🔹 Go to the Official Website → Ollama Download
🔹 Choose the right version for your OS (Windows, macOS, or Linux).
🔹 Download the installer and run it.

Once installed, Ollama will handle all the heavy lifting of setting up DeepSeek for you.

Step 2: Download and Install the DeepSeek-R1 AI Model

Now that Ollama is installed, let’s get DeepSeek AI running on your PC.

1️⃣ Open your Command Prompt or Terminal:

  • Windows: Press Win + R, type cmd, and press Enter.
  • Mac/Linux: Open the Terminal app from Applications.

2️⃣ Run the following command to install DeepSeek:

ollama pull deepseek-r1

🔹 This will download and install the default DeepSeek-R1 model on your system.

Step 3: Select the Best Model Parameters for Your PC

AI models come in different sizes—larger models are smarter but require more computer resources.

💡 Tip: If you’re unsure, start with the 7B model for a balance of performance and capability.
If your PC has limited RAM (below 16GB), stick with 1.5B or 7B for best performance.

Step 4: Run DeepSeek AI Locally on Your PC

Now that the model is installed, let’s start using it.

1️⃣ Open Command Prompt/Terminal again.
2️⃣ Run the AI model:

ollama run deepseek-r1:7b

3️⃣ Start chatting with DeepSeek AI!

  • Type any question, and it will respond instantly.
  • No internet is required.

Step 5: Install Chatbox AI for a Better Interface (Optional but Recommended)

Using AI from a command line isn’t always convenient. Let’s install Chatbox AI, a free chat interface for local AI models.

🔹 Go to: ChatBoxAI Download
🔹 Download the app for Windows/Mac/Linux.
🔹 Install and open it on your PC.

Now, let’s link it to Ollama and DeepSeek.

Step 6: Connect DeepSeek AI to Chatbox AI

1️⃣ Open Chatbox AI
2️⃣ Go to Settings
3️⃣ Click on “Chatbox AI”
4️⃣ Select Ollama API as the backend
5️⃣ Choose the DeepSeek-R1 model from the list
6️⃣ Save the settings
