As basic AI models become replaceable, value shifts to enterprise adaptation. Indian IT firms possess a unique, hard-to-replicate advantage: existing access and trusted relationships within global enterprises. This allows them to build customized “private AI layers,” integrating securely with proprietary data and applications, rather than focusing on foundational models. India's opportunity lies in vertical AI, leveraging domestic infrastructure, domain knowledge, and incumbency for reliable deployment. While competition exists, Indian firms can win by turning access into demonstrable reliability, deep integration, and accountability, thereby owning the valuable applied AI layer for global clients.
