AI leaders clash over open models and China

In late July 2026, top executives from OpenAI and Anthropic publicly disagreed about the future of AI development. OpenAI's Sam Altman said AI has surpassed human intelligence, while Anthropic's Dario Amodei warned about the risks of open-weight AI models, particularly concerning Chinese competitors. The debate follows a letter from both companies asking the US government to help regulate the pace of AI development.
