Technical Deep-Dive: Advanced Techniques
LoRA Training for Character Consistency
Training Parameters Explained
Controls how fast the model learns. Too high = overfitting, too low = undertraining. Sweet spot: 1e-4 for most faces.
Number of images processed simultaneously. Higher = faster but more VRAM. Most use 2-3.
Full training passes through dataset. 15-20 epochs works for most character LoRAs.
LoRA complexity. Higher = more detail retention but larger file. 64 is standard.
Pro Tips for Perfect LoRA
- • Use 15-20 images minimum, 30 maximum (more isn't always better)
- • Include variety: different angles (front, 3/4, profile), expressions (smile, serious, surprised), lighting
- • Tag images properly: "1girl, brown hair, blue eyes, smiling, portrait" format
- • Save checkpoints every 5 epochs to compare quality progression
- • Test at multiple weights: 0.6 (subtle), 0.8 (balanced), 1.0 (strong)
Textual Inversion & Embeddings
Alternative to LoRA - teaches SD a new "word" that represents your character. Smaller file size but less powerful.
Advantages
- • Tiny file size (10-50KB vs 100-200MB LoRA)
- • Easy to share and distribute
- • Works with any checkpoint
- • Faster training (2-4 hours)
Limitations
- • Less consistent results than LoRA
- • Can't capture complex features well
- • Requires more prompt engineering
- • Lower accuracy (~80% vs 95% LoRA)

Learning Tips for Beginners
Frequently Asked Questions
Can I use both tools together?
Absolutely! The hybrid approach is actually recommended. Use Midjourney for initial character exploration and concept art, then Stable Diffusion with LoRA for production content. Many successful AI influencer creators use this exact workflow.
Which tool has better image quality?
Midjourney typically produces more artistic, visually stunning images out-of-the-box. Stable Diffusion can match or exceed MJ quality with proper checkpoint selection and settings, but requires more technical knowledge. For photorealistic AI influencers, SD is often better. For stylized/artistic influencers, MJ wins.
How long does it take to train a LoRA?
Training time depends on your GPU. With an RTX 4090, expect 30-60 minutes for a standard character LoRA (20 images, 15 epochs). With an RTX 3060, it might take 2-3 hours. Cloud services like RunPod can train a LoRA in under an hour for $0.50-1.00.
Can Midjourney create consistent characters without SD?
Midjourney's --cref (character reference) feature helps, but it's not as consistent as SD LoRA training. Expect 70-80% facial similarity with --cref vs 95%+ with LoRA. For serious AI influencers posting daily, the consistency difference is noticeable to audiences.
Do I need a powerful PC for Stable Diffusion?
Minimum: RTX 3060 12GB ($300-400 used). Recommended: RTX 4070 or better. Alternative: Use cloud services like RunPod ($0.34/hour) or Massed Compute ($0.29/hour) for pay-as-you-go access. You can run SD on a MacBook with M1/M2 chips but generation is slower.
Which tool is better for beginners?
Midjourney is far more beginner-friendly. You can start generating quality images in 30 minutes. Stable Diffusion has a steeper learning curve (2-4 weeks to proficiency) but offers more control long-term. If you're non-technical, start with MJ. If you're comfortable with software, dive straight into SD.
Can I sell images created with these tools?
Stable Diffusion: Yes, completely unrestricted commercial use. Midjourney: Yes on paid plans ($30+/month), with attribution required on free trial. Both allow monetization through sponsored posts, digital products, and subscriptions. Always verify current TOS as policies can change.
What's the break-even point for Stable Diffusion?
If generating 300+ images monthly, SD pays for itself in 2-3 months vs Midjourney Standard ($60/month). If generating 100 images monthly, break-even is 6-7 months. The ROI improves dramatically in years 2-3 when SD costs drop to near-zero (just electricity).
