+
+### Build
+
+#### Build from scratch
+
+```shell
+mkdir build
+cd build
+cmake ..
+cmake --build . --config Release
+```
+
+##### Using OpenBLAS
+
+```
+cmake .. -DGGML_OPENBLAS=ON
+cmake --build . --config Release
+```
+
+##### Using CUDA
+
+This provides BLAS acceleration using the CUDA cores of your Nvidia GPU. Make sure to have the CUDA toolkit installed. You can download it from your Linux distro's package manager (e.g. `apt install nvidia-cuda-toolkit`) or from here: [CUDA Toolkit](https://developer.nvidia.com/cuda-downloads). Recommended to have at least 4 GB of VRAM.
+
+```
+cmake .. -DSD_CUDA=ON
+cmake --build . --config Release
+```
+
+##### Using HipBLAS
+This provides BLAS acceleration using the ROCm cores of your AMD GPU. Make sure to have the ROCm toolkit installed.
+
+Windows User Refer to [docs/hipBLAS_on_Windows.md](docs%2FhipBLAS_on_Windows.md) for a comprehensive guide.
+
+```
+cmake .. -G "Ninja" -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DSD_HIPBLAS=ON -DCMAKE_BUILD_TYPE=Release -DAMDGPU_TARGETS=gfx1100 -DCMAKE_BUILD_WITH_INSTALL_RPATH=ON
+cmake --build . --config Release
+```
+
+##### Using MUSA
+
+This provides BLAS acceleration using the MUSA cores of your Moore Threads GPU. Make sure to have the MUSA toolkit installed.
+
+```bash
+cmake .. -DCMAKE_C_COMPILER=/usr/local/musa/bin/clang -DCMAKE_CXX_COMPILER=/usr/local/musa/bin/clang++ -DSD_MUSA=ON -DCMAKE_BUILD_TYPE=Release
+cmake --build . --config Release
+```
+
+##### Using Metal
+
+Using Metal makes the computation run on the GPU. Currently, there are some issues with Metal when performing operations on very large matrices, making it highly inefficient at the moment. Performance improvements are expected in the near future.
+
+```
+cmake .. -DSD_METAL=ON
+cmake --build . --config Release
+```
+
+##### Using Vulkan
+
+Install Vulkan SDK from https://www.lunarg.com/vulkan-sdk/.
+
+```
+cmake .. -DSD_VULKAN=ON
+cmake --build . --config Release
+```
+
+##### Using OpenCL (for Adreno GPU)
+
+Currently, it supports only Adreno GPUs and is primarily optimized for Q4_0 type
+
+To build for Windows ARM please refers to [Windows 11 Arm64
+](https://github.com/ggml-org/llama.cpp/blob/master/docs/backend/OPENCL.md#windows-11-arm64)
+
+Building for Android:
+
+  Android NDK:
+       Download and install the Android NDK from the [official Android developer site](https://developer.android.com/ndk/downloads).
+
+Setup OpenCL Dependencies for NDK:
+
+You need to provide OpenCL headers and the ICD loader library to your NDK sysroot.
+
+*   OpenCL Headers:
+    ```bash
+    # In a temporary working directory
+    git clone https://github.com/KhronosGroup/OpenCL-Headers
+    cd OpenCL-Headers
+    # Replace <YOUR_NDK_PATH> with your actual NDK installation path
+    # e.g., cp -r CL /path/to/android-ndk-r26c/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include
+    sudo cp -r CL <YOUR_NDK_PATH>/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include
+    cd ..
