Anthropic and OpenAI. The Japanese technology equipment and services company will deploy different AI models for different operational requirements.
The approach could signal a shift away from single-vendor AI strategies. According to Fujitsu, the dual partnerships will allow the company to balance cyber defence and regulatory compliance against enterprise automation and industrial productivity.
Claude for critical infrastructure
Fujitsu will use Anthropic's Claude model family for domains where data sovereignty, regulatory compliance and security are required. These include government, finance, healthcare, defence and critical infrastructure.
Anthropic was founded in 2021 by Dario and Daniela Amodei alongside other senior researchers who left OpenAI. The departure was reportedly due to differences regarding AI safety, security and commercialisation speed.
Fujitsu will use Anthropic tools to enable human expertise and AI to work together for cyber defence responses. The company is collaborating with the Japanese government to scale these frameworks across society.
Approximately 100,000 Fujitsu Group employees will use Claude to validate safe, controllable AI usage. The system will be combined with Fujitsu's proprietary Takane LLM and Kozuchi AI platform.
According to Fujitsu, the company is advancing AI-driven development platforms and working on automating large-scale system upgrade processes using AI agents based on its proprietary Takane LLM. The company aims to enhance development productivity by combining these efforts with Claude.
Paul Smith, Chief Commercial Officer at Anthropic, says: "The institutions that anchor Japanese society – its banks, its hospitals, its government, its critical infrastructure – hold AI to the highest standard.
"Fujitsu has been the technology partner to those institutions for decades, and they are now deploying Claude to 100,000 of their own employees and building a 1,000-person engineering team to bring it to their customers. This is one of the most consequential commitments to frontier AI in the Japanese market and we're proud for Anthropic to be the partner Fujitsu trusts to deliver on that commitment."
OpenAI for enterprise automation
OpenAI will be positioned as the engine for broad enterprise growth, particularly within commercial markets like manufacturing, pharmaceuticals and system integration. Fujitsu will integrate ChatGPT Enterprise and Codex to establish a collaborative model where humans and AI agents work together across commercial development, sales operations and delivery.
Cybersecurity remains part of this implementation. However, the emphasis with OpenAI leans toward human creativity, supply chain optimisation and corporate decision-making.
Tadao Nagasaki, President of OpenAI Japan, says: "OpenAI aims to bring the benefits of AI broadly to society and help build a future in which people and businesses can create greater value.
"Achieving this requires partners that can implement advanced AI in real-world settings across Japanese industry and society, and expand its use in ways that earn trust.
"With deep expertise and execution capabilities in critical fields including manufacturing, healthcare and pharmaceuticals, and cybersecurity, Fujitsu is well positioned to play an important role in advancing AI adoption in Japan.
"Through this collaboration, OpenAI will support Fujitsu in advancing its transformation and work together to help businesses and society in Japan unlock new opportunities for growth and build a more prosperous future with AI as a catalyst."
Forward deployed engineer model
Both partnerships converge on a single operational strategy. Fujitsu's forward deployed engineer (FDE) model sends engineers directly onsite to work alongside clients.
By feeding both Claude's specialised reasoning and OpenAI's automation tools into this model, Fujitsu aims to shift clients toward business models that could result in efficiency gains.
The approach treats AI models as specialised components rather than off-the-shelf software. This could allow Fujitsu to tailor its offerings to the regulatory, performance and security requirements of its client base.
Takahito Tokita, Representative Director and CEO of Fujitsu, says: "We see the rapid evolution and growth of AI as something that must be swiftly implemented in society and translated into value creation – this is a top priority for us as a technology company.
"Through this collaboration, we will combine Fujitsu's deep expertise across industries and business functions – particularly its extensive know-how in mission-critical domains.
"In doing so, we aim to support the creation of new value across industries and realise a trustworthy, AI-driven society."
