Vyoma.AI, an L&T subsidiary, has announced a contract to build the largest artificial intelligence infrastructure in India—an Nvidia B300 factory—for the American startup Together AI. The value of this order is estimated at 10,000–15,000 crore rupees.
This factory will be located on the Vyoma data center campus in Chennai and is intended to provide an AI-focused cloud platform that will be used for large-scale training, fine-tuning, and inference tasks.
The Chennai data center possesses gigawatt-scale AI infrastructure. The first phase of the project is designed with a capacity of 250 MW, and the energy infrastructure readiness stands at 150 MVA, providing a scalable foundation for future expansion of the AI factory. The factory has a capacity of 10,000 Nvidia B300 GPUs.
The platform provided by Vyoma integrates hyper-scale data center infrastructure, accelerated computing, high-performance networks, ultra-low latency interconnects, high-throughput parallel storage, and AI infrastructure operational capabilities.
S. N. Subramanian, Chairman and Managing Director of L&T, noted that deploying the Nvidia B300 factory for Together AI is a significant step in L&T's mission to create gigawatt-scale AI infrastructure, as artificial intelligence is becoming the foundation for all industries.
Earlier this week, L&T signed an agreement to transfer its data center and cloud services business to Vyoma.AI Ltd for a sum of 1,400 crore rupees.
Together AI actively pursues such partnerships. The company also signed a multi-year contract worth $240 million with IBM to build a large-scale AI cluster on IBM Cloud using Nvidia systems. The company's platform allows enterprises to train and run AI tasks on open models such as DeepSeek, MiniMax, and Kimi at lower costs compared to closed systems.
The San Francisco-based company was valued at approximately $8.3 billion in July, and Nvidia is among its clients. Co-founder and CEO Vipul Ved Prakash stated that 'making AI globally accessible will be the biggest construction project in human history, and L&T understands this.'