+    ```
+
+*   OpenCL ICD Loader:
+    ```bash
+    # In the same temporary working directory
+    git clone https://github.com/KhronosGroup/OpenCL-ICD-Loader
+    cd OpenCL-ICD-Loader
+    mkdir build_ndk && cd build_ndk
+
+    # Replace <YOUR_NDK_PATH> in the CMAKE_TOOLCHAIN_FILE and OPENCL_ICD_LOADER_HEADERS_DIR
+    cmake .. -G Ninja -DCMAKE_BUILD_TYPE=Release \
+      -DCMAKE_TOOLCHAIN_FILE=<YOUR_NDK_PATH>/build/cmake/android.toolchain.cmake \
+      -DOPENCL_ICD_LOADER_HEADERS_DIR=<YOUR_NDK_PATH>/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include \
+      -DANDROID_ABI=arm64-v8a \
+      -DANDROID_PLATFORM=24 \
+      -DANDROID_STL=c++_shared
+
+    ninja
+    # Replace <YOUR_NDK_PATH>
+    # e.g., cp libOpenCL.so /path/to/android-ndk-r26c/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android
+    sudo cp libOpenCL.so <YOUR_NDK_PATH>/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android
+    cd ../..
+    ```
+
+Build `stable-diffusion.cpp` for Android with OpenCL:
+
+```bash
+mkdir build-android && cd build-android
+
+# Replace <YOUR_NDK_PATH> with your actual NDK installation path
+# e.g., -DCMAKE_TOOLCHAIN_FILE=/path/to/android-ndk-r26c/build/cmake/android.toolchain.cmake
+cmake .. -G Ninja \
+  -DCMAKE_TOOLCHAIN_FILE=<YOUR_NDK_PATH>/build/cmake/android.toolchain.cmake \
+  -DANDROID_ABI=arm64-v8a \
+  -DANDROID_PLATFORM=android-28 \
+  -DGGML_OPENMP=OFF \
+  -DSD_OPENCL=ON
+
+ninja
+```
+*(Note: Don't forget to include `LD_LIBRARY_PATH=/vendor/lib64` in your command line before running the binary)*
+
+##### Using SYCL
+
+Using SYCL makes the computation run on the Intel GPU. Please make sure you have installed the related driver and [Intel® oneAPI Base toolkit](https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit.html) before start. More details and steps can refer to [llama.cpp SYCL backend](https://github.com/ggerganov/llama.cpp/blob/master/docs/backend/SYCL.md#linux).
+
+```
+# Export relevant ENV variables
+source /opt/intel/oneapi/setvars.sh
+
+# Option 1: Use FP32 (recommended for better performance in most cases)
+cmake .. -DSD_SYCL=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx
+
+# Option 2: Use FP16
+cmake .. -DSD_SYCL=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx -DGGML_SYCL_F16=ON
+
+cmake --build . --config Release
+```
+
+Example of text2img by using SYCL backend:
+
+- download `stable-diffusion` model weight, refer to [download-weight](#download-weights).
+
+- run `./bin/sd -m ../models/sd3_medium_incl_clips_t5xxlfp16.safetensors --cfg-scale 5 --steps 30 --sampling-method euler  -H 1024 -W 1024 --seed 42 -p "fantasy medieval village world inside a glass sphere , high detail, fantasy, realistic, light effect, hyper detail, volumetric lighting, cinematic, macro, depth of field, blur, red light and clouds from the back, highly detailed epic cinematic concept art cg render made in maya, blender and photoshop, octane render, excellent composition, dynamic dramatic cinematic lighting, aesthetic, very inspirational, world inside a glass sphere by james gurney by artgerm with james jean, joe fenton and tristan eaton by ross tran, fine details, 4k resolution"`

+
+
+
+##### Using Flash Attention
+
+Enabling flash attention for the diffusion model reduces memory usage by varying amounts of MB.
+eg.:
+ - flux 768x768 ~600mb
+ - SD2 768x768 ~1400mb
+
+For most backends, it slows things down, but for cuda it generally speeds it up too.
+At the moment, it is only supported for some models and some backends (like cpu, cuda/rocm, metal).
+
+Run by adding `--diffusion-fa` to the arguments and watch for:
+```
+[INFO ] stable-diffusion.cpp:312  - Using flash attention in the diffusion model
+```
+and the compute buffer shrink in the debug log:
+```
+[DEBUG] ggml_extend.hpp:1004 - flux compute buffer size: 650.00 MB(VRAM)
+```

-
-## Build (CPU only)
-
-If you don't have a GPU or CUDA installed, you can build a CPU-only version.
-
-```shell
-mkdir build && cd build
-cmake ..
