+# Building and Testing Wan Video Generation
+
+This guide walks through building the stable-diffusion.cpp extension with Wan support and running tests.
+
+## Summary
+
+The repository has been successfully cloned, built, and configured with test infrastructure for Wan video generation models (Wan2.1 and Wan2.2).
+
+### What Was Done
+
+1. **Repository Setup**
+   - Cloned: `https://github.com/tetherto/qvac-ext-stable-diffusion.cpp.git`
+   - Location: `~/Documents/qvac-ext-stable-diffusion.cpp`
+   - Initialized git submodules (ggml backend)
+
+2. **Build System**
+   - Created `Makefile` wrapper for CMake
+   - Supports multiple build configurations:
+     - `make build` - CPU only
+     - `make build-metal` - Apple Silicon GPU (Metal)
+     - `make build-cuda` - NVIDIA GPU
+     - `make build-vulkan` - Vulkan GPU
+   - Successfully built with Metal GPU support
+
+3. **Binary Locations**
+   - CLI: `~/Documents/qvac-ext-stable-diffusion.cpp/build/bin/sd-cli`
+   - Server: `~/Documents/qvac-ext-stable-diffusion.cpp/build/bin/sd-server`
+
+4. **Test Infrastructure**
+   - Test directory: `~/Documents/qvac-ext-stable-diffusion.cpp/test-wan/`
+   - Test script: `test-wan/test-wan-models.sh`
+   - Helper functions: `test-wan/wan-functions.sh`
+   - Documentation: `test-wan/README.md`
+   - Model storage: `test-wan/models/`
+   - Output storage: `test-wan/output/`
+
+## Quick Start
+
+### 1. Verify Build
+
+```bash
+~/Documents/qvac-ext-stable-diffusion.cpp/build/bin/sd-cli --help
+```
+
+### 2. Download Models
+
+Download Wan model files to `~/Documents/qvac-ext-stable-diffusion.cpp/test-wan/models/`
+
+**Recommended Starting Models:**
+- `wan2.1_t2v_1.3B_fp16.safetensors` (fast test)
+- `wan_2.1_vae.safetensors` (required)

+
+## Testing Wan Models
+
+### Wan2.1 Text-to-Video (T2V)
+
+**1.3B Model (Fast):**
+```bash
+./build/bin/sd-cli -M vid_gen \
+  --diffusion-model test-wan/models/wan2.1_t2v_1.3B_fp16.safetensors \
+  --vae test-wan/models/wan_2.1_vae.safetensors \
+  --t5xxl test-wan/models/umt5_xxl_fp16.safetensors \
+  -p "a lovely cat" \
+  --video-frames 33 \
+  -W 832 -H 480 \
+  --offload-to-cpu \
+  -o test-wan/output/test.mp4
+```
+
+**14B Model (High Quality):**
+```bash
+./build/bin/sd-cli -M vid_gen \
+  --diffusion-model test-wan/models/wan2.1_t2v_14b_Q8_0.gguf \
+  --vae test-wan/models/wan_2.1_vae.safetensors \
+  --t5xxl test-wan/models/umt5_xxl_Q8_0.gguf \
+  -p "a serene landscape" \
+  --video-frames 33 \
+  -W 832 -H 480 \
+  --offload-to-cpu \
+  -o test-wan/output/test.mp4
+```
+
+### Wan2.1 Image-to-Video (I2V)
+
+```bash
+./build/bin/sd-cli -M vid_gen \
+  --diffusion-model test-wan/models/wan2.1_i2v_14b_480p_Q8_0.gguf \
+  --vae test-wan/models/wan_2.1_vae.safetensors \
+  --t5xxl test-wan/models/umt5_xxl_Q8_0.gguf \
+  --clip_vision test-wan/models/clip_vision_h.safetensors \
+  -i input_image.png \
+  -p "the subject moves" \
+  --video-frames 33 \
+  -W 480 -H 832 \
+  --offload-to-cpu \
+  -o test-wan/output/test.mp4
+```
+
+## Performance Tips
+
+### Memory Optimization
+- Use `--offload-to-cpu` to keep models in RAM
+- Reduce `--video-frames` for shorter videos
+- Use quantized GGUF models (Q8_0, Q5_K_M)
+
+### Speed Optimization
+- Use smaller models (1.3B for testing)
+- Reduce video resolution (`-W 640 -H 360`)
+- Use Metal GPU: Built with `-DSD_METAL=ON`
+
+### Quality Settings
+```bash
+# Fast generation
+--cfg-scale 3.5 --steps 8 --video-frames 16
+
+# Balanced
+--cfg-scale 6.0 --steps 20 --video-frames 33
+
+# High quality
+--cfg-scale 7.5 --steps 30 --video-frames 48
+```
+
+## Model Formats
+
+- **Safetensors** (.safetensors): Higher quality, larger files
+- **GGUF** (.gguf): Quantized, smaller files, faster loading
+
+Quantization levels:
+- `Q8_0`: 8-bit (recommended, good balance)
+- `Q5_K_M`: 5-bit (smaller, acceptable quality)
+- `F16`: 16-bit float (highest quality, largest size)
+
+## Troubleshooting
+
+### Build Issues
+
+**CMake not found:**
+```bash
+brew install cmake
+```
+
+**Metal not working:**
+Verify Metal GPU support:
+```bash
+system_profiler SPDisplaysDataType | grep "Metal"
+```
+
+### Runtime Issues
+
+**Models not found:**
+- Check file names match exactly (case-sensitive)
+- Verify paths in commands
+- Use absolute paths to avoid issues
+
+**Out of memory:**
+- Enable `--offload-to-cpu`
+- Reduce `--video-frames`
+- Use smaller models
+
+**Slow generation:**
+- Verify Metal is being used: `system_profiler SPDisplaysDataType`
+- Try smaller models first (1.3B)
+- Check disk I/O: models may be on slow storage
+
+## Integration with qvac Project
+
+The stable-diffusion.cpp extension can be integrated into the main qvac project:
+
+```bash
+# From qvac root
+cd ~/Documents/qvac
+# Link or copy the built binaries
+ln -s ~/Documents/qvac-ext-stable-diffusion.cpp/build/bin/sd-cli ./bin/sd-cli
+ln -s ~/Documents/qvac-ext-stable-diffusion.cpp/build/bin/sd-server ./bin/sd-server
+```

