This chapter covers the release of various open-source models like GR00T, GRAC 1, Grok-1, and discusses their architecture, features, and potential improvements, signaling a shift towards transparency in model sharing. It delves into the introduction of stable video 3D synthesis, the evolution of generative AI models, and Google's D-Paco paper proposing a distributed approach to training AI models. Additionally, it explores new directions in large-scale learning, Apple's insights on building AI models, and a memory-efficient reinforcement learning technique for chatbots.