-cmake --build . --config Release
-```
-
-## Build with OpenBLAS
-
-```shell
-mkdir build && cd build
-cmake .. -DGGML_OPENBLAS=ON
-cmake --build . --config Release
-```
-
-## Build with CUDA
-
-This provides GPU acceleration using NVIDIA GPU. Make sure to have the CUDA toolkit installed. You can download it from your Linux distro's package manager (e.g. `apt install nvidia-cuda-toolkit`) or from here: [CUDA Toolkit](https://developer.nvidia.com/cuda-downloads). Recommended to have at least 4 GB of VRAM.
-
-```shell
-mkdir build && cd build
-cmake .. -DSD_CUDA=ON
-cmake --build . --config Release
-```
-
-## Build with HipBLAS
-
-This provides GPU acceleration using AMD GPU. Make sure to have the ROCm toolkit installed.
-To build for another GPU architecture than installed in your system, set `$GFX_NAME` manually to the desired architecture (replace first command). This is also necessary if your GPU is not officially supported by ROCm, for example you have to set `$GFX_NAME` manually to `gfx1030` for consumer RDNA2 cards.
-
-Windows User Refer to [docs/hipBLAS_on_Windows.md](docs%2FhipBLAS_on_Windows.md) for a comprehensive guide.
-
-```shell
-mkdir build && cd build
-if command -v rocminfo; then export GFX_NAME=$(rocminfo | awk '/ *Name: +gfx[1-9]/ {print $2; exit}'); else echo "rocminfo missing!"; fi
-if [ -z "${GFX_NAME}" ]; then echo "Error: Couldn't detect GPU!"; else echo "Building for GPU: ${GFX_NAME}"; fi

-cmake --build . --config Release
-```
-
-## Build with MUSA
-
-This provides GPU acceleration using Moore Threads GPU. Make sure to have the MUSA toolkit installed.
-
-```shell
-mkdir build && cd build
-cmake .. -DCMAKE_C_COMPILER=/usr/local/musa/bin/clang -DCMAKE_CXX_COMPILER=/usr/local/musa/bin/clang++ -DSD_MUSA=ON -DCMAKE_BUILD_TYPE=Release
-cmake --build . --config Release
-```
-
-## Build with Metal
-
-Using Metal makes the computation run on the GPU. Currently, there are some issues with Metal when performing operations on very large matrices, making it highly inefficient at the moment. Performance improvements are expected in the near future.
-
-```shell
-mkdir build && cd build
-cmake .. -DSD_METAL=ON
-cmake --build . --config Release
-```
-
-## Build with Vulkan
-
-Install Vulkan SDK from https://www.lunarg.com/vulkan-sdk/.
-
-```shell
-mkdir build && cd build
-cmake .. -DSD_VULKAN=ON
-cmake --build . --config Release
-```
-
-## Build with OpenCL (for Adreno GPU)
-
-Currently, it supports only Adreno GPUs and is primarily optimized for Q4_0 type
-
-To build for Windows ARM please refers to [Windows 11 Arm64](https://github.com/ggml-org/llama.cpp/blob/master/docs/backend/OPENCL.md#windows-11-arm64)
-
-Building for Android:
-
-  Android NDK:
-       Download and install the Android NDK from the [official Android developer site](https://developer.android.com/ndk/downloads).
-
-Setup OpenCL Dependencies for NDK:
-
-You need to provide OpenCL headers and the ICD loader library to your NDK sysroot.
-
-*   OpenCL Headers:
-    ```bash
-    # In a temporary working directory
-    git clone https://github.com/KhronosGroup/OpenCL-Headers
-    cd OpenCL-Headers
-    # Replace <YOUR_NDK_PATH> with your actual NDK installation path
-    # e.g., cp -r CL /path/to/android-ndk-r26c/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include
-    sudo cp -r CL <YOUR_NDK_PATH>/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include
-    cd ..
