L&T's Vyoma.AI to Host Nvidia B300 'AI Factory' for Together AI in Chennai, Claimed India's Largest Single-Cluster AI Infrastructure

Indian construction and engineering conglomerate Larsen & Toubro (L&T) has entered a significant partnership to host high-performance GPU capacity for US-based AI startup Together AI, marking one of the largest artificial intelligence infrastructure deployments in India to date. The agreement, announced this week through L&T's AI infrastructure subsidiary LTN Compute, will see the company's Vyoma.AI unit host an Nvidia B300 'AI Factory' for the AI acceleration cloud provider.

The companies said the deployment will constitute India's largest single-cluster AI infrastructure, with the hardware comprising 10,000 Nvidia B300 GPUs. The hardware will be hosted at Vyoma's Chennai data center campus, where the first phase of development will deliver 250MW of capacity. According to reports, the value of the deal is estimated at approximately $1 billion to $1.75 billion.

Artificial intelligence has become foundational to industrial and enterprise growth across sectors, and dedicated AI factories are emerging as critical infrastructure for training and deploying large-scale models. This deployment is part of L&T's broader Gigawatt AI Infrastructure Mission, which aims to position India as a global hub for next-generation AI compute. "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 of Larsen & Toubro.

Together AI, founded in 2022, operates as an AI acceleration cloud provider that leases GPUs from other cloud providers and re-leases them to developers, while also purchasing its own servers to rent from its data centers. The company has been expanding its capacity footprint through multiple partnerships, including recent agreements with IBM Cloud and Rumble Inc. "Making AI globally accessible is going to be the biggest infrastructure build-out in human history, and L&T understands that," said Vipul Ved Prakash, co-founder and CEO of Together AI. "That's exactly why we partnered with them – to bring the scale, resilience and engineering excellence this moment demands to India."

Vyoma, L&T's AI cloud and hyperscale data center business, offers sovereign cloud platforms, GPU-as-a-Service, and hyperscale colocation. L&T rebranded its Cloudfiniti data center business to Vyoma last year and added a cloud platform to the offering in February. The subsidiary is targeting the construction of over 200MW of capacity across India. It currently operates two live data centers – a 2MW facility in Navi Mumbai and a 30MW facility in Chennai – with two additional facilities in development, according to its 2025 annual review.

The partnership underscores the rapid growth of AI infrastructure demand in India, driven by both domestic enterprises and global AI companies seeking compute capacity outside traditional markets. Together AI has also recently announced plans to deliver a dedicated cluster for Y Combinator, giving the accelerator's portfolio of AI-native startups access to the compute they need to build and scale. The Chennai deployment with L&T marks a strategic expansion for Together AI, which has previously signed deals with Hypertec and 5C for capacity in Europe and uses Hypertec Cloud for additional capacity. As AI workloads continue to scale globally, the availability of large-scale, single-cluster GPU infrastructure in emerging markets is expected to play a pivotal role in democratizing access to advanced computing resources.
