Soul ID trains a consistent AI character from at least 20 of your photos in about 3 minutes, per Higgsfield’s official FAQ (checked 4 Nov 2026). Once trained, the character is ready for unlimited generations across images and video — plan caps run from 1 generation on Free to 1,200 on Ultra.
Best for: creators who need the same face in every scene — Soul ID locks identity across styles, poses and lighting from 20+ photos in ~3 minutes (checked 4 Nov 2026), then generates unlimited images and video with that character.
Not for: one-off portrait experiments — training needs 20+ good photos and ~3 minutes, which is overkill for a single image you could make with a text prompt.
Starting price: Free covers 1 character generation (checked 4 Nov 2026); Starter at $19/month raises the cap to 108 generations.
What is Soul ID?
Soul ID is Higgsfield’s character-training feature: upload photos from multiple angles to train your character, then use the same consistent character across new images and videos (checked 4 Nov 2026). The identity stays locked across styles, poses and lighting — the same face in a fashion shoot, a cinematic still or a video clip.
It sits inside the Soul family alongside Soul 2.0 (the image model) and Soul Cinema (the cinematic model), and pairs with Soul HEX for color control. The official FAQ gives the headline numbers: a minimum of 20 photos, about 3 minutes of training, then unlimited generations with the trained character.
How to train a Soul ID: 7 steps
Each step notes its credit cost. Training itself is free — generations with the character are what count against caps and credits.
- Open Soul ID (Characters). Cost: 0 credits. Find the Characters section in the Higgsfield app — this is where trained identities live.
- Upload at least 20 photos from multiple angles. Cost: 0 credits. The official minimum is 20 photos; shots from different angles teach the model your face in three dimensions.
- Name your character. Cost: 0 credits. A clear name keeps multiple trained identities organized.
- Start training. Cost: 0 credits. One click begins the training run — about 3 minutes per the official FAQ.
- Wait for training to finish. Cost: 0 credits. You can leave the page; the trained Soul ID appears in your Characters when ready.
- Review the trained character. Cost: 0 credits. Generate a test image to confirm the likeness before committing to a project.
- Generate with your Soul ID. Cost: per generation — images via Soul 2.0 at 0.12 credits each (checked 4 Nov 2026), video at the chosen model’s rate; each generation counts against your plan’s character cap.
Soul ID generation caps by plan
Training is free, but generations with the character count against plan caps published on the pricing page (checked 4 Nov 2026). These are monthly allowances for character generations.
| Plan | Character generations/month (checked 4 Nov 2026) |
|---|---|
| Free | Up to 1 |
| Starter ($19/month) | Up to 108 |
| Plus ($59/month) | Up to 480 |
| Ultra ($129/month) | Up to 1,200 |
The cap counts generations that use the character — each image or video you make with your Soul ID uses one. Credits are deducted separately at the model’s normal rate, so a Soul ID video costs the same credits as a non-character video on the same model.
Using your Soul ID in images and video
Once trained, the character appears as a selectable identity across the Soul image models and video generation. The workflow is the same everywhere: pick the character, write the prompt, generate.
- Open the image or video generator. Cost: 0 credits. Soul ID works in Soul 2.0 images, Soul Cinema stills and video models.
- Select your trained character. Cost: 0 credits. The character picker shows your trained Soul IDs.
- Write the prompt with the scene, not the face. Cost: 0 credits. The identity is already locked — describe the setting, pose, outfit and lighting instead of facial features.
- Generate. Cost: 0.12 credits per Soul 2.0 image (checked 4 Nov 2026); video at the model’s published rate. Each generation counts against your plan’s character cap.
Pairing Soul ID with Soul Cinema is the standout combination: the official page confirms Soul Cinema works with Soul ID for character consistency, giving cinematic stills of the same face scene after scene (checked 4 Nov 2026).
Photo tips for a better Soul ID
- Multiple angles matter most. The official page asks for photos from multiple angles — front, three-quarter and profile teach the model the face in 3D.
