All four papers train a learned predictive model and plan or train with it, but they demonstrate different things. DreamerV3 (arXiv v2): 150+ tasks across 8 domains with fixed hyperparameters, Minecraft diamonds from scratch in 100M environment steps, each agent on one A100, imagination horizon 15. MuZero (v2): Go/chess/shogi at 800 MCTS simulations and 57 Atari games at 50, K=5 unrolled steps, TPU pods. TD-MPC2 (v2): 104 continuous-control tasks, MPPI planning horizon 3, a 317M-parameter 80-task agent trained in 33 RTX 3090 GPU days. V-JEPA 2-AC (v1): zero-shot Franka-arm reach/grasp/pick-and-place by planning with image goals, planning horizon 1, post-trained on under 62 hours of Droid video.

Curator qualifications: DreamerV3 v2: Table 4 'Imagination horizon' value 15; body text 'rewards beyond the prediction horizon T = 16'; 'one A100' 1. MuZero v2: '800 simulations' 7, '50 simulations' 8, 'K = 5' 2. TD-MPC2 v2 Table 8: 'Planning Horizon (H) 3', MPPI 2; '317M' 10. Curator note: DreamerV3's body text speaks of a 'prediction horizon T = 16' while Table 4 lists imagination horizon 15; plausibly 15 imagined steps from a start state (16 states), but the paper does not reconcile them in the passages read. Cite Table 4 and note the T = 16 wording.
