How to Train Your AI Photo Model
Train your AI photo model by uploading 10-20 diverse, high-quality photos of yourself. Include varied angles, lighting, expressions and backgrounds. Training typically takes about 30 minutes, sometimes longer under load. The better your training photos, the better your generated results.

Training your AI model is the foundation of generating great AI photos. The quality and diversity of your training photos directly determine how realistic and versatile your generated photos will be. This guide covers everything you need to know about training your personal AI photo model.

What Is AI Model Training?
Understanding the process helps you get better results:
- The AI learns your facial features, proportions, and characteristics
- Training data = photos you upload to teach the AI what you look like
- The model learns to recreate you in new scenarios and settings
- Training happens once, then each new photo generates in seconds, within your plan's monthly photos
- Better training photos = more realistic and versatile results
- Process uses Flux LORA technology for high-quality generation
How Many Photos to Upload
The optimal number balances quality and variety:
- Minimum: 10 photos (bare minimum for decent results)
- Recommended: 15-20 photos (optimal balance)
- Stay within 10 to 20: past that, variety matters more than adding more photos
- More is not always better: quality and variety matter more than quantity
- Each photo should show something different (angle, lighting, expression)
What Makes a Good Training Photo
Your training photos should have these characteristics:
- High quality: Clear, in-focus, well-lit (no blurry or dark photos)
- Face clearly visible: The AI needs to see your features
- Variety of angles: Front, 3/4 angle, slight profile shots
- Different lighting: Natural light, indoor light, various times of day
- Various expressions: Smiling, serious, neutral, candid
- Multiple backgrounds: Indoor, outdoor, varied settings
- Different distances: Close-ups, medium shots, some full body
- Minimal obstructions: Avoid sunglasses, hats, hands covering face
Training Photos to Avoid
These types of photos will hurt your results:
- Blurry or out-of-focus images - AI can't learn from unclear features
- Heavily filtered or edited - Teaches AI wrong version of you
- Sunglasses or hats in most photos - AI needs to see your features
- Group photos - AI might get confused about which person is you
- Extreme angles or weird lighting - Makes training inconsistent
- Very old photos - Use recent photos (within 1-2 years)
- Low resolution or tiny file sizes - Insufficient detail for training
- Duplicate or near-duplicate photos - Wastes your photo slots
The Training Process
What to expect during model training:
- Upload 10-20 photos that meet the criteria above
- Training typically takes about 30 minutes, sometimes longer under load
- You'll receive notification when training is complete
- Once trained, you can generate photos immediately
- The model stays trained - no need to retrain for each photo
- You can train more than one model if your plan allows it (Starter includes one, Pro includes three)
After Training: Testing Your Model
Verify your model works well before generating lots of photos:
- Generate 3-5 test photos with different prompts
- Check if generated photos look like you
- Verify facial features are accurate (eyes, nose, mouth, face shape)
- Test different scenarios: formal, casual, indoor, outdoor
- If results are poor, retrain with better photos
- Save successful prompts to reuse later
- Iterate and improve your prompting skills
When to Retrain Your Model
You might want to retrain in these situations:
- Your appearance changes significantly (haircut, glasses, beard, etc.)
- Results don't look like you - training photos may have been poor
- You have better quality photos available now
- You want to try a different set of base photos
- After major weight change or other appearance changes
- Every 6-12 months to keep your model current
Conclusion
Training your AI model correctly is crucial for generating realistic, high-quality photos. Invest time in selecting 15-20 diverse, high-quality training photos that show your face clearly in various angles, lighting, and expressions. Avoid common mistakes like using filtered photos or images with obstructions. Once trained, test your model with various prompts and refine your approach. A well-trained model stays available while you are a subscriber and can generate photos of you in many different scenarios. You cannot add photos to a model after training, so the time you spend choosing a varied set pays off in every photo you generate.
