Playable World Models

Agora-1

Odyssey

Multi-agent world model for multiple human or AI participants in one real-time simulation.

AlayaWorld

Alaya Lab

Interactive autoregressive world model with real-time camera control, prompt switching, and long-horizon memory consistency. Open-source, sustains interactive play past the one-minute mark.

Cosmos 3

NVIDIA

Omnimodal world-model family for physical AI spanning language, image, video, audio and action.

Genie 3

Google DeepMind

General-purpose world model generating photorealistic environments from text with real-time exploration.

HY-World 1.5 (WorldPlay)

Tencent Hunyuan

Tencent Hunyuan's streaming video diffusion model for real-time, interactive world modeling with long-term geometric consistency, released as WorldPlay. Given a single image or text prompt, it generates a next-chunk (16-frame) video prediction conditioned on live user keyboard/mouse actions, dynamically reconstituting context memory from past frames to keep the world geometrically consistent over long sessions. Runs at up to 24fps in first- or third-person, across real-world and stylized scenes. Open-sourced (code, weights, and full training pipeline). Predecessor to, and released separately from, the later HY-World 2.0.

HY-World 2.0

Tencent Hunyuan

Multi-modal world model framework for world generation and world reconstruction — accepts text, single-view images, multi-view images, and video to produce editable, persistent 3D world representations (meshes / 3D Gaussian Splatting) compatible with game engines (Blender, Unity, Unreal).

Khora

Ophilus

A scalable multiplayer world model for shared AI worlds, built by Ophilus in collaboration with RhOS.ai. Supports arbitrary player populations with linear-time complexity while keeping a coherent shared world across players during fast movement, elevation changes, and combat. Whether the demo's map geometry is generated live per-session, or a fixed environment streamed in real time, has not been independently confirmed — the live multiplayer interactivity itself has been.

LTX-2.5

Lightricks

Lightricks' 22-billion-parameter open-weights audio-video generation model, released August 11, 2026. Turns text, image, and video inputs into synchronized, high-fidelity video and audio in a single pass, including native multishot generation (connected scenes with consistent character/style across cuts). Positioned by Lightricks and press coverage as a "world model" for video, robotics and simulation, distinct from this catalogue's live-interactive world models (Marble, MIRA, PAN, WorldPlay) — see research notes for the classification nuance.

Lucy 2.5

Decart

Real-time world editing/transformation model for live immersive video experiences.

Marble 1.0 Draft

World Labs

Fast Marble variant for rapid exploration.

Marble 1.1

World Labs

World Labs world-generation model with improved quality at fixed generation cost.

Marble 1.1 Plus

World Labs

Advanced Marble model from World Labs for larger persistent 3D worlds.

Oasis 3

Decart

Interactive world model for physical AI with controllable multi-view simulation in real time.

Odyssey-2

Odyssey

General-purpose real-time world model generating interactive simulations from text or image prompts.

Waypoint-1.5

Overworld

Overworld's real-time video world model for consumer GPUs: a 1.2B-parameter autoregressive diffusion transformer generating interactive 720p/60fps video from keyboard and mouse input, with a 512-frame context window. Released open-weight under Apache 2.0 on Hugging Face in 1B and 1B-360P tiers. The hosted overworld.stream platform requires an account to play; the model weights themselves do not.
