- If you need to integrate semantic search capabilities within your application, particularly where sentence-level embeddings are critical for finding semantically similar text.
When NOT to use FlagEmbedding
- Avoid using FlagEmbedding if you require real-time or extremely low-latency text matching, as the process may involve significant computational overhead and latency.
- Do not adopt this tool if your application is already heavily invested in a different ecosystem where integration costs would outweigh benefits, unless specific retrieval-augmented capabilities are a

- 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 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.
