When World Models Meet Transformers: From RSSM to Large-Scale Sequence Modeling

Wed, 12 Aug 2026 00:00:00 +0000

In previous articles, we covered the RSSM architecture and training techniques in DreamerV3 in depth. RSSM is a classic design in reinforcement learning world models, but if you follow recent research, you’ll notice a clear trend: world models are becoming Transformer-based.

From Google’s UniSim to Wayve’s GAIA-1, from NVIDIA’s Cosmos to solutions from domestic embodied AI teams, the Transformer is emerging as a key technical approach for large-scale world models.
