Quick Answer
To create consistent character AI images, use Midjourney's Character Reference feature (--cref) for the easiest workflow, or train a custom LoRA model in Leonardo AI/Stable Diffusion for professional-grade consistency. The --cref method allows you to lock in facial features across different scenes, while setting --cw 0 lets you change outfits while keeping the exact same face. For 100% control, LoRA training is the industry standard.
We’ve all been there. You generate a stunning AI character. The lighting is perfect, the expression is captivating, and the details are incredible. You decide to create a comic, a storybook, or a brand mascot with this character.
So, you generate the next scene. But wait... the nose is slightly different. The eye color shifted from hazel to green. The jawline is softer. It’s the same character concept, but it’s not the same character.
This is the "Consistency Problem," and it has been the biggest frustration for AI artists, comic creators, and brand designers since generative AI took off.
But here is the good news: The era of random, inconsistent AI faces is over.
In 2026, we have incredibly powerful tools and specific workflows designed to lock in your character's identity. Whether you want to use a simple parameter in Midjourney or train a dedicated neural network model, you can now achieve 95-99% facial consistency across hundreds of images.
In this comprehensive guide, I’ll show you exactly how to create consistent character AI images. I’ll break down the three best methods—from beginner-friendly tricks to professional workflows—complete with exact prompts, tool recommendations, and step-by-step instructions.

Why is AI Character Consistency So Hard?
Before we fix the problem, it helps to understand why it exists. AI image generators like Midjourney and Stable Diffusion don't actually "know" what a character is. They don't have a 3D model of your character stored in their memory.
🧠 The "Latent Space" Problem
• AI generates images by navigating a multi-dimensional "latent space" of concepts.
• When you type "cyberpunk woman," the AI rolls the dice and picks a random point in that space.
• Every time you hit generate, it rolls the dice again, resulting in a completely different face.
• Without an "anchor," the AI has no mathematical reason to generate the same nose, eyes, or jawline twice.
To fix this, we have to force the AI to use an "anchor." We do this through three main methods: Seed Locking, Character Referencing, and Model Training (LoRA).
The 3 Methods to Achieve Character Consistency
Depending on your skill level and the tools you have access to, here are the three proven ways to keep your characters consistent.
Method 1: Seed & Prompt Anchoring
Use the same seed number and hyper-specific text prompts. Free, works in any tool, but offers moderate consistency (70-80%).
Method 2: Character Reference (--cref)
Midjourney's game-changing feature. Upload an image, and the AI copies the face. Extremely easy, 90-95% consistency.
Method 3: LoRA Model Training
Train a custom AI model on 15-20 images of your character. Used in Stable Diffusion and Leonardo AI. 99% consistency.
Method 1: Seed & Prompt Anchoring (The Free Way)
If you don't want to pay for Midjourney or learn complex software, you can use the "Seed" method. Every AI image has a unique "seed number" (a random string of digits). If you use the same seed and the exact same prompt, the AI will generate a very similar image.
How to Use Seed Numbers
Generate Your Base Image
Create your character. Once you get an image you love, react to it with an envelope emoji (✉️) in Midjourney, or copy the seed number from the web interface of your tool.
Create a "Master Prompt"
Write a highly detailed, unchanging description of your character. Don't just say "a beautiful woman." Say: "A 25-year-old woman with a sharp jawline, heterochromia (one blue eye, one green eye), a small scar on her left cheek, and short platinum blonde pixie hair."
Apply the Seed
Add --seed 123456789 to the end of your prompt. Keep the Master Prompt exactly the same, only changing the background or pose.
⚠️ The Limitation: The seed method is great for keeping the vibe and basic features similar, but if you change the angle too much (e.g., from front profile to side profile), the face will start to morph. For true consistency across different angles, you need Method 2 or 3.
Method 2: Midjourney Character Reference (--cref) (The Best Way)
Midjourney v6 introduced the --cref (Character Reference) parameter, and it completely changed the game for AI comic artists and storytellers. This feature tells the AI: "Look at this specific image, and copy the facial features and clothing onto my new prompt."
Step-by-Step: Using --cref
Get Your Base Image URL
Generate the perfect portrait of your character. Right-click the upscaled image and select "Copy Image Address". This URL is your anchor.
Write Your New Scene Prompt
Describe the new scene you want. For example: "A cinematic shot of a woman sitting in a neon-lit cyberpunk cafe, raining outside, drinking coffee."
Add the --cref Parameter
At the very end of your prompt, add a space, then type --cref followed by a space, and paste your image URL.
/imagine prompt: A cinematic shot of a woman sitting in a neon-lit cyberpunk cafe, raining outside, drinking coffee --cref https://discord.com/attachments/your-image-url.png --cw 100
The Magic of --cw (Character Weight)
This is the secret sauce. The --cw parameter tells the AI what to copy from the reference image.
--cw 100(Default): Copies the face, hair, AND the outfit. Use this when you want the exact same character in the exact same clothes.--cw 0(Face Only): Copies ONLY the facial features. It ignores the hair and clothing. This is how you change your character's outfit while keeping the same face!--cw 50: A balance between face and outfit.
✅ Pro Tip: If you want to create a character sheet showing your character from the front, side, and back, use --cref [URL] --cw 100 and add "character design sheet, multiple views, front view, side view, back view, white background" to your prompt.
Method 3: LoRA Training (The Professional Way)
If you are creating a professional comic, a children's book, or a brand mascot, you need 100% consistency. You need LoRA (Low-Rank Adaptation) training.
A LoRA is a mini AI model trained specifically on your character. Once trained, you can plug it into Stable Diffusion or Leonardo AI, and the AI will "know" your character as well as it knows the concept of a "dog" or a "car".
How to Train a Character LoRA on Leonardo AI
Leonardo AI makes LoRA training incredibly easy for non-technical users.
- Generate 15-20 images of your character using Midjourney or another tool. Ensure the face is clearly visible in different lighting, angles, and expressions.
- Go to Leonardo AI and navigate to the "Training" tab.
- Create a New Model: Upload your 15-20 images. Name your model (e.g., "MyHero_Character").
- Set the Trigger Word: Choose a unique word that isn't a real word, like
ohwxmanorxyzwoman. - Train the Model: Hit train. It takes about 15-30 minutes.
Using Your LoRA
Once trained, you simply include your trigger word in any prompt on Leonardo AI or Stable Diffusion:
Prompt: ohwxwoman fighting a dragon in a snowy mountain, epic fantasy lighting, 8k resolution.
The AI will generate your exact character, with perfect consistency, in any pose, outfit, or scenario you can imagine.
If you're writing the lore and backstory for your newly consistent character, you'll need great writing skills. Learn how to write long-form AI blog posts that pass AI detection to create compelling, human-like stories for your characters.

