The New Game Engine Isn’t Unity. It’s the World Model. Why the next leap in “world models” won’t come from bigger token budgets, but from smarter missing-information games.

The real shift isn’t AI content. It’s AI worlds: consistent state, object dynamics, and project structure you can actually ship.

KL‑Regularization Boosts Adaptive Planning in Model‑Based RL

PO‑MPC adds a KL‑divergence term to align policies with MPPI planners, weighting the KL to boost sample efficiency and stabilize learning on continuous‑control benchmarks. Read more: getnews.me/kl-regularization-boosts... #modelbasedrl #klregularization

Pre‑trained Vision Models Improve Generalization in Model‑Based RL

Pre‑trained vision models boost robustness of model‑based RL under severe visual domain shifts; partial fine‑tuning of higher layers gives the best performance. Read more: getnews.me/pre-trained-vision-model... #pretrainedvision #modelbasedrl

This was an amazing collaboration with a cracked team consisting of @cvoelcker.bsky.social, me, Arash Ahmadian, Romina Abachi, @igilitschenski.bsky.social, and @sologen.bsky.social