-    ```
-
-*   OpenCL ICD Loader:
-    ```shell
-    # In the same temporary working directory
-    git clone https://github.com/KhronosGroup/OpenCL-ICD-Loader
-    cd OpenCL-ICD-Loader
-    mkdir build_ndk && cd build_ndk
-
-    # Replace <YOUR_NDK_PATH> in the CMAKE_TOOLCHAIN_FILE and OPENCL_ICD_LOADER_HEADERS_DIR
-    cmake .. -G Ninja -DCMAKE_BUILD_TYPE=Release \
-      -DCMAKE_TOOLCHAIN_FILE=<YOUR_NDK_PATH>/build/cmake/android.toolchain.cmake \

-      -DANDROID_PLATFORM=24 \
-      -DANDROID_STL=c++_shared
-
-    ninja
-    # Replace <YOUR_NDK_PATH>
-    # e.g., cp libOpenCL.so /path/to/android-ndk-r26c/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android
-    sudo cp libOpenCL.so <YOUR_NDK_PATH>/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android
-    cd ../..
-    ```
-
-Build `stable-diffusion.cpp` for Android with OpenCL:

-## Caching
-
-Caching methods accelerate diffusion inference by reusing intermediate computations when changes between steps are small.
-
-### Cache Modes
-
-| Mode | Target | Description |
-|------|--------|-------------|
-| `ucache` | UNET models | Condition-level caching with error tracking |
-| `easycache` | DiT models | Condition-level cache |
-| `dbcache` | DiT models | Block-level L1 residual threshold |
-| `taylorseer` | DiT models | Taylor series approximation |
-| `cache-dit` | DiT models | Combined DBCache + TaylorSeer |
-| `spectrum` | UNET models | Chebyshev + Taylor output forecasting |
-
-### UCache (UNET Models)
-
-UCache caches the residual difference (output - input) and reuses it when input changes are below threshold.
-
-```bash
-sd-cli -m model.safetensors -p "a cat" --cache-mode ucache --cache-option "threshold=1.5"
-```
-
-#### Parameters
-
-| Parameter | Description | Default |
-|-----------|-------------|---------|
-| `threshold` | Error threshold for reuse decision | 1.0 |
-| `start` | Start caching at this percent of steps | 0.15 |
-| `end` | Stop caching at this percent of steps | 0.95 |
-| `decay` | Error decay rate (0-1) | 1.0 |
-| `relative` | Scale threshold by output norm (0/1) | 1 |
-| `reset` | Reset error after computing (0/1) | 1 |
-
-#### Reset Parameter
-
-The `reset` parameter controls error accumulation behavior:
-
-- `reset=1` (default): Resets accumulated error after each computed step. More aggressive caching, works well with most samplers.
-- `reset=0`: Keeps error accumulated. More conservative, recommended for `euler_a` sampler.
-
-### EasyCache (DiT Models)
-
-Condition-level caching for DiT models. Caches and reuses outputs when input changes are below threshold.
-
-```bash
---cache-mode easycache --cache-option "threshold=0.3"
-```
-
-#### Parameters
-
-| Parameter | Description | Default |
-|-----------|-------------|---------|
-| `threshold` | Input change threshold for reuse | 0.2 |
-| `start` | Start caching at this percent of steps | 0.15 |
-| `end` | Stop caching at this percent of steps | 0.95 |
-
-### Cache-DIT (DiT Models)
-
-For DiT models like FLUX and QWEN, use block-level caching modes.
-
-#### DBCache
-
-Caches blocks based on L1 residual difference threshold:
-
-```bash
---cache-mode dbcache --cache-option "threshold=0.25,warmup=4"
-```
-
-#### TaylorSeer
-
-Uses Taylor series approximation to predict block outputs:
-
-```bash
---cache-mode taylorseer
-```
-
-#### Cache-DIT (Combined)
-
-Combines DBCache and TaylorSeer:
-
-```bash
---cache-mode cache-dit
-```
-
-#### Parameters
-
-| Parameter | Description | Default |
-|-----------|-------------|---------|
-| `Fn` | Front blocks to always compute | 8 |
-| `Bn` | Back blocks to always compute | 0 |
-| `threshold` | L1 residual difference threshold | 0.08 |
-| `warmup` | Steps before caching starts | 8 |
-
-#### SCM Options
-
-Steps Computation Mask controls which steps can be cached:
-
-```bash
---scm-mask "1,1,1,1,0,0,1,0,0,0,1,0,0,0,1,0,0,0,1,1"
-```
-
-Mask values: `1` = compute, `0` = can cache.
