Mallea: Building, Steering, and Memorizing Worlds with Coding Agent

Read the original on arXiv AI →

Mallea is a system that builds, steers, and memorizes worlds from text by using a coding agent that infers object interaction requirements and plans object structure, properties, and rules for compact representations. The world evolves under these rules, with optional user actions steering it and text requests editing properties or extending capabilities while preserving unaffected state. Object texture memory retains reusable appearance for whitebox-defined objects and adapts it as those objects change, while a generative renderer combines current structure with remembered appearance to advance the world state.

Code Plans, Diffusion Renders: Open-Ended Generative World Modeling

The paper introduces CoDeR, a new paradigm for world modeling that explicitly builds an executable world using code rather than relying solely on visual observations. CoDeR translates high‑level concepts into structured world rules, executable dynamics, and perceptual observations through five complementary roles, enabling long‑term memory, open‑ended interactions, autonomous world evolution, and persistent multi‑agent dynamics. Experiments show that this framework extends the capabilities of existing world models and achieves state‑of‑the‑art performance across multiple evaluation settings.

BoxWorld: Let World Engines Control and Video Generators Render

BoxWorld introduces a novel approach to real‑time interactive video worlds by decoupling interaction reasoning from generative rendering. A coding agent builds a Box World Engine that applies user‑defined rules to determine interaction outcomes and exposes object states via a lightweight interface of layout boxes, persistent attributes, and dynamic status variables. A separate Box‑State Generative Renderer then autoregressively renders these evolving states into video, enabling online control over object motion, state switches, and conditional events. The system employs a three‑stage training strategy—learning object grounding from open‑domain videos, state transitions from gameplay videos, and rollout distillation on self‑generated histories—to handle real‑time state updates while maintaining visual coherence. BoxWorld outperforms end‑to‑end world models and remains competitive across multiple public benchmarks, with a new PairedStateBench benchmark for fine‑grained interaction control.

StateCraft: Augmenting Video World Models with Abstract-State Reasoning

StateCraft introduces a new architecture that separates a persistent, updatable abstract state from the visual state in video world models. By pairing a language model with a video diffusion model, it tracks entity changes over time and conditions visual generation on this abstract state. The approach is evaluated on generative interfaces and a new benchmark, showing improved generation quality, memory usage, and controllability, while enabling direct editing of unseen states and extending to spatial 3D environments.
