What happened this week in AI by Louie This week in AI, we were particularly interested in seeing two new agent models released. Nvidia has unveiled Eureka, an AI agent designed to guide robots in executing complex tasks autonomously. This agent, powered by GPT-4, can independently generate reward functions that surpass the performance of human experts in 83% of tasks, achieving an average enhancement of 52%. The fascinating demo shared by the company illustrates the agent’s ability to train a robotic hand to perform the rapid pen-spinning trick and a human. As mentioned by one of the authors in a blog post, this library utilizes generative AI and reinforcement learning to solve complex tasks.
