PlaNet learns a latent dynamics model from image observations and plans directly in latent space using model-predictive control (MPC). It introduced the RSSM architecture and demonstrated that model-based approaches could match model-free methods while being dramatically more sample efficient.
PlaNet is a latent space planning model developed by Google in 2019 for continuous control.

| Comparison | Matchup | Summary |
|---|---|---|
| DreamerV3 vs PlaNet | DreamerV3 vs PlaNet | DreamerV3 represents the evolution of PlaNet's core ideas. Both use the RSSM architecture, but DreamerV3 adds discrete representations, symlog predictions, and fixed hyperparameters to achieve state-of-the-art performance across diverse domains. |
| DreamerV2 vs PlaNet | DreamerV2 vs PlaNet | Both use the RSSM architecture for latent dynamics, but DreamerV2 introduced discrete representations that dramatically improved performance. PlaNet pioneered the approach; DreamerV2 perfected it for Atari-scale environments. |
| DreamerV3 vs TD-MPC2 | DreamerV3 vs TD-MPC2 | Two leading model-based RL agents with different philosophies: DreamerV3 uses imagination-based actor-critic learning, while TD-MPC2 combines temporal-difference learning with model-predictive control for multi-task mastery. |
| Ha & Schmidhuber World Model vs DreamerV3 | Ha & Schmidhuber World Model vs DreamerV3 | The original 2018 'World Models' paper vs. the current state-of-the-art: how five years of research transformed a foundational concept into a domain-general world model agent. |
| DreamerV2 vs DreamerV3 | DreamerV2 vs DreamerV3 | The Dreamer lineage's two most impactful iterations: DreamerV2 achieved human-level Atari with discrete representations, while DreamerV3 eliminated hyperparameter tuning entirely with symlog predictions. |

This model page synthesizes primary papers, official model pages, benchmark evidence, and related world-models.io context into a reference resource.
Each editorial page is assembled from primary sources, normalized into extractable summaries, checked for factual drift, and reviewed before publication or major refreshes. Last reviewed: 2026-02-05.
Pages are refreshed when a new paper, benchmark, release, architecture update, or stronger primary source materially changes the answer a reader or AI system should retrieve.
Each page links back to relevant primary sources and keeps a stable canonical URL so readers can verify claims, trace context, and reference the most up-to-date version. See the editorial policy.
