RL Infrastructure - developing and maintaining cutting-edge, reliable and distributed RL infrastructure, while pushing the edge of what is possible in distributed RL training. RL Integrations - enhancing the global quality of the post-training codebase by implementing new tools to ease and support research, optimizing post-training algorithms, and scaling distributed RL to unprecedented levels.
