✨ Contributions

• A comprehensive evaluation framework with 289 cases, 1,058 interaction turns, covering 4 interaction types (navigation, subject action, event editing, perspective switching) across diverse scenes and perspectives.
• A unified navigation protocol that bridges text, 6-DoF camera pose, and discrete-action interfaces, enabling fair comparison across model families.
• 22 automatic metrics spanning 5 complementary dimensions, validated against human judgments, ensuring reliable automatic evaluation at scale.
• Systematic diagnosis of 39 models revealing that current world models have not yet unified high-fidelity rendering with reliable controllability, consistency, and physics compliance.

🚀 Quick Start

# Install
git clone --recursive https://github.com/meituan-longcat/WBench.git
cd WBench

# If you already cloned without submodules
git submodule update --init --recursive

# Download data and weights
pip install huggingface_hub
hf download meituan-longcat/WBench --repo-type dataset --local-dir data/ --exclude "splits/*"
hf download meituan-longcat/WBench-weights --local-dir weights/

# Environment 1: wbench-main (all metrics except visual_plausibility)
# 2nd arg = PyTorch's CUDA build — match it to YOUR system (check via `nvcc --version`):
#   cu124 → CUDA 12.x    cu121 → CUDA 12.1    cu118 → CUDA 11.8
# Always pass it explicitly: if omitted, auto-detection falls back to cu118 when nvcc
# isn't on PATH, which makes the MegaSAM CUDA extensions fail to build on CUDA-12 machines.
bash tools/install.sh wbench-main cu124
conda activate wbench-main
export LD_LIBRARY_PATH=$CONDA_PREFIX/lib:$LD_LIBRARY_PATH



# Verify
conda activate wbench-main
python tools/verify_install.py

# Run evaluation (auto multi-GPU)
python main.py --model your_model

See docs/installation.md for detailed setup instructions.

🎮 Evaluate Your Model

Set environment variables for VLM metrics first (we use Doubao-Seed-2.0-lite via Volcengine ARK):

export VLM_API_KEY="<your-ark-api-key>"
# Optional (defaults shown):
# export VLM_API_URL="https://ark.cn-beijing.volces.com/api/v3"
# export VLM_MODEL_NAME="doubao-seed-2-0-lite-260215"

1. Generate multi-turn videos → place in work_dirs/<model>/videos/case_{id}_combined.mp4
2. Run the 3-phase pipeline:

# Full pipeline (precompute → GPU metrics → VLM metrics → report)
python main.py --model my_model --gpus 0,1,2,3,4,5,6,7

# Or run phases independently:
python main.py --model my_model --phase precompute    # SAM2 + DA3 + MegaSAM
python main.py --model my_model --phase gpu           # GPU metrics (per-metric)
python main.py --model my_model --phase vlm           # VLM metrics (API)
python main.py --model my_model --phase report        # Aggregate report

Note: the pipeline above covers 21 of the 22 metrics. visual_plausibility is the exception — it runs in the separate wbench-vp environment (set up in Quick Start):

conda activate wbench-vp
python tools/run_visual_plausibility.py --model my_model  # uses all available GPUs

3. Results: work_dirs/<model>/evaluation/{metric}/case_{id}.json + report.json

# Run specific metrics (by name or dimension)
python main.py --model my_model --phase gpu --metrics hpsv3_quality
python main.py --model my_model --phase gpu --metrics quality         # all 6 video quality
python main.py --model my_model --phase gpu --metrics consistency     # all consistency metrics

# Skip pre-computation if already done
python main.py --model my_model --phase gpu --skip_megasam --skip_sam2 --skip_da3

# Single video evaluation
python main.py --video video.mp4 --case data/cases/case_1.json

Dimensions (--metrics supports these as shorthand):

Dimension	Metrics
quality	aesthetic_quality, imaging_quality, temporal_flickering, dynamic_degree, motion_smoothness, hpsv3_quality
consistency	background_consistency, segment_continuity, perspective_consistency, subject_consistency, geometric_consistency, photometric_consistency, spatial_consistency, gated_spatial_consistency
interaction	navigation_trajectory, event_edit_adherence, subject_action_adherence, perspective_switch_adherence
setting	scene_adherence, subject_adherence
physical	visual_plausibility, causal_fidelity

