Quick answer: Higgsfield Soul ID trains a reusable character from your photos so the same face appears in every image and video. Upload 20 or more photos of the same person (up to 80) — different angles, expressions and lighting, plus at least one full-body shot — and training takes a few minutes. Then select your Soul ID when generating. Only train on yourself or people who have given clear consent.
What is Soul ID?
AI tools often change a person’s face between generations. Soul ID fixes this by learning one identity from reference photos, so you can create a recurring character for a series, a brand or a virtual influencer.
Photo checklist
| Do | Avoid |
|---|---|
| 20+ photos (up to 80) | Fewer than 20 photos |
| Different angles and expressions | The same pose repeated |
| Clear, well-lit faces | Sunglasses, heavy shadows, cropped faces |
| At least one full-height photo | Only close-ups |
| Recent photos (last few months) | Very old photos with a different look |
| Only one person per photo | Group shots |

How to create a Soul ID (step by step)
- Open the character / Soul ID section in Higgsfield.
- Upload 20–80 photos that meet the checklist.
- Name your character and start training (a few minutes).
- Generate a test image with a simple prompt.
- Check the likeness; add better photos and retrain if needed.
- Select your Soul ID in image or video tools for consistent results.
Where can you use your Soul ID?
Soul ID is designed for Higgsfield’s Soul image models (such as Soul 2.0) and can carry into supported video workflows. Higgsfield notes a trained character works in the model family it was trained for, so check compatibility in the tool you’re using.
Tips for consistent characters
- Describe the outfit and setting the same way across prompts.
- Create first frames with Soul ID, then animate them — see our image-to-video guide.
- Keep lighting and colour style consistent across a series.
- Use simple camera moves so faces don’t distort.
Soul ID vs a single reference image
| Soul ID | One reference image | |
|---|---|---|
| Setup | Train once on 20–80 photos | Upload one photo each time |
| Consistency | High across many generations | Lower, can drift |
| Prompt freedom | Full prompts with your character | On some Soul models, attaching a reference image hides the prompt field |
| Best for | Series, brands, influencers | Quick one-off edits |
Decide which mode you want before you start, so you don’t waste credits switching back and forth.
Which models work with Soul ID?
Soul ID is built for Higgsfield’s Soul image models, including Soul 2.0 and Soul Cinema. Some reviews report that a Soul ID image can then be animated with video models such as Kling, Veo or Seedance — the usual workflow is: create the image with Soul ID, then use it as the first frame of a video. Check the current options inside the tool on higgsfield.ai.
Example prompts with your Soul ID
- “[Your character] sitting in a sunny café, reading a book, soft window light, 35mm film look.”
- “[Your character] walking through a rainy neon street at night, wearing a black raincoat, cinematic.”
- “Close-up portrait of [your character] laughing, studio lighting, plain beige background.”
Fixing likeness problems
| Problem | Likely cause | Fix |
|---|---|---|
| Face looks like someone else | Too few or blurry photos | Add sharper, varied photos and retrain |
| Always the same expression | Photos show one expression | Add smiling, serious and side-view photos |
| Body shape is wrong | No full-body photos | Add 2–3 full-length photos |
| Face changes in video | Fast camera motion | Use a slow push-in or static shot |
Using Soul ID for a series or brand
- Create a character sheet: name, age, style, usual outfit and colour palette.
- Save 3–5 “master” prompts for your most common scenes.
- Generate first frames with Soul ID for each episode or post.
- Animate with gentle camera moves so the face stays stable — see our camera motions guide.
- Keep a log of prompts and settings that worked best.
Consent and safety
Only train Soul IDs on yourself or people who have given explicit, preferably written, permission. Never create a Soul ID of a celebrity or anyone without consent. Label realistic AI influencers as AI.
Example: building a photo set for Soul ID
Here is a simple shot list for collecting 25 strong training photos of one person:
| Photos | What to capture |
|---|---|
| 6 | Front-facing headshots with different expressions (neutral, smile, laugh, serious) |
| 6 | Three-quarter views from the left and right |
| 4 | Side profiles from both sides |
| 4 | Upper-body shots with different outfits |
| 3 | Full-body shots standing and walking |
| 2 | Outdoor daylight shots with natural backgrounds |
Use recent photos, keep the hairstyle consistent with how you want the character to look and avoid heavy filters or beauty apps, which change facial features.
Planning a content series with Soul ID
- Define the character: name, age, style and personality in one paragraph.
- Choose two or three recurring locations to keep the series recognisable.
- Write ten prompt ideas covering different outfits and situations.
- Generate in batches and keep only images that clearly look like the same person.
- Animate the best images with image to video. See our image to video guide.
- Review consistency every few posts and retrain if the identity drifts.
Soul ID for brands and businesses
Brands use Soul ID to create a recurring presenter or ambassador who appears across ads, social posts and product pages. If the character is based on a real person, such as a founder or employee, get written consent that covers how and where the likeness will be used and what happens if they leave the company. For invented characters, keep a style guide so every team member describes the character the same way.
How long does training take?
Training usually takes a short while after you upload your photos, depending on demand. Use that time to plan your first prompts. When training finishes, test the identity with five simple prompts (a studio portrait, an outdoor shot, a close-up, a side angle and a full-body image) before starting a real project. If two or more look off, improve the photo set and retrain.
