Sam Altman warns AI monopolies bad

OpenAI CEO Sam Altman warned AI monopolies are 'very bad'.

Microsoft CEO Satya Nadella said trust, open ecosystems, and US AI leadership will help beat Chinese AI competition.

Nadella noted Chinese AI models run on American cloud infrastructure and are open-weight, allowing US oversight.

Microsoft owns about 27% of OpenAI's for-profit public benefit corporation.

Chinese AI models like DeepSeek and Moonshot AI's Kimi K3 are challenging US AI with lower costs.
