Feed it one photo → it builds a 360° 3D world you can walk around in. 
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 — upload a video of your street → 3D world back (Tencent’s own, free)
FlashWorld demo — one photo or sentence → walkable scene in ~10 seconds (free HF token)

⚙️ 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 (RGB-D video) → FlashWorld (seconds, Apache-2.0) → HY-World 2.0 (Apr 2026) — video in → world out, playable with physics, imports to Unity/Unreal
