Sam Altman's DevDay 2025 keynote introduces major platform updates, including the Apps SDK for building inside ChatGPT, AgentKit for streamlined agent creation, the general availability of the powerful Codex coding agent, and new API access to GPT-5 Pro and Sora 2.
Microsoft’s Eric Horvitz and guests discuss the Paraphrase Project, a two-year red-teaming effort that uncovered and patched a significant biosecurity vulnerability, demonstrating a model for responsibly managing the dual-use risks of generative AI in protein design.
A summary of the discussion with Dan Wang, author of "Breakneck", comparing the US and China through the lens of engineering versus legal mindsets. The conversation explores differences in infrastructure, industrial policy, manufacturing scale, and foreign policy, arguing for a nuanced view of a long-term competition rather than a short-term race.
Albert Cheng, who has led growth at Duolingo, Grammarly, and Chess.com, shares his framework for finding and scaling growth opportunities. He discusses the explore-exploit model, the keys to consumer subscription success like retention and resurrected users, and how AI is accelerating the experimentation cycle.
A reflection on Richard Sutton's "Bitter Lesson," arguing that while his critique of LLMs' inefficiency and lack of continual learning is valid, imitation learning is a complementary and necessary precursor to true reinforcement learning, much like fossil fuels were to renewable energy.
Dr. Ilia Shumailov, former DeepMind AI Security Researcher, explains why traditional security fails for AI agents. He details the unique threat model of agents, the dangers of supply chain attacks and architectural backdoors, and proposes a system-level solution called CAML to enforce security policies by design, separating model reasoning from data execution.
