PufferLib update says Ocean has about 60 environments, nearly all with local browser baselines

A PufferLib announcement says about 60 Ocean environments are available on puffer.ai. Almost all have strong baselines that run locally in the browser—not on the team's servers—which it credits to the models' small size. A related update reports roughly fivefold faster training versus version 4.0, measured by average solve time on the same tasks. It credits async changes, kernel tweaks and algorithmic improvements, reporting 3× speedups “pretty much across the board” and 10× in some environments.
