Project Overview

Farfalle is an open-source AI-powered search engine designed to function similarly to Perplexity. It allows users to run local language models (LLMs) such as llama3, gemma, mistral, and phi3 or utilize cloud models like Groq/Llama3 and OpenAI/gpt4-o. The project is managed by Rashad (GitHub handle: rashadphz), and it aims to provide a versatile, self-hosted search solution that can be deployed locally or in the cloud. The repository has seen significant activity since its creation on April 25, 2024, with a total of 173 commits. The project is actively maintained, with recent updates indicating ongoing development and improvements.
