How to Install FlowiseAI on Your Synology NAS

FlowiseAI is an Open Source Graphic User Interface to build your customized LLM flow on LangChain. LLM (Large Language Model): A large language model (LLM) is a deep learning algorithm that can perform a variety of natural language processing (NLP) tasks. These models (also referred to as neural networks) are typically built on transformer architectures and are characterized by their extensive training on massive datasets. Large language models (LLMs) like GPT-3 and similar models can be used to develop a variety of applications across different domains e.g. LLM Chains, GenApps, Prompt Chaining etc. In this step by step guide I will show you how to install FlowiseAIĀ on yourĀ Synology NASĀ using Docker & Portainer.

šŸ’”Note: This guide works perfectly with the latest FlowiseAI v.3.0.1Ā release.

Iā€™ve been very honest about this aspect of my work since the beginning: I donā€™t run any ADS, I donā€™t require subscriptions, paid or otherwise, I donā€™t collect IPs, emails, and I donā€™t have any referral links from Amazon or other merchants. I also donā€™t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. Itā€™s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
