Anthropic's Top AI Scientist Andrej Karpathy Reportedly Unable to Access Advanced Models Due to Non-U.S. Citizenship
Anthropic reportedly restricts access to advanced AI models for non-U.S. citizens, affecting top scientist Andrej Karpathy.
The restriction stems from U.S. export control directives targeting cutting-edge models like Anthropic's Mythos 5 and Fable 5, raising industry discussions as Karpathy holds a green card.
In market mechanisms, AI talent and institutional buyers accelerate the assessment of geopolitical and regulatory risks, with funding shifting from restricted frontier labs to environments with more open talent policies or alternative platforms, benefiting compliant local teams while organizations reliant on international talent face pressure.

Andrej Karpathy joined Anthropic in May 2026 after leaving OpenAI and Tesla, leading the pre-training team and having a significant impact on the AI community through open-source education and autoregressive research, playing a key role within the talent-dense environment of Anthropic.
In terms of capital pathways, Anthropic is responding to U.S. government export control directives by activating internal access control systems, motivated by the need to comply with national security requirements while maintaining core R&D progress, continuing to attract top global talent but needing to adapt to citizenship verification, balancing innovation speed with compliance costs.
Similar cases include the historical impact of ITAR/EAR regulations on sensitive technology exports affecting talent in the semiconductor and defense sectors, as well as recent AI export restrictions impacting other labs. Anthropic is currently transitioning from open collaboration to strict nationality-based access for frontier AI models.
Essentially, this is a regulatory change: the U.S. is strengthening domestic control over advanced AI technology through export control mechanisms, forcing labs to restructure their talent acquisition and model access pathways, driving capital concentration towards core teams led by U.S. citizens and accelerating the redistribution of global AI talent flow.

Genius knows no borders, but cutting-edge models have nationalities; regulation first cuts the leverage.
The more open talent attraction is, the higher the technological barriers are built, and contradictions are the true engine of innovation.
A green card is not a passport; a policy change can drive productivity from the lab to the airport.
