## Choose when

### Choose all-in-rag if…

- Tags unique to all-in-rag: ai, embedding, langchain, llm.
- Also covers LLM Frameworks.
- - When you want a comprehensive resource that covers both the theoretical foundations and practical application of RAG.

### Choose FlashRAG if…

- 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, retrieval-augmented-generation.
- 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 all-in-rag

- - Avoid if you are looking for a solution that only focuses on theoretical aspects without practical implementation guidance.
- - If your project does not require multi-modal support or is solely focused on text-based applications, more specialized tools might provide better optimization.
- - Not suitable if you're seeking quick prototyping or a light-weight framework; all-in-rag emphasizes comprehensive learning and production-ready practices.

## 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.
