Character consistency is a system problem, not a magic prompt. A model can create an excellent portrait and still change facial geometry, age, hairline, or wardrobe details in the next scene. Production workflows reduce that drift by controlling the source identity, choosing the least destructive operation, and reviewing images before video generation.

## The Consistency Ladder

Use the lightest method that satisfies the job:

1. **Prompt continuity** for loose visual themes where exact identity does not matter.
2. **Reference images** when a model should follow an approved visual subject.
3. **Image editing** when the subject is already right and only part of the scene should change.
4. **Trained identity or LoRA** when the same character must survive many unrelated scenes over time.

The mistake is jumping back to pure text generation for every campaign asset. Each fresh generation asks the model to reinvent the face.

## A Reliable API Architecture

Store these fields with every character:

- A stable internal character ID
- The MakeInfluencer `influencerId` when a trained identity exists
- One or more approved reference image URLs
- Preferred image-generation and editing model IDs
- Prompt invariants such as hair, age range, signature styling, and prohibited changes
- A set of approved outputs that can become future references

Your application can then choose a workflow based on the creative request rather than showing one generic “generate” button.

The [Qwen Image 2 Pro Edit API](/developers/models/qwen-image-2-pro-edit-api) accepts up to six reference images and is designed for precision edits. The [MakeInfluencer Flagship API](/developers/models/ai-influencer-image-api) is better suited to creator-focused generation with optional trained-character support.

## Prompt Invariants and Variables

Split prompts into two parts.

**Invariants** should rarely change:

- Identity and age presentation
- Hair length, texture, and color
- Distinctive facial or wardrobe details
- Brand-safe styling rules
- Product geometry that must remain accurate

**Variables** change per asset:

- Location and time of day
- Camera angle and framing
- Outfit within approved boundaries
- Activity and expression
- Aspect ratio and platform composition

This separation makes prompt templates maintainable. It also lets a campaign manager change the scene without accidentally removing identity constraints.

## Example: Controlled Outfit Edit

First inspect the live field contract:

```bash
curl https://www.makeinfluencer.ai/api/v1/models/qwen-image-2-pro-edit \
  --header "Authorization: Bearer $MAKEINFLUENCER_API_KEY"
```

Then preview an edit:

```bash
curl --request POST \
  https://www.makeinfluencer.ai/api/v1/models/qwen-image-2-pro-edit/preview-credits \
  --header "Authorization: Bearer $MAKEINFLUENCER_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "input": {
      "prompt": "Keep the same person, face, pose, and lighting. Replace the jacket with a cream linen blazer.",
      "imageUrls": ["https://example.com/approved-character.jpg"],
      "aspectRatio": "match_input_image"
    }
  }'
```

After approval, send the same input to `/generations` with an idempotency key.

<Callout type="warning" title="Do Not Promise Perfect Identity">
  Generative models are probabilistic. Build an approval step for commercial
  likeness, product accuracy, and brand details even when a trained identity or
  several references are used.

## Consistency Metrics That Matter

A production review can score five dimensions from 1 to 5:

| Dimension         | What to Check                                       |
| ----------------- | --------------------------------------------------- |
| Face              | Geometry, eyes, nose, jawline, and apparent age     |
| Hair              | Color, length, parting, and texture                 |
| Body              | Height impression, proportions, and recurring marks |
| Signature details | Accessories, tattoos, makeup, or brand identifiers  |
| Product fidelity  | Logos, package shape, text, and color               |

Rejecting a weak image before video generation saves more than the image credits: it prevents spending on animation, voice, editing, and review around a flawed source.

## Character Consistent API FAQ

### Is a reference image enough for perfect consistency?

No. It improves alignment but does not eliminate variation. A trained identity plus controlled editing and human approval gives a stronger long-term workflow.

### Which API is best for small changes?

Use an editing model such as [Qwen Image 2 Pro Edit](/developers/models/qwen-image-2-pro-edit-api). Editing preserves more of an approved frame than starting over.

### Can I animate the approved image?

Yes. Send the selected output into a compatible [image-to-video model](/guides/ai-image-to-video-api-for-influencers) or the [InfiniteTalk lip-sync API](/developers/models/infinitetalk-api).

### Does consistency require separate API billing?

No. All supported image and video models use the same MakeInfluencer credit balance across dashboard, REST, and MCP.
