Demo App for llama.cpp Model

A mobile Implementation of llama.cpp

This app is a demo of the llama.cpp model that tries to recreate an offline chatbot, working similar to OpenAI’s ChatGPT. The source code for this app is available on GitHub.

The app was developed using Flutter and implements ggerganov/llama.cpp, recompiled to work on mobiles. Please note that Meta officially distributes the LLaMA models, and they will not be provided by the app developers.

To run this app, you need to download the 7B llama model from Meta for research purposes. You should rename it to ggml-model.bin and place it in your device’s download folder.

Additionally, you can fine-tune the ouput with preprompts to improve its performance.
