- Download and Install Jan

Download the Installation File

Before you can start using Jan, you need to download the installation package suited for your operating system. This ensures compatibility and provides all necessary dependencies in one setup file.

• Where to find it? 

Visit the official Jan website and go to the download section.

• What version should you choose?

Windows, macOS or Linux.

Installing Jan on your system, the installation process ensures that Jan is properly configured to run on your system without manual setup. This step also installs necessary libraries and dependencies.

- Launching Jan

Once installed, open the application. If prompted, allow necessary permissions to ensure smooth functioning.

- Setting Up and Downloading a Model

Understanding the Need for AI Models, Jan itself is just an interface, it requires AI models to process requests and generate responses.

Navigate to the "Model Hub" within the Jan interface. Here, you can explore various models with different capabilities and requirements.

- Choosing the Right Model

What should you consider?

• Performance Needs: Larger models (e.g., 13B or 30B parameters) generate more accurate responses but require more RAM and computing power

• Hardware Compatibility: Ensure your system meets the model’s minimum requirements (GPU acceleration is recommended for larger models).

• Use Case: Smaller models work well for quick tasks, while larger models are better for in-depth conversations and creative writing.

- Downloading and Activating a Model

Once you've selected a model, click the download button and wait for it to install. After downloading, activate it within the interface.

- Optimizing Jan for Performance

Enabling GPU Acceleration (Optional but Recommended), AI models are resource-intensive, and running them on a CPU alone can slow down response times. If your system has a compatible GPU, enabling GPU acceleration can significantly improve performance.

How to Enable GPU Acceleration

• Go to Settings > Advanced Settings.

• Find the GPU Acceleration option and enable it.

• Ensure your GPU drivers are up to date to avoid compatibility issues.

- Adjusting Model Parameters

Customizing model settings can fine-tune response behavior for better interaction. Some key parameters include:

• Temperature: Controls randomness in responses (higher values = more creative, lower values = more deterministic).

• Context Length: Determines how much previous conversation history is remembered.

• Response Length: Limits the number of tokens generated in a single response.

These settings allow you to balance creativity, accuracy, and efficiency based on your needs.

- Customizing Model Behavior

Setting Up Assistant Instructions, by defining clear instructions, you can shape how Jan interacts with you, improving coherence and alignment with your preferences.

Steps to Customize Instructions:

• Open a new or existing conversation thread.

• Go to the Assistant tab in the right sidebar.

• Enter custom instructions that define behavior, tone, and response style (e.g., “Be concise and professional” or “Use a casual and friendly tone”).

- Experimenting with Different Styles

Try adjusting the instructions and see how they impact Jan’s responses. This is useful for:

• Creating different types of behavior for your assistant: For specific tasks (e.g., a technical assistant vs. a creative writer).

Try different conversation dynamics to find the one that suits you best. With a well-crafted prompt and three or four rounds of questions and answers, you’ll be able to see how the model responds.

- Exploring Additional Features

Switching Between Local and Cloud Models, depending on the task, you might want to switch between local models (for privacy and offline access) and cloud models (for higher accuracy and power).

- How to Connect to a Cloud Model.

• Go to the Model Selector inside an active conversation.

• Select the Cloud tab.

• Choose a provider (e.g., OpenAI, Anthropic) and enter your API key.

• Confirm the connection and start using the cloud model.

Managing Conversations Efficiently, Jan allows you to organize different discussions by using threads. This helps in:

• Separating different projects or topics.

• Keeping track of past interactions.

• Maintaining context for long-term conversations.

- You're now ready to run your AI model locally and offline.

Now that you have Jan installed and configured on your computer, you can start experimenting with different AI models, customizing the assistant’s behavior, and optimizing performance settings.

• Try different AI models to find the one that best suits your needs.

• Refine the assistant’s instructions to align with your preferred interaction style.

• Explore cloud integrations "only when necessary" to access more powerful processing options.

• With this setup, you have a powerful AI interface at your fingertips, fully adaptable to your needs.
