Step-by-Step Guide: How to Train LoRA with AI Toolkit

Training a custom LoRA model with AI Toolkit is straightforward when you follow this comprehensive guide. This process will walk you through everything from dataset preparation to final model output, ensuring you get professional-quality results for your image generation projects.

Step 1: Upload Your Dataset

1. Create a New Dataset Folder

Begin by organizing your training data in the AI Toolkit interface. Navigate to the Datasets section and create a new folder for your project. This helps keep your training materials organized and easily accessible throughout the LoRA training process.

After creating the folder, rename it with a descriptive name that reflects your project's purpose. This naming convention will be helpful when managing multiple LoRA training projects simultaneously.

2. Import Your Training Images and Labels

Prepare your image dataset locally before uploading. Each image must have a corresponding text label file with an identical name. For example, if your image is named "portrait001.jpg", the label file should be "portrait001.txt". This precise naming convention is crucial for the AI Toolkit to properly associate images with their descriptions.

Ensure all images in your dataset have identical aspect ratios. This consistency is essential for effective LoRA training, as varying aspect ratios can lead to suboptimal results and training instability.

Upload both images and text labels simultaneously to maintain proper pairing. The platform will automatically detect and match corresponding files based on their names.

3. Verify Dataset Quality

After uploading sample images, preview your images and labels to ensure they match correctly. The interface allows you to edit image labels directly in the blue selection area if you notice any minor errors or need to make quick adjustments to improve training quality.

Step 2: Configure Your LoRA Project

4. Project Setup

Create a new training job by navigating to the New Job section. Choose a descriptive name for your model that reflects its intended purpose or style. If your system has multiple GPUs available, select the specific GPU you want to use for training to optimize resource allocation.

Add a trigger word if needed for your LoRA model. This trigger word should be unique and not overlap with your training name to avoid conflicts during generation.

5. Base Model Selection

Choose your desired checkpoint (base model) from the available options. AI Toolkit supports various foundation models including FLUX, WAN series, and others. The system will automatically populate the Hugging Face model path once you select a checkpoint, though you can manually specify custom paths if needed.

6. Quantization Settings

For most users, the default quantization settings work well. However, if you're using a GPU with less than 32GB of VRAM, change the setting from float8 to 6-bit quantization. This adjustment prevents memory issues and ensures stable training on consumer-grade hardware.

Higher quantization numbers require more GPU memory but can potentially improve training quality if your hardware supports it.

7. Linear Rank Configuration

The default Linear Rank value (32) works well for standard resolutions. If your dataset exceeds 1024x1024 resolution, reduce this value to 16. This optimization helps manage the computational load when working with FLUX-DEV's 120 billion parameters and improves training speed.

8. Save Configuration

Configure your save settings based on your needs. "Save Every 250" means the system will create a checkpoint every 250 training steps, while "Max Step Saves to Keep: 4" limits storage to the four most recent model versions to manage disk space efficiently.

Step 3: Training Parameters

9. Basic Settings

Set your batch size according to your GPU's VRAM capacity. Higher VRAM allows for larger batch sizes, which can improve training stability and speed. The trainer automatically enables multi-batch processing to enhance model generalization.

Adjust Gradient Accumulation for lower VRAM systems. Increasing gradient accumulation steps allows training on less powerful GPUs by trading training time for memory efficiency.

10. Algorithm Selection

Choose between Weighted (default, good for general use and learns image information chronologically) and Sigmoid (focuses on middle training steps, ideal for single-person portrait training) based on your specific project requirements.

Step 4: Dataset Configuration

11. Load Your Dataset

Select your previously uploaded dataset from the dropdown menu. If you need to combine multiple datasets, use the "Add Dataset" button to include additional training data sources.

12. Resolution Settings

Choose a resolution that closely matches your dataset's native resolution. Enable only one resolution option to maintain consistency throughout the training process.

Step 5: Sampling and Testing

13. Configure Sample Detection

Set up sampling parameters to monitor your model's progress during training. This feature creates preview generations that help you assess whether the training is proceeding as expected without affecting your labeled dataset.

14. Create Project Template

Finalize your configuration by clicking the "Create Job" button to create the project template. The system will automatically return you to the main interface, where you can monitor your training progress.

Step 6: Execute Training

15. Start Training Process

Click the execute button to start your LoRA training job using the configured parameters. The AI Toolkit will begin processing your dataset according to your specifications.

16. Monitor Progress

Keep track of your training through the log interface, which provides real-time updates on training progress, loss values, and any potential issues that might arise during the process.

17. Review Sample Outputs

During training, the system generates test samples at regular intervals. Review these preview images to assess the quality and direction of your LoRA training:

• Compare generated samples with your target style
• Identify any issues early in the training process
• Make adjustments if needed for future training runs

18. Save and Download Results

Once training completes successfully:

• Multiple checkpoint versions are automatically saved
• Download the LoRA model that best matches your requirements
• Each checkpoint shows file size and training step information
• Select the version that produces the most satisfactory results

This comprehensive approach to LoRA training with the AI Toolkit ensures you achieve consistent, high-quality results tailored to your specific creative vision and requirements.
