## Choose when

### Choose FlagEmbedding if…

- License: FlagEmbedding is MIT, rag-demystified is Apache-2.0.
- Tags unique to FlagEmbedding: embeddings, information-retrieval, sentence-embeddings, text-semantic-similarity.
- If you need to integrate semantic search capabilities within your application, particularly where sentence-level embeddings are critical for finding semantically similar text.

### Choose rag-demystified if…

- License: rag-demystified is Apache-2.0, FlagEmbedding is MIT.
- Tags unique to rag-demystified: ai, chatgpt, gpt, question-answering.
- Use when you want an in-depth understanding and customization of the RAG pipeline as it is built from scratch, enabling a deep dive into implementation details.

## 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

## When NOT to use rag-demystified

- Not suitable for those needing out-of-the-box solutions or users who prefer using pre-configured RAG tools as it requires detailed coding knowledge.
- Avoid if the project timeline is tight since building and customizing from scratch can be time-consuming compared to other available pre-built options.
