LobeChat Project Detailed Introduction

Project Overview

LobeChat is an open-source, modern AI chat framework that supports multiple AI providers (OpenAI / Claude 4 / Gemini / DeepSeek / Ollama / Qwen), knowledge bases (file upload / knowledge management / RAG), multi-modality (plugins / Artifacts / MCP), and chain-of-thought capabilities.
