MKD2World: A Typed Spatial MarkDown World Model For Web Agents

MKD2World introduces Typed Spatial Markdown (TSM), a Markdown-style textual representation that serializes desktop web interface elements by type, visual semantics, location, and hierarchy. Using the AtomBlock-WebUI dataset, a screenshot-to-TSM renderer is trained, enabling a two-stage world model that predicts current and next states for GUI agents. The resulting MKD2World-9B model outperforms GPT-5.6-Sol on EleF1 and boosts the success rate of a Qwen3.5-35B web agent on Online-Mind2Web tasks.

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.
