📱 What is a Local LLM on Mobile?

A Local LLM is an AI model that runs directly on your device — not on a server. This means:

  • 🚫 No internet required
  • 🔒 100% private
  • ⚡ Faster response time
  • 🆓 No API key or cost per request

Mobile hardware is now powerful enough to run small-to-medium LLMs using on-device inference.


🎯 Why Use Offline Mobile AI?

  • Privacy: Your chats never leave your device.
  • No API Limits: Use the model as much as you want.
  • Speed: Local inference avoids network delays.
  • Portability: Use AI anywhere — even without network.
