dreamer_v3_25m(pretrained: bool = False, overrides: object = {})Construct the second rung — no objectives, just the model.
A model dimension of 384. The ladder steps by roughly 1.5 each rung, alternating powers of two with powers of two times 1.5, which keeps every tensor width a multiple of eight.
