OpenAI signed a partnership with Tata Group to take 100MW of AI-ready data center capacity in India as the first customer of TCS’s HyperVault business, with an agreed pathway to scale to 1GW, and to deploy ChatGPT Enterprise across Tata’s workforce.

This immediately adds contracted in-country compute capacity for OpenAI, reducing reliance on cross-border inference/training routes and improving latency and data-residency options for India-based enterprise customers. Making HyperVault’s first anchor tenant accelerates Tata’s ability to finance and fill its planned ₹180 billion (~$2B) buildout, tightening the window for rival cloud/data-center operators to secure the same power-and-land-constrained capacity. The ChatGPT Enterprise rollout and AI-native development standardization inside Tata creates a large reference deployment that can pull forward procurement cycles for OpenAI’s enterprise products in India.
