Anthropic's US directive blocks Fable 5, Mythos 5 for India – sparks sovereign AI debate

Anthropic abruptly suspended access to its newest AI models, Fable 5 and Mythos 5, for all foreign nationals—including its own foreign national employees—after receiving a U.S. government directive. The move comes shortly after Anthropic announced a partnership with Indian IT giant Tata Consultancy Services to expand enterprise AI in India, highlighting how deeply the country's AI ambitions are tied to U.S.-governed technologies. While the White House is reportedly unlikely to extend similar restrictions to other AI firms and privately blames Anthropic's handling of alleged jailbreak vulnerabilities, the event has sent shockwaves through India's tech sector.

Indian founders and investors now openly question the wisdom of depending on a handful of U.S. frontier model providers. Aakrit Vaish of Activate said the decision "materially changes" how India should think about sovereign AI, and he plans to push portfolio companies toward open-source models. Vijay Rayapati of Atomicwork warned that startups with mixed-country teams face a competitive disadvantage if access to advanced AI becomes geopolitically restricted. The debate adds to existing concerns about AI reshaping global talent economics, as seen in Opendoor's recent closure of its India office. The episode may accelerate moves toward domestic AI infrastructure and policy in India.
