# Phoenix-4.5 Preview and Status

> How status and finetune_status work while a Phoenix-4.5 face goes from zero-shot preview to tuned.

Phoenix-4.5 has two stages from one [Create Face](/api-reference/faces/create-face) call. The face ID does not change.

1. A **zero-shot preview** becomes usable early (about a minute from a photo, minutes from video). That preview has a visible watermark burned into the video.
2. **Tuning** continues in the background for a few hours. When it finishes, the same face is the unwatermarked tuned version.

Poll [Get Face](/api-reference/faces/get-face). `status` answers “can I use this face?” `finetune_status` answers “did background tuning finish?”

This page is for **Phoenix-4.5**. Phoenix-4 and Phoenix-3 have no preview stage. Wait for `status` `completed`; `finetune_status` stays unused.

| Stage                   | `status`    | `finetune_status` | What you can do                                                             |
| ----------------------- | ----------- | ----------------- | --------------------------------------------------------------------------- |
| Training started        | `started`   | `null`            | Wait. The face is not usable yet.                                           |
| Zero-shot preview ready | `completed` | `started`         | Use the face. Output still has the preview watermark. Tuning is running.    |
| Tuning finished         | `completed` | `completed`       | Use the face. No preview watermark.                                         |
| Tuning failed           | `completed` | `errored`         | You can keep using the preview. Output shows a **tuning failed** watermark. |

`status` `error` still means the **create / preview** job failed. That face is not usable. That is different from `finetune_status` `errored`, where the preview already succeeded.

<Note>
  `status` `completed` on Phoenix-4.5 means the preview is ready, not that tuning is done. If you need the unwatermarked version, keep polling until `finetune_status` is `completed`.
</Note>

Optional: set `callback_url` on Create Face to get notified as these values change.

## If tuning errors

The preview stays available. Conversations and other uses of that `face_id` still work. The watermark changes to **tuning failed** so it is obvious the upgrade did not finish.

You do not submit the photo or video again. The face ID stays the same. If you need a new attempt, create a new face.

Phoenix-4 does not have this path. Its `status` `completed` means the whole job finished.
