You can ensure factual correctness in AI-generated summaries by integrating retrieval-augmented generation (RAG) with fact-checking mechanisms against authoritative sources.
Here is the code snippet you can refer to:

In the above code, we are using the following key approaches
- 
Retrieval-Augmented Generation (RAG): Uses a vector database (FAISS) to ensure summaries are grounded in source documents.
 
- 
Fact-Checking Mechanism: Cross-validates summaries against stored technical information.
 
- 
Contextual AI Processing: Employs OpenAI's LLM to refine language while maintaining accuracy.
 
- 
Scalability: Adaptable to various technical manuals and document sources.
 
Hence, by combining RAG with fact-checking, AI-generated summaries remain accurate, trustworthy, and accessible to non-experts.