+
+## Step-by-Step Guide
+
+### Step 1: Verify Everything Works
+
+```bash
+cd ~/Documents/qvac-ext-stable-diffusion.cpp/test-wan
+./verify-setup.sh
+```
+
+You should see all checkmarks (✓).
+
+### Step 2: Download Models
+
+Choose the model you want to start with and download from Hugging Face.
+
+**For Testing (Fastest, ~10 minutes setup):**
+Download these 3 files to `test-wan/models/`:
+1. `wan2.1_t2v_1.3B_fp16.safetensors` (2.5 GB) from [Comfy-Org](https://huggingface.co/Comfy-Org/Wan_2.1_ComfyUI_repackaged/tree/main/split_files/diffusion_models)
+2. `wan_2.1_vae.safetensors` (1.2 GB) from [Comfy-Org](https://huggingface.co/Comfy-Org/Wan_2.1_ComfyUI_repackaged/blob/main/split_files/vae/wan_2.1_vae.safetensors)
+3. `umt5_xxl_fp16.safetensors` (4.6 GB) from [Comfy-Org](https://huggingface.co/Comfy-Org/Wan_2.1_ComfyUI_repackaged/blob/main/split_files/text_encoders/umt5_xxl_fp16.safetensors)
+
+**Total: ~8.3 GB** | **Time to download: 30-60 minutes depending on speed**
+
+See `README.md` for links to other models (14B high-quality, Wan2.2, etc.)
+
+### Step 3: Verify Models Were Downloaded
+
+```bash
+ls -lh ~/Documents/qvac-ext-stable-diffusion.cpp/test-wan/models/
+```
+
+You should see the three model files listed.
+
+### Step 4: Run Your First Test
+
+```bash
+cd ~/Documents/qvac-ext-stable-diffusion.cpp/test-wan
+./test-wan-models.sh wan2-1-t2v-small
+```
+
+**What to expect:**
+- First run initializes everything (may take a minute)
+- The model gets loaded into GPU memory
+- Video generation starts
+- Output saved to `output/wan2-1-t2v-1.3b-test.mp4`
+
+**Estimated time: 30-60 seconds on Apple Silicon M-series**
+
+### Step 5: Check the Generated Video
+
+```bash
+open ~/Documents/qvac-ext-stable-diffusion.cpp/test-wan/output/wan2-1-t2v-1.3b-test.mp4
+```
+
+## Using Helper Functions
+
+Add these to your shell for easy video generation:
+
+```bash
+# Add to your shell profile (~/.zshrc or ~/.bashrc)
+source ~/Documents/qvac-ext-stable-diffusion.cpp/test-wan/wan-functions.sh
+```
+
+Then use:
+
+```bash
+# Generate a quick video
+wan_t2v_small "a cat playing with a ball" ~/my_video.mp4
+
+# Generate high-quality video (slower)
+wan_t2v_large "a sunset over mountains" ~/my_video.mp4
+
+# Animate an image
+wan_i2v ~/image.png "the person dances" ~/my_video.mp4
+
+# Show help
+wan_help
+
+# Run benchmark
+wan_benchmark small
+```
+
+## Customizing Video Generation
+
+### Simple Command
+
+```bash
+~/Documents/qvac-ext-stable-diffusion.cpp/build/bin/sd-cli -M vid_gen \
+  --diffusion-model ~/Documents/qvac-ext-stable-diffusion.cpp/test-wan/models/wan2.1_t2v_1.3B_fp16.safetensors \
+  --vae ~/Documents/qvac-ext-stable-diffusion.cpp/test-wan/models/wan_2.1_vae.safetensors \
+  --t5xxl ~/Documents/qvac-ext-stable-diffusion.cpp/test-wan/models/umt5_xxl_fp16.safetensors \
+  -p "your prompt here" \
+  -o output.mp4
+```
+
+### Full Command with Options
+
+```bash
+~/Documents/qvac-ext-stable-diffusion.cpp/build/bin/sd-cli -M vid_gen \
