Llama v2 7B with 4bit quantization technically needs ~3.5Gb RAM (7B * 0.5byte), practically a system with 6Gb of RAM should suffice

Khoj Chat

Overview

  • Creates a personal assistant for you to inquire and engage with your notes
  • You can choose to use Online or Offline Chat depending on your requirements
  • Supports multi-turn conversations with the relevant notes for context
  • Shows reference notes used to generate a response

Setup

Offline Chat

Offline chat stays completely private and works without internet. But it is slower, lower quality and more compute intensive.

System Requirements:

  • Open your Khoj settings and click Enable on the Offline Chat card

Configure offline chat

Online Chat

Online chat requires internet to use ChatGPT but is faster, higher quality and less compute intensive.

  1. Get your OpenAI API Key
  2. Open your Khoj Online Chat settings, add your OpenAI API key, and click Save. Then go to your Khoj settings and click Configure. This will refresh Khoj with your OpenAI API key.
