Core Insights - The article discusses the transition of AI from a phase focused on model innovation and benchmark testing to a new phase emphasizing problem definition and evaluation [3][23][30] - It highlights the importance of reinforcement learning achieving generalization capabilities, allowing it to tackle diverse tasks previously thought to be unrelated [3][4][21] Group 1: AI's First Half - The first half of AI's development was characterized by significant breakthroughs in training methods and models, such as Transformer and GPT-3, which focused on improving model performance on benchmarks [4][5][7] - The emphasis was on creating new models rather than defining tasks, leading to a cycle of developing increasingly difficult benchmarks that could be solved with existing methods [7][8][23] Group 2: Breakthrough Formula - The effective formula for AI's success includes large-scale language pre-training, scaling (data and compute), and the integration of reasoning and action [9][14] - The realization that prior knowledge is crucial for generalization has shifted the focus from solely algorithm development to understanding the environment and prior knowledge [15][21] Group 3: Transition to the Second Half - The second half of AI will focus on redefining evaluation frameworks and creating new assessment methods that reflect real-world applications rather than just benchmark performance [26][27][29] - The industry faces the "utility problem," where existing evaluation frameworks do not align with real-world tasks, necessitating a reevaluation of how AI's effectiveness is measured [27][29] Group 4: Future Directions - The new game in AI's second half involves leveraging existing formulas to solve real-world tasks while innovating new components to enhance these formulas [32] - Companies will need to create new hypotheses that challenge existing paradigms to achieve significant breakthroughs and develop valuable products worth billions or trillions [30][32]
