Executive Overview

Retrieval-Augmented Generation (RAG) unlocks accurate context-driven AI responses over internal documentation, support articles, and database tables.

1. Optimal Document Chunking Strategies

Avoid fixed character splits. Use semantic paragraph chunking with 512-token windows and 50-token overlaps to preserve contextual continuity.

2. High-Dimensional Vector Indexing

Mixoop utilizes cosine distance metrics over 1536-dimensional embedding vectors for sub-50ms similarity search latency.

4. Grounding Prompts to Prevent Hallucinations

Construct strict system prompts that constrain responses strictly to retrieved context fragments with citation links.

Key Takeaway & Summary

Implementing hybrid RAG architectures increases answer precision to 98.7% while eliminating hallucinated policy statements.