- Use clear, well-lit photos. Blurry or dark uploads train a blurry character.
- Vary expressions slightly. Neutral plus a natural smile gives the model range without confusing it.
- Skip sunglasses, hats and heavy filters. Anything that hides the face hides it from the training too.
- Upload more than the minimum. 20 is the floor; 30–40 good photos train a more reliable likeness.
Credit costs for the Soul ID workflow
| Item | Cost (checked 4 Nov 2026) |
|---|---|
| Training a Soul ID | 0 credits (~3 minutes) |
| Soul 2.0 image with character | 0.12 credits |
| Kling 3.0 video with character (5s, 720p) | ~7 credits |
| Free Soul V2/Cinema gens (Starter/Plus/Ultra) | 300 / 5,000 / 10,000 per month |

Pros
- Training is free and takes ~3 minutes from just 20+ photos.
- Identity stays locked across styles, poses and lighting — the core promise, officially documented.
- Works across images and video, including Soul Cinema for cinematic stills.
- Unlimited generations once trained, within generous plan caps (up to 1,200 on Ultra).
Cons
- Free plan allows only 1 character generation — real use needs a paid plan.
- Needs 20+ good photos; a thin or low-quality photo set trains a weak likeness.
- Character caps (108/480/1,200) can bind heavy video users even on paid plans.
- Credits are still deducted per generation on top of the character cap.
- Training quality depends entirely on your uploads — garbage in, garbage out.
Who should NOT train a Soul ID
If you only need a character for one project with a handful of images, skip training — a descriptive text prompt in Soul 2.0 gets you close enough at 0.12 credits per image without the 20-photo homework. Soul ID pays off when the same face must recur across many generations.
Also skip it if you cannot supply 20+ clear photos. Training on a thin set produces an unreliable likeness, and every generation after that inherits the weakness.
Soul ID in a real project: a worked example
Take a concrete project: a 10-image fashion lookbook starring your Soul ID character. Training is free (~3 minutes from 20+ photos). Each Soul 2.0 image costs 0.12 credits (checked 4 Nov 2026), so 10 images cost 1.2 credits and use 10 character generations — well within Starter’s 108-generation cap. Add one 5-second Kling 3.0 intro clip (~7 credits, one more generation) and the whole project runs under 9 credits.
Scale that to video: a 4-scene product story with your character needs 4 video generations. On Kling 3.0 at 720p (~7 credits each), that is ~28 credits plus 4 character generations — still inside Starter’s monthly allowances of 270 credits and 108 character generations. The character cap, not the credit balance, is the tighter constraint for image-heavy Soul ID work; for video-heavy work, credits bind first.
Frequently asked questions
How many photos do I need to train a Soul ID?
A minimum of 20 photos, per Higgsfield’s official FAQ (checked 4 Nov 2026). Upload from multiple angles for the best likeness; 30–40 good photos train a more reliable character than the bare minimum.
How long does Soul ID training take?
About 3 minutes, per the official FAQ (checked 4 Nov 2026). Training is free — you only spend credits and character-cap generations when you start generating with the trained character.
Is Soul ID free?
Training is free, but generations with the character count against plan caps: up to 1 on Free, 108 on Starter, 480 on Plus and 1,200 on Ultra per month (checked 4 Nov 2026). Credits are deducted separately at each model’s normal rate.
Can I use my Soul ID in videos?
Yes. The official page states the trained character works across new images and videos (checked 4 Nov 2026). Select the character in the video generator and describe the scene — video generations bill at the chosen model’s credit rate and count against the character cap.
Does Soul ID work with Soul Cinema?
Yes. The Soul Cinema page confirms it works with Soul ID for character consistency (checked 4 Nov 2026) — cinematic stills of the same face, scene after scene, with Soul HEX available for color control.
What happens to my Soul ID if I cancel?
Per the official account-deletion help article, deleting your account permanently removes trained Soul characters along with all generations and settings (checked 4 Nov 2026). Download anything you need before deleting; merely cancelling a subscription keeps the account and its characters.
