# Phoenix-4.5 Image Requirements

> Photo rules for training a Phoenix-4.5 face from an image.

Use this path when you call [Create Face](/api-reference/faces/create-face) with **`model_name`: `phoenix-4.5`** and **`train_image_url`**. The image must be at a **publicly accessible URL** (for example a presigned S3 GET URL). You also [attach a voice](#voice).

See [Choose a Model and Training Path](/sections/faces/which-training-path) if you are still deciding. For Phoenix-4 photos, see [Phoenix-4 Image Requirements](/sections/faces/phoenix-4-image-requirements).

<Tip>
  We recommend using the [PAL Maker](https://maker.tavus.io/dev/faces/create) to upload an image. It runs the same checks the API uses, with real-time validation before training.
</Tip>

A zero-shot preview becomes usable in about a minute. The preview carries a visible watermark burned into the video. Tuning continues in the background for a few hours; the later tuned version does not carry the watermark.

  Image requirements
</h2>

Phoenix-4.5 works best as a **chest-up portrait**: mid-chest to just above the head, subject roughly centered with a little headroom, both shoulders in frame. Slightly wider (**waist-up**) or slightly closer both work. The face must stay fully visible and unobstructed. **Full body is not supported** on Phoenix-4.5; use [Phoenix-4](/sections/faces/phoenix-4-image-requirements) for head-to-toe.

* **Formats:** JPG or PNG
* **Minimum resolution:** 512×512 pixels
* **Only one person** visible in the image
* **Subject is an adult** (18+)
* **Human-shaped subject:** realistic, cartoon, anime, and Pixar-style faces are all fine. Animals, mascots, and other non-human figures are not
* **Head fully in frame**, subject centered, looking straight at the camera
* **Upright, neutral pose** (not leaning, lying down, or mid-gesture)
* **Face not blocked** by hands, phones, masks, or heavy hair over the eyes and nose
* **Even lighting** with minimal shadows across the face
* **Not** a household-name public figure or an obvious copyrighted character
* Do **not** send full-body, head-to-toe shots
* Keep arms relaxed and lowered, mostly out of frame (no raised or prominent arms)
* Glasses, jewelry, headphones, and hair in front of the shoulders are **allowed** as long as they do not cover the face. Shorter, crisp beards that leave the mouth and teeth visible work best - results may vary with dense or long beards.

<h2 id="voice">
  Attach a voice
</h2>

A photo has no audio, so nothing gets cloned the way it does on the video path. Send a voice on the same [Create Face](/api-reference/faces/create-face) request - a stock voice or one you train yourself. See [Voices for Image-Based Faces](/sections/faces/voices-for-image-based-faces).

<h2 id="ai-image-fixer">
  AI Image Fixer
</h2>

If your uploaded image doesn't fully meet these requirements, set **`auto_fix_training_image`** to `true` when calling [Create Face](/api-reference/faces/create-face). Tavus's AI Image Fixer adjusts the uploaded image to fit. Some policy failures (for example under-18 or copyrighted characters) cannot be auto-fixed.

```json theme={null}
{
  "face_name": "my_image_replica",
  "model_name": "phoenix-4.5",
  "train_image_url": "https://example.com/headshot.png",
  "auto_fix_training_image": true
}
```
