EP 100. Claude Mythos, Fable 5, 그리고 다음 국면은?

AI Frontier reaches its 100th episode. What began three years ago with GPT-4 and "Sparks of AGI" has now become a conversation about Claude Mythos, Fable 5, RSI, loop engineering, sovereign AI, and independent foundation models. In this episode, we discuss what Anthropic's Fable 5 and Mythos-class model reveal about the next stage of frontier AI. The competition is no longer just about benchmark performance. It increasingly revolves around safety layers, post-training, dataset engineering, test-time compute, pricing, and AI as a strategic asset. We also talk about the current mood in Silicon Valley, how young frontier startups interact with capital, how AI is spreading into biology and drug discovery, and what opportunities Korea may have in the foundation model era. Finally, we reflect on what AI Frontier should become after episode 100, including new sessions around Palantir FDEs and the changing nature of engineering in the agent era.
