Ludwig Siegele, senior editor AI Initiatives at The Economist talks about how Chinese AI companies like DeepSeek and Alibaba are disrupting the status quo. They are building high-performing models at lower costs and releasing some of them as open source. How did they manage to pull this off and what does this mean for the global AI race? Ludwig joined The Economist as a US technology correspondent in 1998 and has covered the Silicon Valley since the Internet, as we know it, was born.
