Ollama

Ollama is a powerful tool for running large language models locally on your machine. It provides a simple way to download, run, and manage open-source models like Llama, Mistral, and many others directly on your local hardware.

Get Started

Step 1: Install Ollama

1. Download and install Ollama (opens in a new tab) for your operating system
2. Follow the installation instructions for your platform (macOS, Linux, or Windows) from Ollama Docs (opens in a new tab)

Step 2: Pull a Model

1. Open your terminal or command prompt
2. Pull a model using the Ollama CLI:

ollama pull <model-name>

You can also pull other models like:

• ollama pull mistral
• ollama pull codellama
• ollama pull llama2:7b

Step 3: Start Ollama Service

1. Start the Ollama service (it runs on port 11434 by default):

ollama serve

Step 4: Expose Ollama API

If you're not self-hosting the Lamatic Gateway, you'll need to expose your local Ollama API:

1. Install a tunneling service like ngrok (opens in a new tab)
2. Expose your Ollama API:

ngrok http 11434 --host-header="localhost:11434"

For using Ollama with ngrok, here’s a useful guide (opens in a new tab)

3. Copy the generated ngrok URL (e.g., https://abc123.ngrok.io)

Setup Instructions

Configure in Lamatic

1. Open your Lamatic.ai Studio (opens in a new tab)
2. Navigate to Models section
3. Select Ollama from the provider list
4. Enter your Ollama API URL (Need HTTPS):
   • If self-hosting: http://localhost:11434
   • If using ngrok: Use the ngrok URL from Step 4 above
5. Save your changes

Key Features

• Local Model Execution: Run models directly on your hardware without cloud dependencies
• Wide Model Support: Access hundreds of open-source models from Hugging Face
• Easy Model Management: Simple CLI commands to pull, run, and manage models
• Cost Effective: No API costs - only your local computing resources
• Privacy Focused: All processing happens locally on your machine

Available Models

Ollama supports a wide variety of models including check out the Ollama Library (opens in a new tab)

Configuration Options

• API URL: The endpoint where Ollama is running (default: http://localhost:11434)
• Model Selection: Choose from your locally installed models
• Custom Parameters: Configure temperature, top_p, and other generation parameters

Best Practices

• Ensure you have sufficient RAM and storage for your chosen models
• Use GPU acceleration when available for better performance
• Keep your Ollama installation updated
• Monitor system resources when running large models
• Consider using smaller models for faster inference if speed is critical

Troubleshooting

Ollama service not starting:

• Check if port 11434 is available
• Ensure you have sufficient system resources
• Verify installation was successful

Model not found:

• Pull the model first using ollama pull <model-name>
• Check available models with ollama list

Connection issues:

• Verify Ollama is running with ollama serve
• Check firewall settings if using ngrok
• Ensure the API URL is correct in Lamatic