+  --diffusion-model models/wan2.1_t2v_1.3B_fp16.safetensors \
+  --vae models/wan_2.1_vae.safetensors \
+  --t5xxl models/umt5_xxl_fp16.safetensors \
+  -p "a cat jumping over a fence" \
+  --cfg-scale 6.0 \          # Prompt strength (higher = stricter adherence)
+  --sampling-method euler \   # Sampling algorithm
+  --steps 20 \               # Diffusion steps (higher = better quality)
+  --video-frames 33 \        # Number of frames (33 = ~1.3 seconds at 24fps)
+  --flow-shift 3.0 \         # Motion dynamics
+  -W 832 -H 480 \            # Resolution
+  --diffusion-fa \           # Flash attention (faster, less memory)
+  --offload-to-cpu \         # Store models in RAM, load to GPU when needed
+  -o output.mp4
+```
+
+## Troubleshooting
+
+### Models Not Found
+Make sure file names match exactly (case-sensitive):
+- ✓ `wan2.1_t2v_1.3B_fp16.safetensors`
+- ✗ `Wan2.1_t2v_1.3b.safetensors` (wrong case/name)
+
+### Out of Memory
+```bash
+# Reduce frames for shorter videos
+--video-frames 16
+
+# Reduce resolution
+-W 640 -H 360
+
+# Enable CPU offloading (slightly slower)
+--offload-to-cpu
+```
+
+### Very Slow Generation
+- Verify Metal GPU is being used: `system_profiler SPDisplaysDataType | grep Metal`
+- Try smaller model (1.3B instead of 14B)
+- Check disk speed (models may be on slow storage)
+
+### No GPU Acceleration
+The project was built with Metal support:
+```bash
+# Verify build configuration
+file ~/Documents/qvac-ext-stable-diffusion.cpp/build/bin/sd-cli
+# Should show: "Mach-O 64-bit executable arm64"
+```
+
+## Model Comparison
+
+| Model | Size | Speed | Quality | VRAM | Best For |
+|-------|------|-------|---------|------|----------|
+| Wan2.1 1.3B | 2.5 GB | 30-60s | Good | 4 GB | Testing, quick videos |
+| Wan2.1 14B | 7.5 GB | 3-5 min | Excellent | 8-16 GB | High quality results |
+| Wan2.2 TI2V 5B | 5.0 GB | 1-2 min | Good | 6 GB | Mobile-friendly |
+| Wan2.1 I2V 14B | 7.5 GB | 3-5 min | Excellent | 8-16 GB | Animating images |
+
+## Next Steps
+
+1. ✅ **Verify setup** → Run `verify-setup.sh`
+2. ⬇️ **Download models** → See Step 2 above
+3. ▶️ **Generate first video** → Run test command
+4. 🎨 **Customize prompts** → Try your own descriptions
+5. 📊 **Benchmark performance** → Run `wan_benchmark small`
+6. 📚 **Explore options** → See README.md for advanced features
+
+## Performance Tips
+
+### For Speed
+```bash
+--cfg-scale 3.5      # Lower = faster, less precise
+--steps 8            # Fewer steps = faster but lower quality
+--video-frames 16    # Shorter videos
+-W 640 -H 360        # Lower resolution
+```
+
+### For Quality
+```bash
+--cfg-scale 7.5      # Higher = stricter adherence to prompt
+--steps 30           # More steps = better quality
+--video-frames 48    # More frames = smoother motion
+-W 832 -H 480        # Higher resolution
+```
+
+### For Memory
+```bash
+--offload-to-cpu     # Load models from RAM on demand
+--vae-tiling         # Process VAE in tiles

