# Bokeh 3.5 Medium
<div align="center">
<img src="ad2.jpg" alt="00205_" width="620"/>
</div>
Bokeh 3.5 Medium is a **Continue-training** model built upon the **stable diffusion 3.5 medium** foundation, further refined using a **500W high-resolution open-source dataset** with rigorous **aesthetic curation**. This ensures outstanding image quality, fine detail preservation, and enhanced controllability.
This model is released under the Stability Community License.
For more details, visit [Tensor.Art](https://tensor.art) or [TusiArt](https://tusiart.com) to explore additional resources and useful information.
## Overview
- **Continue-training on SD3.5M**, leveraging a large-scale **500W high-resolution dataset**, carefully curated for aesthetic quality.
- **Supports hybrid short/long caption training** for enhanced natural language understanding.
- **Short Captions:** Focus on core image features.
- **Long Captions:** Provide broader scene context and atmospheric details.
- **Recommended Resolutions:**
`1920x1024`, `1728x1152`, `1152x1728`, `1280x1664`, `1440x1440`
- **Best Quality Training Resolution:** `1440x1440`
- **Supports LoRA fine-tuning.**
## Advantages
### 🖼️ High-Quality Image Generation
- **State-of-the-art visual fidelity** with improved detail extraction and **aesthetic consistency**.
- **Enhanced resolution support** up to **200W pixels**, ensuring highly detailed image outputs.
- **Carefully curated dataset** ensures better composition, lighting, and overall artistic appeal.
### 🎯 Powerful Custom Fine-Tuning
- **Exceptional LoRA training support**, making it highly effective for:
- Photography
- 3D Rendering
- Illustration
- Concept Art
### ⚡ Efficient Inference & Training
- **Low hardware requirements for inference:**
- **Medium model:** 9GB VRAM (without T5)
- **Full weights inference:** 16GB VRAM (suitable for local deployment)
- **LoRA fine-tuning VRAM requirement:** 12GB - 32GB
## Known Issues
- **Potential human anatomy inconsistencies.**
- **Limited ability to generate photorealistic images.**
- **Some concepts may suffer from aesthetic quality issues.**
## Prompting Guide
### Use a structured prompt combining:
- **Main subject** (e.g., `"Close-up of a macaw"`)
- **Detailed features** (e.g., `"vivid feathers, sharp beak"`)
- **Background environment** (e.g., `"dimly lit environment"`)
- **Atmospheric description** (e.g., `"soft warm lighting, cinematic mood"`)
### Best Practices:
- **Avoid overly complex prompts**, as the model already has strong text encoding. Overloading details can cause **T5 hallucination artifacts**, reducing image quality.
- **Do not use excessively short prompts** (e.g., single words or 2-3 tokens) unless combined with **LoRA or Image2Image (i2i)** techniques.
- **Avoid mixing too many unrelated concepts**, as this can lead to visual distortions and unwanted artifacts.
- **Optimal token length:** **30-70 tokens**.
### Negative Prompting
- **Negative prompts strongly influence image quality.**
- Ensure they **do not contradict the main subject** to avoid degrading the output.
## Example Output
Using diffusers：
```python
import torch
from diffusers import StableDiffusion3Pipeline
pipe = StableDiffusion3Pipeline.from_pretrained("/mnt/share/pcm_outputs/bokeh_3.5_medium", torch_dtype=torch.bfloat16)
pipe = pipe.to("cuda")
image = pipe(
"Close-up of a macaw, dimly lit environment",
num_inference_steps=28,
guidance_scale=4,
height=1920,
width=1024,
).images[0]
image.save("macaw.jpg")
```
