The default model used is `Qwen/Qwen2.5-7B-Instruct`. You can **right-click** the service icon in the top-right corner of the translation window to go to the "Translation - Services" page and switch to other free models.
As shown in the image below, the models marked as **Free** can be used directly.
### 3.3 Using Other Text Generation Models from SiliconFlow
To use models that are not marked as free, you need to obtain a SiliconFlow API Key.
1. Go to the [SiliconFlow official website](https://cloud.siliconflow.cn/) and register an account (or log in if you already have one).
2. After registering, open the [API Keys](https://cloud.siliconflow.cn/account/ak) page and create a new API Key. Click to copy the key for future use.
3. Go to the previously mentioned "Translation - Services" page in Bob, paste the API Key into the **SiliconFlow Translation** service’s API Key setting, then switch to the desired model and click save to start using it.
