Tokyo – April 25 2025 – NTT DATA, a global leader in digital business and technology services, today announced enhancements to user-enabled generative AI (GenAI) capabilities through a strategic business collaboration with Weights & Biases. Giving developers the ability to fine-tune large language models (LLMs) with Weights & Biases‘ tools on NTT DATA‘s Generative AI Technology Hub (NTT DATA GenAI Tech Hub) solutioning platform allows NTT DATA and its clients to create models that are more optimized to requirements and drive greater business impact.

NTT DATA GenAI Tech Hub is a global repository of reusable GenAI building blocks, designed to accelerate development tasks and deployment of GenAI applications at scale. NTT DATA GenAI Tech Hub delivers higher efficiency with ready-to-use assets and modular components, empowering enterprises with AI-driven solutions faster and more cost-effectively. With centralized access to tools and accelerators, NTT DATA GenAI Tech Hub allows teams to focus on value creation, reducing time-to-market and development costs while ensuring streamlined governance and compliance. By collaborating with Weights & Biases, NTT DATA has enhanced capabilities even further, allowing more domain-specific data models.

NTT DATA has placed GenAI at the core of its innovation strategy, focusing on fine-tuning LLMs and Small Language Models (SLMs) to meet specific business requirements. By customizing pre-trained AI models, NTT DATA delivers tailored solutions that effectively address real-world client challenges with efficiency and precision. Furthermore, with this new capacity for creating highly focused LLMs and SLMs, NTT DATA will enhance Smart AI Agents Platform/Agentic AI solution, achieving high performance, accuracy, and quality at a lower cost.

NTT DATA conducted a comprehensive Proof of Value assessment to evaluate the effectiveness of Weights & Biases‘ tools in improving training traceability and results analysis. The assessment utilized W&B Models and W&B Weave, demonstrating optimized development workflows and insights. Key findings highlighted seamless integration with third-party libraries and ease of tool incorporation into existing components for LLM evaluation, streamlining workflows and boosting efficiency.

The Weights & Biases tool integration into NTT DATA GenAI Tech Hub will help heighten synergistic effects and enterprise innovation. AI teams are empowered to overcome complex development challenges while delivering transformative, high-impact solutions. Combining NTT DATA‘s AI expertise and GenAI Tech Hub platform with the robust tools and infrastructure of Weights & Biases represents a game-changing approach to scaling AI advancement and to addressing evolving client needs.

“The enhanced NTT DATA GenAI Tech Hub, powered by our collaboration with Weights & Biases, enables advanced fine-tuning of LLMs and SLMs to meet specific business needs. This will significantly boost our Agentic AI solution, delivering higher performance and accuracy, and accelerate our customers’ transformation to AI-driven business models,” said Kenji Motohashi and Carlos Galve Pellicero, Co-Heads of the Global Generative AI Office, NTT DATA.

Lukas Biewald, CEO, Weights & Biases – “Adoption of W&B at NTT DATA marks an exciting milestone in our mission to empower AI engineers creating the next generation of AI applications. This collaboration will allow NTT DATA‘s global teams to focus on solving their customers’ problems, fine-tuning models faster into their domains with greater precision, and building AI applications with observability.”