How to Change Outfits While Keeping the Same Face
This is the most common question I get: "I love my character's face, but I need them to wear a spacesuit in one scene and a tuxedo in another. How do I do that without changing their face?"
Here is the exact workflow using Midjourney:
Use --cref with --cw 0
As mentioned earlier, --cw 0 tells Midjourney to ONLY look at the facial features in your reference image and ignore the clothing.
Describe the New Outfit in Detail
Since the AI is ignoring the old outfit, you must explicitly describe the new one in your text prompt.
/imagine prompt: A portrait of a woman wearing a futuristic white spacesuit with glowing blue accents, standing on Mars --cref [URL] --cw 0
💡 Why this works: By setting Character Weight to 0, you decouple the face from the style. The AI uses the reference image purely as a "face map" and uses your text prompt for everything else.
Common Mistakes & How to Fix Them
Even with the best tools, you might run into issues. Here’s how to troubleshoot the most common consistency problems:
✅ Problem: The face looks slightly different every time
- Fix: Your base reference image might be too stylized or have bad lighting. Use a clean, well-lit, front-facing portrait as your
--crefanchor. - Fix: Increase the
--cwvalue closer to 100 if it's set too low.
⚠️ Problem: The AI is copying the background from the reference
- Fix: This happens if your reference image has a busy background. Crop your reference image tightly around the face before using the URL.
- Fix: Use
--cw 0to force the AI to ignore everything except the face.
Real-World Use Cases for Consistent Characters
Why go through the trouble of making consistent characters? Because it unlocks entirely new business and creative opportunities:

Frequently Asked Questions
To create consistent character AI images, use Midjourney's Character Reference feature (--cref), train a custom LoRA model in Leonardo AI or Stable Diffusion, or use seed numbers with highly specific descriptive prompts. The --cref method is currently the easiest for beginners, while LoRA training offers the highest level of consistency for professional projects.
Midjourney v6 is currently the best tool for consistent characters using its --cref (character reference) parameter, which captures facial features and style effortlessly. For absolute control and commercial independence, Stable Diffusion with a custom-trained LoRA model is the industry standard for professional comic artists and animators.
In Midjourney, use the --cref parameter with your base character image URL, and set --cw 0 (character weight zero). This tells the AI to only reference the face and ignore the clothing in the reference image, allowing you to describe a completely new outfit in your text prompt while keeping the face identical.
Yes, you can create consistent AI characters for free using Leonardo.ai, which offers daily free credits and allows you to train custom models (LoRAs) on their platform. Alternatively, you can use Stable Diffusion locally on your PC if you have a good graphics card, which is 100% free and unlimited.
For a highly consistent character LoRA, you need 15 to 20 high-quality images. These should include different angles (front, side, 3/4 view), different expressions, and varied lighting. Avoid using images where the face is obscured by hair, hands, or objects. Quality is much more important than quantity.
Yes, if you are on a paid plan for Midjourney, Leonardo AI, or use local Stable Diffusion, you own the commercial rights to the images you generate. You can sell comics, merchandise, and digital assets featuring your consistent AI characters without any legal issues.
