Faiss installation requires conda. - **Adopt for:** FlashRAG caters to Python-based RAG research with streamlined installation options and flexibility in optional dependency choices for improved performance. - **License detail:** FlashRAG is distributed under the MIT License ## Choose when ### Choose rag-web-ui if… - rag-web-ui is primarily TypeScript; FlashRAG is Python. - License: rag-web-ui is Apache-2.0, FlashRAG is MIT. - Tags unique to rag-web-ui: ai, deepseek, langchain, ollama. - Also covers Evaluation & Observability. - rag-web-ui ships Docker support for self-hosted deployment. - For projects needing real-time interactive AI capabilities backed by a strong emphasis on data retrieval accuracy. ### Choose FlashRAG if… - FlashRAG is primarily Python; rag-web-ui is TypeScript. - License: FlashRAG is MIT, rag-web-ui is Apache-2.0. - Requirements: Python version greater than or equal to 3.10; Optional dependencies include vllm, sentence-transformers, pyserini. Faiss installation requires conda.. - Tags unique to FlashRAG: benchmark, datasets, large-language-models, python. - Also covers Model Training. - When you need specialized tools for retrieval-augmented generation (RAG) within large-language-model environments, offering a direct pip install option simplifies quick integration into your projects. ## When NOT to use rag-web-ui - Avoid if your project mandates minimal configuration steps, as it involves setting up environment variables and running Docker services. - Not suitable for teams strictly preferring languages other than TypeScript for their development flow. ## When NOT to use FlashRAG - Avoid using FlashRAG if you do not have Python version 3.10+, as the toolkit requires this minimum Python version. - Do not use FlashRAG when your research or project involves extensive use of faiss, because it needs to be installed via conda due to pip installation incompatibilities. ## Common questions ### What is the difference between rag-web-ui and FlashRAG? rag-web-ui: An intelligent dialogue system based on RAG technology.
