## Model Description

**TensorArt-TurboX-SD3.5Large** is a highly optimized variant of **Stable Diffusion 3.5 Large**, achieving **6x faster generation speed** with minimal quality loss. It surpasses the official **Stable Diffusion 3.5 Large Turbo** in **image detail, diversity, richness, and realism**.

The model is available in both **LoRA** and **checkpoint (ckpt)** formats(chosen one of them, don't use them at same time), ensuring **compatibility with most community models**. This allows seamless integration into various workflows, accelerating **open-source AI development**.

## Key Features

- 🚀 **6x Speed Boost**: Generates images significantly **faster** than the original SD3.5 Large.
- 🎨 **Superior Quality**: Outperforms **stabilityai/stable-diffusion-3.5-large-turbo** in **detail, diversity, and realism**.
- 🔄 **Versatile Compatibility**: Works with both **realistic** and **anime-style** models.
- ⚡ **Optimized for Efficiency**: Suitable for both **high-end and mid-range GPUs**.

## Recommended Settings

For optimal results, we recommend using:

- **Sampler**: `Euler`
- **Scheduler**: `Simple`
- **Sampling Steps**: `8`
- **CFG Scale**: `1.0 - 1.5` _(Note: CFG ≠ 1 will double generation time)_
- **Shift**: `5` _(Most important！！！)_
- **LoRA Strength**: `1.0` _(if using LoRA version)_
## Example Comparisons

### TensorArt-TurboX-SD3.5Large vs. Official Models

Here are some sample outputs comparing **TensorArt-TurboX-SD3.5Large** (8 steps, CFG=1, Simple scheduler) with **official stable-diffusion-3.5-large-turbo** when using the same time. The contrast workflow are here: [constrast_normal_TurboX](./contrast_sd3.5L_normal_TurboX.json), [contrast_TurboX_turbo](./contrast_sd3.5L_TurboX_turbo_diff_cfg.json):

## Example Output
   Using ckpt： 

   ```python
    import torch
    from diffusers import StableDiffusion3Pipeline

    repo = "tensorart/stable-diffusion-3.5-large-TurboX"


    pipe = StableDiffusion3Pipeline.from_pretrained(repo, torch_dtype=torch.float16)
                                                    
    pipe = pipe.to("cuda")


    generator = torch.Generator(device="cuda").manual_seed(1)

    image = pipe(
    "A beautiful bald girl with silver and white futuristic metal face jewelry, her full body made of intricately carved liquid glass in the style of Tadashi, the complexity master of cyberpunk, in the style of James Jean and Peter Mohrbacher. This concept design is trending on Artstation, with sharp focus, studio-quality photography, and highly detailed, intricate details.",
    num_inference_steps=8,
    guidance_scale=1.5,
    height=1024,
    width=768,
    generator=generator
    ).images[0]

    image.save("./test2-3.webp")

   ```

   Using lora：

   ```python
   import torch
   from diffusers import StableDiffusion3Pipeline, FlowMatchEulerDiscreteScheduler
   import numpy as np
   from safetensors.torch import load_file
   from huggingface_hub import hf_hub_download

   repo = "tensorart/stable-diffusion-3.5-large-TurboX"
   ckpt = "Tensorart_TurboX_sd3.5L_8steps.safetensors"

   pipe = StableDiffusion3Pipeline.from_pretrained("stabilityai/stable-diffusion-3.5-large", torch_dtype=torch.float16,)
                                                   
   pipe = pipe.to("cuda")
   pipe.load_lora_weights(hf_hub_download(repo, ckpt))
   pipe.fuse_lora()
   
   pipe.scheduler = FlowMatchEulerDiscreteScheduler.from_pretrained(repo, subfolder="scheduler", shift=5)

   generator = torch.Generator(device="cuda").manual_seed(1)
   image = pipe(
      "A beautiful bald girl with silver and white futuristic metal face jewelry, her full body made of intricately carved liquid glass in the style of Tadashi, the complexity master of cyberpunk, in the style of James Jean and Peter Mohrbacher.
