Training Process
-
Data Upload
Prepare and upload a ZIP file containing your training images. Include 10-20 high-quality, diverse images for best results.
-
Configure Trigger Word
Set a unique trigger word (e.g., "p3r5on") that will activate your trained style or character in prompts.
-
Adjust Training Parameters
- steps — Total training iterations (default: 1000)
- learning_rate — Training speed (default: 0.0001)
- lora_rank — Adapter capacity (default: 16)
-
LoRA Training
The system runs a tailored LoRA optimization loop:
- Freezes the base model weights
- Trains only the low-rank adapter layers
- Applies Z-Image optimized settings
-
Model Export
After training completes, you receive a LoRA adapter file (.safetensors) compatible with:
Parameters
| Parameter | Required | Default | Description |
|---|
| data | Yes | — | ZIP file containing training images (min 4 images recommended) |
| trigger_word | No | p3r5on | Unique word to activate your trained concept |
| steps | No | 1000 | Number of training steps (500-10000) |
| learning_rate | No | 0.0001 | Training speed (lower = more stable) |
| lora_rank | No | 16 | Adapter capacity (1-64, higher = more detail) |
How to Use
- Prepare your images — collect 10-20 high-quality, diverse images of your subject.
- Create a ZIP file — package all images into a single ZIP archive.
- Upload your data — drag and drop or provide a public URL to your ZIP file.
- Set trigger word — choose a unique word that won't conflict with common terms.
- Adjust parameters (optional) — modify steps, learning_rate, and lora_rank as needed.
- Run — submit and wait for training to complete.
- Download — receive your LoRA adapter file for use with Z-Image models.

Best Use Cases
- Character LoRAs — Train on character images to maintain identity across generations.
- Brand Styles — Create custom visual styles for consistent marketing imagery.
- Art Styles — Capture specific artistic aesthetics for creative projects.
- Product Photography — Train on product photos for consistent visual presentations.
Pro Tips
- Use 10-20 high-quality, diverse images of your subject for best results.
- Choose a unique trigger word that won't conflict with common words (e.g., "m1style" instead of "style").
- Higher lora_rank (32-64) captures more detail but increases training time and file size.
- Lower learning_rate (0.00005) is more stable but requires more steps.
- Start with default settings, then adjust if needed.
Try Your LoRA
After training, use your LoRA with these models:
- Z-Image Base LoRA — Base model with LoRA support.
- Z-Image Turbo LoRA — Fast generation with LoRA support.
Guidance
Notes
- Minimum recommended: 4 images, optimal: 10-20 images.
- Training time scales with the number of steps configured.
- Higher parameter values (steps, lora_rank) will increase training time and cost.
- For faster iterations, start with lower settings and increase gradually.
