What happens if China pulls the plug on open-source AI? | Ep 21

Today’s show:
China is weighing a ban on foreign access to its top AI models… the same low-cost open-weight systems on which half of the Valley’s startups are building. So we asked our two all-star panelists — Arena CEO/Co-Founder Anastasios Angelopoulos and Hippocratic AI CEO/Co-Founder Munjal Shah — what happens to US companies when their favorite cheap, powerful models vaporize overnight.
PLUS why Hippocratic runs 31 models in parallel to ensure clinical-grade safety, the latency-vs-intelligence tradeoff no one is optimizing for, and why a company’s benchmarks might become their most valuable IP.
