Episode 4: How Chinese Open-Source Models Are Rewriting AI Economics｜5Y Capital’s Meng Xing

About this Episode

Silicon Valley 101 premieres on YouTube on August 18, 2026.

China’s AI ecosystem is moving fast. Kimi, DeepSeek, and Z.ai are building increasingly capable AI models. But how much is Silicon Valley actually paying attention?
Xing Meng, partner at 5Y Capital, joins us for an inside look at China’s AI industry and the rise of Chinese open-source and open-weight models. We discuss Kimi and Moonshot AI, DeepSeek, ByteDance, the young researchers behind China’s frontier AI labs, and how China’s AI ecosystem differs from the US.
We also dig into the distillation debate, video models, data providers, and why Chinese models may be having a bigger impact on AI developers than on researchers at OpenAI, Anthropic and other frontier labs.
