India's AI Infrastructure Boom
L&T Enters AI Factory Business, Building India's Largest NVIDIA B300 Infrastructure
Key Points
S. N. Subrahmanyan described the NVIDIA B300 AI Factory deployment as a milestone in L&T's Gigawatt AI Infrastructure Mission and a step toward making India a global hub for next-generation AI infrastructure.
Vipul Ved Prakash, co-founder & 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," highlighting the ambition behind the partnership.
LTN Compute’s offerings go beyond the AI factory and data centre build to include GPU-as-a-Service (GPUaaS) and sovereign cloud platforms, as part of a broader portfolio of AI-enabled infrastructure services.
Together AI’s leadership emphasized that the collaboration with L&T brings scale, resilience and engineering capabilities required for the next phase of India’s AI infrastructure development.
Larsen & Toubro has landed a deal worth up to $1.6 billion — roughly Rs 15,000 crore — to build India's largest single-cluster AI infrastructure, according to MarketWatch and Economic Times. The project will deploy 10,000 NVIDIA B300 GPUs at a Chennai data centre campus run by Vyoma.AI.
The client is Together AI, a US-based cloud company focused on large-scale AI training and inference. L&T's win marks the company's formal entry into the AI Factory business — a segment that puts India on the map as a serious player in global AI infrastructure.
India's Largest AI Cluster Takes Shape in Chennai
Vyoma.AI's Chennai campus is designed to grow to gigawatt scale. Phase 1 targets 250 MW of capacity, with 150 MVA of power infrastructure already in place for future expansion, according to Economic Times. The site combines accelerated computing, low-latency networking, and high-throughput storage on a single unified stack.
The 10,000 NVIDIA B300 GPUs will power Together AI's cloud platform. Customers will be able to train, run, and fine-tune large AI models on the same infrastructure. That kind of all-in-one setup is what the industry calls an "AI Factory" — a factory that produces AI instead of physical goods.
Together AI CEO: This Is the Biggest Build-Out in Human History
Together AI co-founder and CEO Vipul Ved Prakash made clear how large the ambition is. "Making AI globally accessible is going to be the biggest infrastructure build-out in human history," he said, "and L&T understands that." The comment signals that this Chennai project is just the beginning of a much bigger push.
L&T chairman S. N. Subrahmanyan called the NVIDIA B300 deployment a milestone in L&T's "Gigawatt AI Infrastructure Mission." He framed it as a step toward making India a global hub for next-generation AI infrastructure — not just a place where foreign tech is consumed, but where it is built and operated at scale.
L&T's AI Arm Goes Beyond Bricks and Servers
L&T is not just building the physical facility. Its AI infrastructure arm, LTN Compute, will also offer GPU-as-a-Service — meaning companies can rent raw computing power by the hour or job. LTN Compute also plans to run a sovereign cloud platform, giving Indian organizations a local, secure option for sensitive AI workloads.
Together AI's leadership said the partnership brings "scale, resilience and engineering capabilities" needed for India's next phase of AI growth. For L&T, a company long known for building bridges, airports, and power plants, the deal is a sharp pivot into digital infrastructure — one of the fastest-growing sectors in the world.
A $1.6 Billion Bet on India's AI Future
The order value — between Rs 10,000 crore and Rs 15,000 crore — puts this among the largest single AI infrastructure contracts ever awarded in India. MarketWatch and regional editions of MarketScreener all pegged the top-end value at $1.6 billion, underlining the deal's global significance.
India's engineering sector has been watching AI infrastructure as a growth driver for years. This deal shows that ambition is now converting into real contracts. With 10,000 of NVIDIA's newest B300 chips going into a single site, Chennai is about to host one of the most powerful AI clusters anywhere in Asia.
