# Custom Model Create

> Submit training request to create custom model

<Info>
  This is **Step 3** of the Custom Model workflow. You must complete [Step 2: Upload](/api-reference/suno/customModelUpload) (at least 6 files) first. See the [full workflow guide](/api-reference/suno/customModel).
</Info>

<Warning>
  This step costs **100 credits** and training takes approximately **2-3 minutes**. The returned `taskId` is the same as your `sessionId`.
</Warning>

On success, the task result contains the custom model details. The model ID (format: `chirp-custom:<uuid>`) can be used directly in the [Generate](/api-reference/suno/generate) endpoint's `model` field.

<Tip>
  If create fails due to a parameter error, you can retry with the same `sessionId` — the system automatically resets the session state.
</Tip>
