# LanPaint (Thinking mode Inpaint)
<div align="center">
Unlock precise inpainting without additional training. LanPaint lets the model "think" through multiple iterations before denoising, aiming for seamless and accurate results. We encourage you to try it out and share your feedback through issues or discussions, as your input will help us enhance the algorithm's performance and stability.

## Video Examples (Beta)
LanPaint now supports video inpainting with Wan 2.2, enabling you to seamlessly inpaint masked regions across video frames while maintaining temporal consistency.
**Note:** LanPaint supports video inpainting for longer sequences (e.g., 81 frames), but processing time increases significantly (please check the [Resource Consumption](#resource-consumption) section for details) and performance may become unstable. For optimal results and stability, we recommend limiting video inpainting to **40 frames or fewer**.
### Wan 2.2 Video Inpainting
*Example: Wan2.2 t2v 14B, 480p video (11:6), 40 frames, LanPaint K Sampler, 2 steps of thinking*

### Example Wan2.2: Partial InPaint(LanPaint K Sampler, 5 steps of thinking)
Sometimes we don't want to inpaint completely new content, but rather let the inpainted image reference the original image. One option to achieve this is to inpaint with an edit model like Qwen Image Edit. Another option is to perform a partial inpaint: allowing the diffusion process to start at some middle steps rather than from 0.

(Tricks 1: You can emphasize the character by copy it's image multiple times with Photoshop. Here I have made one extra copy.)
(Tricks 2: Use prompts like multiple views, multiple angles, clone, turnaround. Use LanPaint's Prompt first mode (does not support Flux))
(Tricks 3: Remeber LanPaint can in-paint: Mask non-consistent regions and try again!)

## Usage
**Workflow Setup**
@@ -71,53 +320,116 @@ Same as default ComfyUI KSampler - simply replace with LanPaint KSampler nodes.
- LanPaint requires binary masks (values of 0 or 1) without opacity or smoothing. To ensure compatibility, set the mask's **opacity and hardness to maximum** in your mask editor. During inpainting, any mask with smoothing or gradients will automatically be converted to a binary mask.
- LanPaint relies heavily on your text prompts to guide inpainting - explicitly describe the content you want generated in the masked area. If results show artifacts or mismatched elements, counteract them with targeted negative prompts.
### Basic Sampler
## Basic Sampler
![Samplers](https://github.com/scraed/LanPaint/blob/master/Nodes.JPG)
**LanPaint KSampler**
- LanPaint KSampler: The most basic and easy to use sampler for inpainting.
- LanPaint KSampler (Advanced): Full control of all parameters.
### LanPaint KSampler
Simplified interface with recommended defaults:
- Steps: 50+ recommended
- LanPaint NumSteps: 1-10 (complexity of edits)
- Built-in parameter presets
- Steps: 20 - 50. More steps will give more "thinking" and better results.
- LanPaint NumSteps: The turns of thinking before denoising. Recommend 5 for most of tasks ( which means 5 times slower than sampling without thinking). Use 10 for more challenging tasks.
- LanPaint Prompt mode: Image First mode and Prompt First mode. Image First mode focuses on the image, inpaint based on image context (maybe ignore prompt), while Prompt First mode focuses more on the prompt. Use Prompt First mode for tasks like character consistency. (Technically, it Prompt First mode change CFG scale to negative value in the BIG score to emphasis prompt, which will costs image quality.)
**LanPaint KSampler (Advanced)**
### LanPaint KSampler (Advanced)
Full parameter control:
## Key Parameters
**Key Parameters**
| Parameter | Range | Description |
|-----------|-------|-------------|
| `Steps` | 0-100 | Total steps of diffusion sampling. Higher means better inpainting. Recommend 50. |
| `LanPaint_NumSteps` | 0-20 | Reasoning iterations per denoising step ("thinking depth"). Easy task: 1-2. Hard task: 5-10 |
| `LanPaint_Lambda` | 0.1-50 | Content alignment strength (higher = stricter). Recommend 6.0 |
| `LanPaint_StepSize` | 0.1-1.0 | The StepSize of each thinking step. Recommend 0.1 for most cases, 0.5 for some difficult cases. |
| `LanPaint_cfg_BIG` | 0-20 | CFG scale used when aligning masked and unmasked region (higher = better alignment). Recommend 8 for seamless inpaint (i.e limbs, faces), 0-1 for character consistency (i.e multiple view) |
| `Steps` | 0-100 | Total steps of diffusion sampling. Higher means better inpainting. Recommend 20-50. |
| `LanPaint_NumSteps` | 0-20 | Reasoning iterations per denoising step ("thinking depth"). Easy task: 2-5. Hard task: 5-10 |
| `LanPaint_Lambda` | 0.1-50 | Content alignment strength (higher = stricter). Recommend 4.0 - 10.0 |
| `LanPaint_StepSize` | 0.1-1.0 | The StepSize of each thinking step. Recommend 0.1-0.5. |
| `LanPaint_Beta` | 0.1-2.0 | The StepSize ratio between masked / unmasked region. Small value can compensate high lambda values. Recommend 1.0 |
| `LanPaint_Friction` | 0.0-100.0 | The friction of Langevin dynamics. Higher means more slow but stable, lower means fast but unstable. Recommend 10.0 - 20.0|
| `LanPaint_EarlyStop` | 0-10 | Stop LanPaint iteration before the final sampling step. Helps to remove artifacts in some cases. Recommend 1-5|
| `LanPaint_PromptMode` | Image First / Prompt First | Image First mode focuses on the image context, maybe ignore prompt. Prompt First mode focuses more on the prompt. |