+# Wan Video Generation Tests
+
+This directory contains test configurations for running Wan video generation models with the `stable-diffusion.cpp` engine.
+
+## Prerequisites
+
+1. Build the project with Metal support:
+   ```bash
+   cd ~/Documents/qvac-ext-stable-diffusion.cpp
+   make build-metal
+   ```
+
+2. Download model files to the `models/` directory
+
+## Model Downloads

+  - File: `wan2.2_vae.safetensors`
+
+#### Text Encoder (T5-XXL)
+

+
+## Running Tests
+
+### Test All Models (if available)
+
+```bash
+./test-wan-models.sh all
+```
+
+### Test Specific Model
+
+```bash
+# Wan2.1 T2V 1.3B (fastest, good for testing)
+./test-wan-models.sh wan2-1-t2v-small
+
+# Wan2.1 T2V 14B (highest quality, requires more VRAM)
+./test-wan-models.sh wan2-1-t2v-large
+
+# Wan2.2 TI2V 5B (balanced)
+./test-wan-models.sh wan2-2-t2v
+
+# Wan2.1 I2V 14B (image-to-video)
+./test-wan-models.sh wan2-1-i2v
+```
+
+## Output
+
+Generated videos will be saved in the `output/` directory:
+- `wan2-1-t2v-1.3b-test.mp4`
+- `wan2-1-t2v-14b-test.mp4`
+- `wan2-2-ti2v-5b-test.mp4`
+- `wan2-1-i2v-14b-test.mp4`
+
+## Performance Notes
+
+### Memory Requirements (VRAM)
+
+- **Wan2.1 1.3B**: ~4-6 GB
+- **Wan2.1 14B**: ~8-16 GB
+- **Wan2.2 5B**: ~6-8 GB
+
+### Tips for Optimization
+
+1. **Reduce Video Frames**: Lower `--video-frames` (default: 33)
+   ```bash
+   --video-frames 16  # Faster, shorter videos
+   ```
+
+2. **Offload to CPU**: Keep models in RAM, load to VRAM as needed
+   ```bash
+   --offload-to-cpu  # Already enabled in test script
+   ```
+
+3. **Use GGUF Quantized Models**: Smaller file sizes, less VRAM
+   - `Q8_0` quantization: ~8-bit precision (recommended)
+   - `Q5_K_M` quantization: ~5-bit precision (even smaller)
+
+4. **Reduce Resolution**: Lower output dimensions
+   ```bash
+   -W 640 -H 360  # Instead of 832x480
+   ```
+
+## Troubleshooting
+
+### Model not found
+Ensure all required files are downloaded to the `models/` directory with exact filenames.
+
+### Out of memory
+- Reduce `--video-frames`
+- Enable `--offload-to-cpu`
+- Use lower resolution
+- Use quantized models (GGUF format)
+
+### Slow generation
+- Metal GPU acceleration requires macOS with Apple Silicon
+- Verify Metal is being used: `system_profiler SPDisplaysDataType`
+- Consider using smaller models (1.3B or 5B instead of 14B)
+
+## Command Reference
+
+### Basic Text-to-Video
+```bash
+./build/bin/sd-cli -M vid_gen \
+  --diffusion-model model.gguf \
+  --vae vae.safetensors \

Subject: [PATCH 3/3] ggml: bump submodule to feature/metal-pr-16669-clean for
 Wan Metal ops

Bumps the ggml submodule to tetherto/qvac-ext-ggml@feature/metal-pr-16669-clean,
which adds the two Metal ops actually required by Wan video diffusion:

  - IM2COL_3D (3D im2col for Wan VAE/transformer 3D convs)
  - PAD left-padding support (Wan input preprocessing)

Without this, the Metal backend crashes during Wan inference with:
    ggml_metal_op_encode_impl: error: unsupported op 'IM2COL_3D'

Why no DIAG_MASK_INF Metal kernel
---------------------------------
The original CLDawes patch (ggml-org/llama.cpp#16669) bundled a Metal
DIAG_MASK_INF kernel along with IM2COL_3D + PAD. It is intentionally
not pulled in here because:

  - GGML_OP_DIAG_MASK_INF is being deprecated upstream in favor of
    generic ops (ggml-org/llama.cpp#17654), and ggerganov has steered
    contributors away from new DIAG_MASK_INF backend kernels
    (ggml-org/ggml#1395).
  - leejet/stable-diffusion.cpp#1230 (already in our base, merged
    Jan 2026) refactored every CLIP / SD / MMDiT / RoPE / VAE
    attention site to build explicit -INFINITY mask tensors and
    removed all `diag_mask_inf=true` calls. There are zero
    ggml_diag_mask_inf call sites left in app code.
  - All ggml_ext_attention_ext(...) calls in src/wan.hpp pass
    mask = nullptr, so a Metal DIAG_MASK_INF kernel would be dead
    code on this stack.

Other changes
-------------
  - Point .gitmodules at tetherto/qvac-ext-ggml so clones can fetch
    the patched submodule directly.
  - Ignore test-wan/output/, test-wan/models/, and test-wan/cache/
    so generated videos, downloaded weights, and model caches are
    not accidentally committed.

Verified on Apple M3 Ultra: Wan2.1 1.3B txt2video runs end-to-end
on Metal with the host process at 0-1.5% CPU throughout.
