Privacy Protection: All data is processed locally and never uploaded to the cloud, guaranteeing your privacy and security.

Fast Response: Efficient model design delivers precise content instantly, enhancing the user experience.

Temperature Adjustment: Customize the temperature coefficient to control the creativity and diversity of generated content.

Prebuilt Prompts: Built-in prebuilt prompts help users quickly start tasks and improve efficiency.

Network Environment: A stable internet connection is required to load the model (access to Hugging Face is necessary). For user convenience, the app provides mirror site 
addresses, but loading speeds may vary.
