- `benchmark-openvino.bat` - To benchmark OpenVINO
Alternatively you can run benchmarks by passing `-b` command line argument in CLI mode.
## OpenVINO support
Fast SD CPU utilizes [OpenVINO](https://www.intel.com/content/www/us/en/developer/tools/openvino-toolkit/overview.html) to speed up the inference speed.
Thanks [deinferno](https://github.com/deinferno) for the OpenVINO model contribution.
We can get 2x speed improvement when using OpenVINO.
Thanks [Disty0](https://github.com/Disty0) for the conversion script.
### OpenVINO SDXL models
These are models converted to use directly use it with FastSD CPU. These models are compressed to int8 to reduce the file size (10GB to 4.4 GB) using [NNCF](https://github.com/openvinotoolkit/nncf)
- Hyper-SD SDXL 1 step - [rupeshs/hyper-sd-sdxl-1-step-openvino-int8](https://huggingface.co/rupeshs/hyper-sd-sdxl-1-step-openvino-int8)
- SDXL Lightning 2 steps - [rupeshs/SDXL-Lightning-2steps-openvino-int8](https://huggingface.co/rupeshs/SDXL-Lightning-2steps-openvino-int8)
### OpenVINO SD Turbo models
We have converted SD/SDXL Turbo models to OpenVINO for fast inference on CPU. These models are intended for research purpose only. Also we converted TAESDXL MODEL to OpenVINO and
- *SD Turbo OpenVINO* - [rupeshs/sd-turbo-openvino](https://huggingface.co/rupeshs/sd-turbo-openvino)
- *SDXL Turbo OpenVINO int8* - [rupeshs/sdxl-turbo-openvino-int8](https://huggingface.co/rupeshs/sdxl-turbo-openvino-int8)
- *TAESDXL OpenVINO* - [rupeshs/taesdxl-openvino](https://huggingface.co/rupeshs/taesdxl-openvino)
You can directly use these models in FastSD CPU.
### Convert SD 1.5 models to OpenVINO LCM-LoRA fused models
We first creates LCM-LoRA baked in model,replaces the scheduler with LCM and then converts it into OpenVINO model. For more details check [LCM OpenVINO Converter](https://github.com/rupeshs/lcm-openvino-converter), you can use this tools to convert any StableDiffusion 1.5 fine tuned models to OpenVINO.
## Intel AI PC support - OpenVINO (CPU, GPU, NPU)
Fast SD now supports AI PC with Intel® Core™ Ultra Processors. [To learn more about AI PC and OpenVINO](https://nolowiz.com/ai-pc-and-openvino-quick-and-simple-guide/).
### GPU
For GPU mode `set device=GPU` and run webui. FastSD GPU benchmark on AI PC as shown below.
### NPU
FastSD CPU now supports power efficient NPU (Neural Processing Unit) that comes with Intel Core Ultra processors.
Please note that NPU support is experimental currently support [rupeshs/sd15-lcm-square-openvino-int8](https://huggingface.co/rupeshs/sd15-lcm-square-openvino-int8).
Supports following modes on NPU :
- Text to image
- Image to image
- Image variations
To run model in NPU follow these steps (Please make sure that your AI PC's NPU driver is the latest):
- Start webui
- Select LCM-OpenVINO mode
- Select the models settings tab and select OpenVINO model `sd15-lcm-square-openvino-int8`
- Now it will run on the NPU
This is heterogeneous computing since text encoder and Unet will use NPU and VAE will use GPU for processing. Thanks to OpenVINO.
Please note that tiny auto encoder will not work in NPU mode.
## GGUF support - Flux
[GGUF](https://github.com/ggerganov/ggml/blob/master/docs/gguf.md) Flux model supported via [stablediffusion.cpp](https://github.com/leejet/stable-diffusion.cpp) shared library. Currently Flux Schenell model supported.
To use GGUF model use web UI and select GGUF mode.