🔌 Implement Your Model

WBench supports 3 model types with different control interfaces:

Type	Input	Cases	Status
Text-conditioned	Text prompt + first-frame image	289 (all)	✅ Implemented
Camera-conditioned	First-frame image + 6-DoF camera pose	158 (navi)	✅ Implemented
Action-conditioned	First-frame image + discrete action	158 (navi)	✅ Implemented

Text-conditioned models

from src.models import get_model

# Available: wan, kling, seedance (or register your own)
model = get_model("wan")

# Generate multi-turn video from a case
result = model.generate_multi_turn(
    case=case_dict,
    output_path="work_dirs/wan/videos/case_1_combined.mp4",
    data_root="data/",
)

Each turn: build prompt from interaction → call I2V API → extract last frame → next turn.

Set API credentials:

export VIDEO_API_URL="https://your-video-api.com"
export VIDEO_API_KEY="your-key"

Camera-conditioned models

The benchmark's navigation actions (W/A/S/D + arrows) are converted to per-turn {move, yaw, pitch} intent and then to a 6-DoF camera trajectory. Subclass CameraConditionedModel and implement one hook — case parsing, action→pose conversion, and video writing are handled for you:

from src.models.camera import CameraConditionedModel

class MyWorldModel(CameraConditionedModel):
    def generate_with_poses(self, image, poses, video_length, **kw):
        # image: first-frame path; poses: {"<latent_idx>": {"extrinsic": 4x4, "K": 3x3}, ...}
        # return: list of `video_length` BGR uint8 frames
        return my_model.infer(image, poses, video_length)

MyWorldModel("mymodel").generate_multi_turn(case_dict,
    "work_dirs/mymodel/videos/case_1_combined.mp4", data_root="data/")

The pose convention (axes, speeds, intrinsics) lives in src/models/camera/poses.py — copy and adapt it to your model; the navigation metric normalises scale, so what matters is matching the per-action intent. Quick look at one case:

python -m src.models.camera.demo --case data/cases/case_1.json   # prints poses + renders a preview

Note: Camera/action models only cover the 158 navigation cases (cases containing at least one W/A/S/D/arrow action). When generating at scale, pass only those cases — e.g. via generate.py --model your_model --cases <navi_list>.

Action-conditioned models

Two flavours, both fed from the same per-turn navigation plan:

Programmatic controllers (e.g. Matrix-Game-3). Subclass ActionConditionedModel and implement generate_with_actions. Each action carries both raw key tokens and an MG3-style {keyboard, mouse} tensor:

from src.models.action import ActionConditionedModel

class MyActionModel(ActionConditionedModel):
    def generate_with_actions(self, image, actions, video_length, **kw):
        # actions: [{"turn", "tokens", "keyboard", "mouse", "duration"}, ...]
        return my_model.infer(image, actions, video_length)

MyActionModel("mymodel").generate_multi_turn(case_dict,
    "work_dirs/mymodel/videos/case_1_combined.mp4", data_root="data/")

python -m src.models.action.demo --case data/cases/case_1.json   # prints actions + renders a preview

Web products (e.g. Project Genie, Happy Oyster) — no weights/API; driven by browser automation + simulated keystrokes. See src/models/action/web/.

🤖 Claude Code Skills

If you use Claude Code, this repo ships skills that drive the full workflow — just ask in natural language and Claude runs the right commands:

Skill	Triggers on	What it does
wbench-generate	"generate kling videos"	Runs generate.py over the dataset → work_dirs/<model>/videos/
wbench-evaluate	"evaluate kling3"	Runs the 4-phase main.py pipeline (precompute → gpu → vlm → report)
wbench-submit	"package my model for submission"	Builds the meta.json / turns.json bundle and uploads to HuggingFace
genie3 / happy	"run case_5 on genie3"	Browser automation for the web products (details)

Skills live in .claude/skills/ (and src/models/action/web/.claude/skills/) and are auto-discovered when you open the repo in Claude Code.
