# Training Center

> View the training queue items collected from all data sources and control training and cleanup.

## Purpose

<div className="t3-embed">
  <iframe src="https://app.supademo.com/embed/cmracqklk0e92qmhxeuqwubf8?utm_source=link" loading="lazy" title="T3AC Training Center Demo" allow="clipboard-write; fullscreen" frameBorder="0" webkitallowfullscreen="true" mozallowfullscreen="true" allowfullscreen />
</div>

View the training queue (items collected from all data sources) and control training and cleanup.

## What you see

* **Summary counts**: Total items, Pending, Embedding (processing), Completed, Failed, and Tokens used.
* **All Sources**: List or summary of data sources and item counts.
* **Training Queue** table: Items with columns such as **Item**, **Status**, **Tokens**, **Created**, **Actions**.
* **Filters**: By data source, status (All Statuses), or search text.
* **Actions**: Select All, Delete, Re-queue (reset).

Queue item statuses:

* **Pending** – Waiting to be processed.
* **Processing / Embedding** – Currently being sent to the embeddings service.
* **Completed** – Successfully trained.
* **Failed** – Error during training.

## Actions

### Sync

Refreshes content from the data source into the queue (same as in the **Data Source** tab).

### Reset (Re-queue)

Puts a **failed** or **completed** item back to **Pending** so it will be processed again on the next training run.

### Delete

Removes selected queue items.

<Info>
  Deleted items will not be trained again unless they are added again by a new sync.
</Info>

### Run training

Use the link to the **Scheduler** module and run the **T3AC Training** task for this site.

When the task runs, it:

* Processes all **Pending** queue items (generates embeddings).
* Runs cleanup of old completed/failed items according to the retention setting.

## Training behaviour (simple terms)

* Only items in status **Pending** are processed when training runs.
* **Processing** means: the text is sent to the configured embeddings service, and the result is stored for search/chatbot usage.
* After success, the item is marked **Completed**; on error, **Failed**.
* How often training runs depends on the Sync interval of your data sources and on the Scheduler actually being triggered (e.g. via cron).
