NativeMind Team6 min read
🤔 What is Ollama?
Ollama is a tool that lets you run AI models on your own computer, as simple as installing any desktop app like Chrome. Once installed, you can:
- Use AI completely offline - chat without needing an internet connection
- Protect your privacy - all data stays on your computer and never gets uploaded to the cloud
- Use it for free - no paid subscriptions needed, install once and use forever
- Access multiple AI models - supports various AI models on par with ChatGPT
📋 Pre-Installation Requirements
System Requirements (macOS Example)
- macOS 11 Big Sur or later
- At least 16GB RAM (24GB+ recommended)
- Apple Silicon chips recommended (M1, M2, M3, etc. for better performance)
- At least 10GB available disk space
- Stable internet connection (only needed for downloading)
💡 Pro Tip
Just like running demanding games, AI models require substantial hardware resources. Macs with Apple Silicon chips run AI models most efficiently, while Intel-based Macs can still run them but with relatively slower performance.
