AI Development Paradigm Shift: From Chasing Benchmarks to Creating Value: OpenAI researcher Yao Shunyu’s blog post sparked discussion, proposing that AI development has entered its second half. The first half focused on algorithmic innovation and benchmark chasing (e.g., AlphaGo, GPT-4), achieving generalization breakthroughs by combining large-scale pre-training (providing prior knowledge) with reinforcement learning (RL) and introducing the concept of “reasoning as action”. However, he argues that the marginal benefits of continuously chasing benchmarks are diminishing. The second half should shift towards defining problems with practical application value, developing evaluation methods closer to the real world, thinking like a product manager, and truly using AI to create user and social value, rather than just pursuing metric improvements. This marks a mindset shift in the AI field from primarily technology exploration to application implementation and value realization (Source: dotey)
