![One photo in, a world you can walk — HunyuanWorld 1.0](https://onehack.st/uploads/default/original/3X/1/7/17eed2c7af0ce663dcffb060ac5adcb57f45c47c.jpeg)

**Feed it one photo → it builds a 360° 3D world you can walk around in.** 🏞🌀

[HunyuanWorld 1.0](https://github.com/Tencent-Hunyuan/HunyuanWorld-1.0) turns one picture (or one sentence) into an explorable mesh world — roam it, pull objects apart, export it. **2.9k★ · open weights · free.**

### 🎮 TRY IT RIGHT NOW — no GPU, no install

🌊 **[WorldMirror demo](https://huggingface.co/spaces/tencent/HunyuanWorld-Mirror)** — upload a video of your street → 3D world back (Tencent’s own, free)

⚡ **[FlashWorld demo](https://huggingface.co/spaces/imlixinyang/FlashWorld-Demo-Spark)** — one photo or sentence → walkable scene in ~10 seconds (free HF token)

### 🖥 RUN IT YOURSELF

1. open the [repo](https://github.com/Tencent-Hunyuan/HunyuanWorld-1.0) → grab the [weights](https://huggingface.co/tencent/HunyuanWorld-1) → two lines on your photo:

> **🧾 Show the two lines**
>
> `python3 demo_panogen.py --prompt "" --image_path your_photo.png --output_path out`
> 
> `CUDA_VISIBLE_DEVICES=0 python3 demo_scenegen.py --image_path out/panorama.png --labels_fg1 stones --labels_fg2 trees --classes outdoor --output_path out`

1. open `modelviewer.html` → **walk it with WASD**

> **⚙️ Honest requirements**
>
> **1.0 wants a big GPU** (~22GB; free Colab 16GB is too small). **4090?** use **1.0-lite**. Save memory: `--fp8_gemm --fp8_attention` · quick try: `bash scripts/test.sh`. Weights: 4 checkpoints, ~478MB each.
> 
> **No GPU?** the two demos above are your free lane — and ⚡FlashWorld runs under 10GB with `--offload_vae`, so even free Colab handles it.

### 🎒 WHAT COMES OUT

🚶 **A world, not a picture** — 360° roam in the browser  
📦 **Real mesh export** — layered `PLY` / `Draco` for Blender, Unity, Unreal  
🧩 **Objects come apart** — layers split out to move, delete, reshape  
💥 **Sim-ready** — built for collision & fluid pipelines

### 🧬 THE LINEAGE

1.0 (Jul 2025) → lite → [Voyager](https://github.com/Tencent-Hunyuan/HunyuanWorld-Voyager) (RGB-D video) → [FlashWorld](https://github.com/imlixinyang/FlashWorld) (seconds, Apache-2.0) → [HY-World 2.0](https://github.com/Tencent-Hunyuan/HY-World-2.0) (Apr 2026) — video in → world out, playable with physics, imports to Unity/Unreal