-
-| Policy | Description |
-|--------|-------------|
-| `dynamic` | Check threshold before caching |
-| `static` | Always cache on cacheable steps |
-
-```bash
---scm-policy dynamic
-```
-
-### Spectrum (UNET Models)
-
-Spectrum uses Chebyshev polynomial fitting blended with Taylor extrapolation to predict denoised outputs, skipping entire UNet forward passes. Based on the paper [Spectrum: Adaptive Spectral Feature Forecasting for Efficient Diffusion Sampling](https://github.com/tingyu215/Spectrum).
-
-```bash
-sd-cli -m model.safetensors -p "a cat" --cache-mode spectrum
-```
-
-#### Parameters
-
-| Parameter | Description | Default |
-|-----------|-------------|---------|
-| `w` | Chebyshev vs Taylor blend weight (0=Taylor, 1=Chebyshev) | 0.40 |
-| `m` | Chebyshev polynomial degree | 3 |
-| `lam` | Ridge regression regularization | 1.0 |
-| `window` | Initial window size (compute every N steps) | 2 |
-| `flex` | Window growth per computed step after warmup | 0.50 |
-| `warmup` | Steps to always compute before caching starts | 4 |
-| `stop` | Stop caching at this fraction of total steps | 0.9 |
-
-```
-
-### Performance Tips
-
-- Start with default thresholds and adjust based on output quality
-- Lower threshold = better quality, less speedup
-- Higher threshold = more speedup, potential quality loss
-- More steps generally means more caching opportunities

-# Running distilled models: SSD1B, Vega and SDx.x with tiny U-Nets
-
-## Preface 
-
-These models feature a reduced U-Net architecture. Unlike standard SDXL models, the SSD-1B and Vega U-Net contains only one middle block and fewer attention layers in its up- and down-blocks, resulting in significantly smaller file sizes. Using these models can reduce inference time by more than 33%. For more details, refer to Segmind's paper: https://arxiv.org/abs/2401.02677v1.
-Similarly, SD1.x- and SD2.x-style models with a tiny U-Net consist of only 6 U-Net blocks, leading to very small files and time savings of up to 50%. For more information, see the paper: https://arxiv.org/pdf/2305.15798.pdf.
-
-## SSD1B
-
-Note that not all of these models follow the standard parameter naming conventions. However, several useful SSD-1B models are available online, such as:
-
- * https://huggingface.co/segmind/SSD-1B/resolve/main/SSD-1B-A1111.safetensors
- * https://huggingface.co/hassenhamdi/SSD-1B-fp8_e4m3fn/resolve/main/SSD-1B_fp8_e4m3fn.safetensors
-
-Useful LoRAs are also available:
-
- * https://huggingface.co/seungminh/lora-swarovski-SSD-1B/resolve/main/pytorch_lora_weights.safetensors
- * https://huggingface.co/kylielee505/mylcmlorassd/resolve/main/pytorch_lora_weights.safetensors
-
-## Vega
-
-Segmind's Vega model is available online here:
-
- * https://huggingface.co/segmind/Segmind-Vega/resolve/main/segmind-vega.safetensors
- 
-VegaRT is an example for an LCM-LoRA:
-
- * https://huggingface.co/segmind/Segmind-VegaRT/resolve/main/pytorch_lora_weights.safetensors
-
-Both files can be used out-of-the-box, unlike the models described in next sections.
