  • Developers or users assessing the project's documented conversation and personality-management features.

Documented uses

  • Resume, rename, add or remove conversations.
  • Export conversation history as text or the database as JSON.
Before you choose

Requirements & limits

  • The README marks the project deprecated and names Lord of Large Language Models as its replacement.
  • Documented backends include llama.cpp and two GPT-J backend options; Hugging Face Transformers is described as under construction.
  • The Windows automatic-install instructions require Python 3.10 and Git.
  • The README specifies AVX2 for the pyllamacpp backend and gives an approximately 4 GB size for the default model.
  • Audio input and output are listed, with Chrome specified for those features.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install the web interface with the documented Windows script

Use the README's Windows automatic-install path to start the chat interface.

Before you start

  • Windows 10 or 11
  • Python 3.10 installed from the official Python distribution, not the Microsoft Store version
  • Git
  • An AVX2-capable CPU when using the pyllamacpp backend

Steps

  1. Download the Windows webui.bat script from the release section and place it in a folder for the application.

  2. Run the script and allow it to download the required files; accept a model download or provide a model appropriate for the backend.

  3. Open http://localhost:9600 in a web browser.

Expected outcome

The README says the script should install the application and start the chatbot, available in a browser at localhost:9600.

Guide limitations

  • The project is deprecated and identifies Lord of Large Language Models as its replacement.
  • The README's default model is roughly 4 GB.
  • AVX2 is specified for the pyllamacpp backend.
