L&T NVIDIA B300 AI Factory: Amazing 10,000-GPU Deal Worth Rs. 15,000 Crore
The L&T NVIDIA B300 AI Factory has just been confirmed as India’s largest single-cluster AI infrastructure facility, after Larsen & Toubro secured a mega order worth Rs. 10,000-15,000 crore. Here’s a complete breakdown of the deal, who it’s being built for, and how it fits into L&T’s much bigger AI infrastructure push with NVIDIA.
What Is the L&T NVIDIA B300 AI Factory?
The L&T NVIDIA B300 AI Factory is a 10,000-GPU cluster being built by LTN Compute, L&T’s AI infrastructure arm, at the Chennai data centre campus of Vyoma.AI, L&T’s dedicated AI and data centre business. Once complete, it will stand as India’s largest single-cluster artificial intelligence infrastructure facility, built entirely around NVIDIA’s latest B300 GPUs.
Who Is the L&T NVIDIA B300 AI Factory Being Built For?
The facility is being built for Together AI, a San Francisco-based company founded in 2022 by Chris Ré, Vipul Ved Prakash, Tri Dao, and Percy Liang. Together AI runs an “AI Native Cloud” platform used for training, fine-tuning, and deploying generative AI models, hosting over 200 open-source models across chat, image, audio, vision, and code. The company has raised $1.33 billion in funding, is valued at around $3.3 billion, and already counts Zoom and Salesforce among its customers.
Together AI co-founder Vipul Ved Prakash said of the partnership: “L&T brings the scale, reliability and engineering capability required.”
Deal Size and Capacity
- Order value: Rs. 10,000 to 15,000 crore
- GPU count: 10,000 NVIDIA B300 GPUs
- First phase capacity: 250 megawatts
- Power infrastructure: Designed to support 150 MVA, with room for future expansion
- Purpose: Large-scale AI training, fine-tuning, and inference workloads
Part of a Much Bigger L&T-NVIDIA Push
This isn’t L&T’s first move with NVIDIA. Back in February 2026, the two companies announced plans to build India’s largest gigawatt-scale AI factory under the government’s IndiaAI Mission, scaling L&T’s Chennai data centre to 30 MW capacity across a 300-acre gigawatt-scalable campus, alongside a separate new 40 MW data centre under execution in Mumbai.
At the time, L&T Chairman and Managing Director S N Subrahmanyan said: “India’s enterprises are ready to move from AI pilots to production-scale deployment. The investment establishes the foundation, secure, scalable, and sovereign infrastructure, required to power manufacturing, energy, financial services, healthcare and public services.” NVIDIA founder and CEO Jensen Huang added: “AI is driving the largest infrastructure buildout in human history, everyone will use it, every company will be powered by it and every country will build it.”
Why This Matters for India’s AI Ambitions
The IndiaAI Mission is built around the idea of sovereign AI infrastructure, letting India’s critical data, models, and AI workloads be built, trained, and deployed domestically while still staying interoperable with global AI ecosystems. A facility the scale of the L&T NVIDIA B300 AI Factory is exactly the kind of large-scale compute capacity that mission depends on, and landing a marquee international client like Together AI signals that India’s AI infrastructure is now credible enough to serve global demand, not just domestic needs.

India’s technology ecosystem has been moving fast on multiple fronts this year, not just AI compute, our coverage of the Android Canary 2608 update looks at another significant tech development shaping the country’s digital landscape.
Government-Backed Capital Is Flowing Into Strategic Sectors
Large, government-aligned infrastructure investment isn’t limited to AI compute either, our coverage of the Ola Electric PLI Scheme Window tracks a similar government-linked capital push, this time in battery manufacturing rather than AI data centres.
What Happens Next
With the first phase of the L&T NVIDIA B300 AI Factory targeted at 250 MW and built for future expansion, this facility is likely to be one of several similar announcements as more global AI companies look to India for compute capacity. For now, it stands as one of the clearest signals yet that India intends to be a serious player in global AI infrastructure, not just AI software and services.
