喝点VC｜红杉美国对谈OpenAI前研究主管：预训练已经进入边际效益递减阶段，其真正杠杆在于架构的改进

Core Insights - The article discusses the evolution of AI, particularly focusing on the "trinity" of pre-training, post-training, and reasoning, and how these components are essential for achieving Artificial General Intelligence (AGI) [3][4][5] - Bob McGrew emphasizes that reasoning will be a significant focus in 2025, with many opportunities for optimization in compute usage, data utilization, and algorithm efficiency [4][5][6] - The article highlights the diminishing returns of pre-training, suggesting that while it remains important, its role is shifting towards architectural improvements rather than sheer computational power [6][8][9] Pre-training, Post-training, and Reasoning - Pre-training has reached a stage of diminishing returns, requiring exponentially more compute for marginal gains in intelligence [7][8] - Post-training focuses on enhancing the model's personality and intelligence, which can yield broad applicability across various fields [9][10] - Reasoning is seen as the "missing piece" that allows models to perform complex tasks through step-by-step thinking, which was previously lacking in models like GPT-3 [14][15] Agent Economics - The cost of AI agents is expected to approach the opportunity cost of compute usage, making it challenging for startups to maintain high pricing due to increased competition [17][18][19] - The article suggests that while AI can automate simple tasks, complex services requiring human understanding will retain their value and scarcity [19][20] Market Opportunities in Robotics - There is a growing interest in robotics, with the belief that the field is nearing commercialization due to advancements in language interfaces and visual encoding [22][25] - Companies like Skilled and Physical Intelligence are highlighted as potential leaders in the robotics space, capitalizing on existing technology and research [22][25] Proprietary Data and Its Value - Proprietary data is becoming less valuable compared to the capabilities of advanced AI models, which can replicate insights without extensive human labor [29][30] - The article discusses the importance of specific customer data that can enhance decision-making, emphasizing the need for trust in data usage [31] Programming and AI Integration - The integration of AI in programming is evolving, with a hybrid model where users engage in traditional coding while AI assists in the background [32][33] - The article notes that while AI can handle repetitive tasks, complex programming still requires human oversight and understanding [33][34] Future of AI and Human Interaction - The article explores how different generations interact with AI, suggesting that AI should empower individuals to become experts in their interests while alleviating mundane tasks [39][42] - It emphasizes the importance of fostering curiosity and problem-solving skills in the next generation, rather than merely teaching specific skills that may soon be automated [43][44]