### LanPaint Mask Blend
This node blends the original image with the inpainted image based on the mask. It is useful if you want the unmasked region to match the original image pixel perfectly.
## LanPaint KSampler (Advanced) Tuning Guide
For challenging inpainting tasks:
1️⃣ **Primary Adjustments**:
- Increase **steps**, **LanPaint_StepSize**,**LanPaint_NumSteps** (thinking iterations), and **LanPaint_cfg_BIG** (guidance scale).
1️⃣ **Boost Quality**
Increase **total number of sampling steps** (very important!), **LanPaint_NumSteps** (thinking iterations) or **LanPaint_Lambda** if the inpainted result does not meet your expectations.
2️⃣ **Secondary Tweaks**:
- Boost **LanPaint_Lambda** (spatial constraint strength) or **LanPaint_StepSize** (denoising aggressiveness).
2️⃣ **Boost Speed**
Decrease **LanPaint_NumSteps** to accelerate generation! If you want better results but still need fewer steps, consider:
- **Increasing LanPaint_StepSize** to speed up the thinking process.
- **Decreasing LanPaint_Friction** to make the Langevin dynamics converges more faster.
3️⃣ **Balance Speed vs Stability**:
- Reduce **LanPaint_Friction** to prioritize faster results with fewer "thinking" steps (*may risk instability*).
- Increase **LanPaint_Tamed** (noise normalization onto a sphere) or **LanPaint_Alpha** (constraint the friction of underdamped Langevin dynamics) to suppress artifacts.
3️⃣ **Fix Unstability**:
If you find the results have wired texture, try
- Reduce **LanPaint_Friction** to make the Langevin dynamics more stable.
- Reduce **LanPaint_StepSize** to use smaller step size.
- Reduce **LanPaint_Beta** if you are using a high lambda value.
⚠️ **Notes**:
- Optimal parameters vary depending on the **model** and the **size of the inpainting area**.
- For effective tuning, **fix the seed** and adjust parameters incrementally while observing the results. This helps isolate the impact of each setting.
- For effective tuning, **fix the seed** and adjust parameters incrementally while observing the results. This helps isolate the impact of each setting. Better to do it with a batche of images to avoid overfitting on a single image.

His expression is calm, with a faint smile. Behind him: a dark, rain-washed cybercity backdrop—towering skyscrapers with flickering holographic ads, wet pavement reflecting neon pink/magenta lights. In front of him: giant, glowing white 3D text of \"LanPaint\", with electric blue energy pulses swirling around the equation. Cinematic lighting, hyper-detailed textures, rain droplets visible in the air."

"Cyberpunk-inspired portrait of a beautiful young woman with ethereal features: She has long, flowing silver hair with glowing purple neon streaks, wearing a form-fitting black leather jacket adorned with holographic circuit designs in electric blue, and augmented reality earrings that project faint digital fractals. Her eyes are piercing emerald green with subtle cybernetic enhancements showing data overlays, and her expression is mysterious yet alluring, with a subtle smirk. Behind her: a foggy, neon-lit futuristic alleyway—crumbling brick walls covered in vibrant graffiti and flickering LED signs, puddles on the ground reflecting turquoise and violet lights from overhead drones. Dramatic volumetric lighting, ultra-realistic details, mist particles in the air."