-
-
-## SD1.x, SD2.x with tiny U-Nets
-
-These models require conversion before use. You will need a Python script provided by the diffusers team, available on GitHub:
-
- * https://raw.githubusercontent.com/huggingface/diffusers/refs/heads/main/scripts/convert_diffusers_to_original_stable_diffusion.py
-
-### SD2.x
-
-NotaAI provides the following model online:
-
-* https://huggingface.co/nota-ai/bk-sdm-v2-tiny
-
-Creating a .safetensors file involves two steps. First, run this short Python script to download the model from Hugging Face:
-
-```python
-from diffusers import StableDiffusionPipeline
-pipe = StableDiffusionPipeline.from_pretrained("nota-ai/bk-sdm-v2-tiny",cache_dir="./")
-```
-
-Second, create the .safetensors file by running:
-
-```bash
-python convert_diffusers_to_original_stable_diffusion.py \
-      --model_path  models--nota-ai--bk-sdm-v2-tiny/snapshots/68277af553777858cd47e133f92e4db47321bc74 \
-      --checkpoint_path bk-sdm-v2-tiny.safetensors --half --use_safetensors
-```
-
-This will generate the **file bk-sdm-v2-tiny.safetensors**, which is now ready for use with sd.cpp.
-
-### SD1.x
-
-Several Tiny SD 1.x models are available online, such as:
-
- * https://huggingface.co/segmind/tiny-sd
- * https://huggingface.co/segmind/portrait-finetuned
- * https://huggingface.co/nota-ai/bk-sdm-tiny
-
-These models also require conversion, partly because some tensors are stored in a non-contiguous manner. To create a usable checkpoint file, follow these simple steps:
-Download and prepare the model using Python: 
-
-##### Download the model using Python on your computer, for example this way:
-
-```python
-import torch
-from diffusers import StableDiffusionPipeline
-pipe = StableDiffusionPipeline.from_pretrained("segmind/tiny-sd")
-unet=pipe.unet
-for param in unet.parameters():
-    param.data = param.data.contiguous()     # <- important here
-pipe.save_pretrained("segmindtiny-sd", safe_serialization=True)
-```
-
-##### Run the conversion script:
-
-```bash
-python convert_diffusers_to_original_stable_diffusion.py \
-      --model_path  ./segmindtiny-sd \
-      --checkpoint_path ./segmind_tiny-sd.ckpt --half
-```
-
-The file segmind_tiny-sd.ckpt will be generated and is now ready for use with sd.cpp. You can follow a similar process for the other models mentioned above.
-
-
-##### Another available .ckpt file:
-
- * https://huggingface.co/ClashSAN/small-sd/resolve/main/tinySDdistilled.ckpt
-
-To use this file, you must first adjust its non-contiguous tensors:
-
-```python
-import torch
-ckpt = torch.load("tinySDdistilled.ckpt", map_location=torch.device('cpu'))
-for key, value in ckpt['state_dict'].items():
-    if isinstance(value, torch.Tensor):
-        ckpt['state_dict'][key] = value.contiguous()
-torch.save(ckpt, "tinySDdistilled_fixed.ckpt")
-```
-
-
-### SDXS-512
-
-Another very tiny and **incredibly fast**  model is SDXS by IDKiro et al.  The authors refer to it as *"Real-Time One-Step Latent Diffusion Models with Image Conditions"*. For details read the paper: https://arxiv.org/pdf/2403.16627 . Once again the authors removed some more blocks of U-Net part and unlike other SD1 models they use an adjusted _AutoEncoderTiny_ instead of default _AutoEncoderKL_ for the VAE part.
-
-##### 1. Download the diffusers model from  Hugging Face using Python:
-
-```python
-from diffusers import StableDiffusionPipeline
-pipe = StableDiffusionPipeline.from_pretrained("IDKiro/sdxs-512-dreamshaper")
-pipe.save_pretrained(save_directory="sdxs")
-```
-##### 2. Create a safetensors file
-
-```bash
-python convert_diffusers_to_original_stable_diffusion.py \
-    --model_path  sdxs  --checkpoint_path sdxs.safetensors --half --use_safetensors
-```
-
-##### 3. Run the model as follows:
-
-```bash
-~/stable-diffusion.cpp/build/bin/sd-cli -m sdxs.safetensors -p "portrait of a lovely cat" \
-  --cfg-scale 1 --steps 1
-```
-
-Both options: ``` --cfg-scale 1 ``` and  ``` --steps 1 ``` are mandatory here.

