Here's my try:


DreamerV3 is a scalable reinforcement learning algorithm that can learn to master a wide range of domains with fixed hyperparameters. The authors systematically address varying signal magnitudes and instabilities in all of its components. DreamerV3 succeeds across 7 benchmarks and establishes a new state-of-the-art on continuous control from states and images, on BSuite, and on Crafter. Moreover, DreamerV3 learns successfully in 3D environments that require spatial and temporal reasoning, outperforming IMPALA in DMLab tasks using 130 times fewer interactions and being the first algorithm to obtain diamonds in Minecraft end-to-end from sparse rewards. Finally, they demonstrate that the final performance and data-efficiency of DreamerV3 improve monotonically as a function of model size.

Limitations include that DreamerV3 only learns to sometimes collect diamonds in Minecraft within 100M environment steps, rather than during every episode. Despite some procedurally generated worlds being more difficult than others, human experts can typically collect diamonds in all scenarios. Moreover, we increase the speed at which blocks break
