Enter Agent Q, a major milestone for Agents combining search, self-critique, and reinforcement learning to create state-of-the-art autonomous web agents that can plan and self-heal.

Has anyone implemented MCTS or https://arxiv.org/abs/2406.07394 for planning in real products beyond papers? would love some suggestions on this, since I am considering this route.
