Part 7/12:
A recurring theme in these breakthroughs is the central role of reinforcement learning. Both the independent researchers’ models and XAI's GrokFast employ RL techniques—particularly agent-based frameworks—to improve reasoning, reduce computation costs, and enhance scalability.
Elon Musk’s team appears to be leveraging an agent infrastructure optimized for training large models efficiently. The synergy between RL and model scaling suggests that the future of AGI might be embedded in reinforcement learning frameworks, rather than solely relying on transformer architectures.
