L&T bags mega ₹10,000-15,000 crore order to build India’s largest NVIDIA B300 AI factory

Larsen & Toubro (L&T) on Thursday said it has secured a mega order to build what it described as India’s largest single-cluster AI infrastructure, deploying 10,000 NVIDIA B300 GPUs at its Chennai data centre campus for US-based AI cloud company Together AI.

The order is classified to be in the range of Rs 10,000 crore to Rs 15,000 crore.

The project marks L&T’s entry into the AI Factory business as the company looks to expand its presence in AI infrastructure. The facility will support Together AI’s AI-native cloud platform, catering to large-scale AI training, inference and fine-tuning workloads.


The shares of Larsen Toubro were trading at Rs 4046.55 apiece on the BSE, up 1.37% on Thursday as of 11.40 AM.

The AI Factory will be developed by L&T’s AI infrastructure subsidiary LTN Compute, part of Vyoma.AI, and hosted at Vyoma’s Chennai data centre campus.

The Chennai campus is planned as a gigawatt-scale AI infrastructure site. Its first phase is designed for 250 MW, with power infrastructure readiness of 150 MVA, allowing the company to expand AI Factory capacity in the future.

The infrastructure will combine data centre capacity with accelerated computing, high-performance networking, ultra-low-latency interconnects, parallel storage and AI infrastructure operations.

The platform is designed to allow customers to deploy and scale AI workloads through a single infrastructure stack.

“Artificial Intelligence is becoming foundational to every industry and AI Factories will power this transformation. Our deployment of an NVIDIA B300 AI Factory for Together AI marks a significant milestone in L&T's Gigawatt AI Infrastructure Mission and reinforces our commitment to making India a global hub for next-generation AI infrastructure,” said S N Subrahmanyan, chairman and managing director, Larsen & Toubro.

Vipul Ved Prakash, co-founder and CEO of Together AI, said, “Making AI globally accessible is going to be the biggest infrastructure build-out in human history, and L&T understands that. That's exactly why we partnered with them— to bring the scale, resilience and engineering excellence this moment demands to India.”

LTN Compute is developing AI-ready digital infrastructure in India across hyperscale AI data centres, sovereign cloud platforms, AI Factory services, GPU-as-a-Service and managed AI platforms.

The company said these services will cater to governments, enterprises, cloud providers and AI companies as demand for computing infrastructure grows.