-
-There are two ways to apply LoRA: **immediately** and **at_runtime**. You can specify it using the `--lora-apply-mode` parameter.
-
-By default, the mode is selected automatically:
-
-* If the model weights contain any quantized parameters, the **at_runtime** mode is used;
-* Otherwise, the **immediately** mode is used.
-
-The **immediately** mode may have precision and compatibility issues with quantized parameters, but it usually offers faster inference speed and, in some cases, lower memory usage.
-In contrast, the **at_runtime** mode provides better compatibility and higher precision, but inference may be slower and memory usage may be higher in some cases.

-Enabling flash attention for the diffusion model reduces memory usage by varying amounts of MB.

-For most backends, it slows things down, but for cuda it generally speeds it up too.
-At the moment, it is only supported for some models and some backends (like cpu, cuda/rocm, metal).

-
-sd.cpp also supports [TAEHV](https://github.com/madebyollin/taehv) (#937), which can be used for Qwen-Image and wan.
-
-- For **Qwen-Image and wan2.1 and wan2.2-A14B**, download the wan2.1 tae [safetensors weights](https://github.com/madebyollin/taehv/blob/main/safetensors/taew2_1.safetensors)
-  
-  Or curl
-  
-  ```bash
-  curl -L -O https://github.com/madebyollin/taehv/raw/refs/heads/main/safetensors/taew2_1.safetensors
-  ```
-
-- For **wan2.2-TI2V-5B**, use the wan2.2 tae [safetensors weights](https://github.com/madebyollin/taehv/blob/main/safetensors/taew2_2.safetensors)
-  
-  Or curl
-  
-  ```bash
-  curl -L -O https://github.com/madebyollin/taehv/raw/refs/heads/main/safetensors/taew2_2.safetensors
-  ```
-
-Then simply replace the `--vae xxx.safetensors` with `--tae xxx.safetensors` in the commands. If it still out of VRAM, add `--vae-conv-direct` to your command though might be slower.

-# Frontend
-
-## Build with Frontend
-
-The server can optionally build the web frontend and embed it into the binary as `gen_index_html.h`.
-
-### Requirements
-
-Install the following tools:
-
-* **Node.js** ≥ 22.18
-  https://nodejs.org/
-
-* **pnpm** ≥ 10
-  Install via npm:
-
-```bash
-npm install -g pnpm
-```
-
-Verify installation:
-
-```bash
-node -v
-pnpm -v
-```
-
-### Install frontend dependencies
-
-Go to the frontend directory and install dependencies:
-
-```bash
-cd examples/server/frontend
-pnpm install
-```
-
-### Build the server with CMake
-
-Enable the frontend build option when configuring CMake:
-
-```bash
-cmake -B build -DSD_SERVER_BUILD_FRONTEND=ON
-cmake --build build --config Release
-```
-
-If `pnpm` is available, the build system will automatically run:
-
-```
-pnpm run build
-pnpm run build:header
-```
-
-and embed the generated frontend into the server binary.
-
-## Frontend Repository
-
-The web frontend is maintained in a **separate repository**, https://github.com/leejet/stable-ui.
-
-If you want to modify the UI or frontend logic, please submit pull requests to the **frontend repository**.
-
-This repository (`stable-diffusion.cpp`) only vendors the frontend periodically. Changes from the frontend repo are synchronized:
-
-* approximately **every 1–2 weeks**, or
-* when there are **major frontend updates**
-
-Because of this, frontend changes will **not appear here immediately** after being merged upstream.
-
-## Using an external frontend
-
-By default, the server uses the **embedded frontend** generated during the build (`gen_index_html.h`).
-
-You can also serve a custom frontend file instead of the embedded one by using:
-
-```bash
---serve-html-path <path-to-index.html>
-```
-
-For example:
-
-```bash
-sd-server --serve-html-path ./index.html
-```
-
-In this case, the server will load and serve the specified `index.html` file instead of the embedded frontend. This is useful when:
-
-* developing or testing frontend changes
-* using a custom UI
-* avoiding rebuilding the binary after frontend modifications
-
-# Run