- Select the models settings tab and select GGUF diffusion,clip_l,t5xxl and VAE models.
- Enter your prompt and generate image
### Build stablediffusion.cpp shared library for GGUF flux model support(Optional)
To build the stablediffusion.cpp library follow these steps
- `git clone https://github.com/leejet/stable-diffusion.cpp`

Watch YouTube video :
[](https://www.youtube.com/watch?v=0XMiLc_vsyI)
## Models
To use single file [Safetensors](https://huggingface.co/docs/safetensors/en/index) SD 1.5 models(Civit AI) follow this [YouTube tutorial](https://www.youtube.com/watch?v=zZTfUZnXJVk). Use LCM-LoRA Mode for single file safetensors.
Fast SD supports LCM models and LCM-LoRA models.
### LCM Models
These models can be configured in `configs/lcm-models.txt` file.
### OpenVINO models
These are LCM-LoRA baked in models. These models can be configured in `configs/openvino-lcm-models.txt` file
### LCM-LoRA models
These models can be configured in `configs/lcm-lora-models.txt` file.
- *lcm-lora-sdv1-5* - distilled consistency adapter for [runwayml/stable-diffusion-v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5)
- *lcm-lora-sdxl* - Distilled consistency adapter for [stable-diffusion-xl-base-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0)
- *lcm-lora-ssd-1b* - Distilled consistency adapter for [segmind/SSD-1B](https://huggingface.co/segmind/SSD-1B)
These models are used with Stablediffusion base models `configs/stable-diffusion-models.txt`.
:exclamation: Currently no support for OpenVINO LCM-LoRA models.
### How to add new LCM-LoRA models
To add new model follow the steps:
For example we will add `wavymulder/collage-diffusion`, you can give Stable diffusion 1.5 Or SDXL,SSD-1B fine tuned models.
1. Open `configs/stable-diffusion-models.txt` file in text editor.
2. Add the model ID `wavymulder/collage-diffusion` or locally cloned path.
Updated file as shown below :
```Lykon/dreamshaper-8
Fictiverse/Stable_Diffusion_PaperCut_Model
stabilityai/stable-diffusion-xl-base-1.0
runwayml/stable-diffusion-v1-5
segmind/SSD-1B
stablediffusionapi/anything-v5
wavymulder/collage-diffusion
```
Similarly we can update `configs/lcm-lora-models.txt` file with lcm-lora ID.
### How to use LCM-LoRA models offline
Please follow the steps to run LCM-LoRA models offline :
- In the settings ensure that "Use locally cached model" setting is ticked.
- Download the model for example `latent-consistency/lcm-lora-sdv1-5`
Run the following commands:
```
git lfs install
git clone https://huggingface.co/latent-consistency/lcm-lora-sdv1-5
```
Copy the cloned model folder path for example "D:\demo\lcm-lora-sdv1-5" and update the `configs/lcm-lora-models.txt` file as shown below :
```
D:\demo\lcm-lora-sdv1-5
latent-consistency/lcm-lora-sdxl
latent-consistency/lcm-lora-ssd-1b
```
- Open the app and select the newly added local folder in the combo box menu.
- That's all!
## How to use Lora models
Place your lora models in "lora_models" folder. Use LCM or LCM-Lora mode.
You can download lora model (.safetensors/Safetensor) from [Civitai](https://civitai.com/) or [Hugging Face](https://huggingface.co/)
E.g: [cutecartoonredmond](https://civitai.com/models/207984/cutecartoonredmond-15v-cute-cartoon-lora-for-liberteredmond-sd-15?modelVersionId=234192)
## ControlNet support
We can use ControlNet in LCM-LoRA mode.
Download ControlNet models from [ControlNet-v1-1](https://huggingface.co/comfyanonymous/ControlNet-v1-1_fp16_safetensors/tree/main).Download and place controlnet models in "controlnet_models" folder.
Use the medium size models (723 MB)(For example : )

or use `start-webserver.sh` for Linux and `start-webserver.bat` for Windows.
Access API documentation locally at .
Generated image is JPEG image encoded as base64 string.
In the image-to-image mode input image should be encoded as base64 string.
