Why Your Enterprise AI Looks Impressive Yet Produces Garbage Results

Even with the world’s best large language models, chaotic internal notes, calls, and processes turn enterprise AI output into junk; a five‑layer architecture—capture, retrieval, source‑truth, permission, and feedback—plus a six‑question test can turn a noisy "company brain" into a useful tool, as shown by Single Grain’s dramatic time‑saving results.

MMR for RAG: Low-Cost Chunk Limits Balance Relevance and Diversity

When a long document is split into many highly similar chunks, vector‑based top‑k retrieval tends to return multiple pieces from the same source, causing document dominance; applying a per‑document chunk limit together with Maximal Marginal Relevance (MMR) re‑ranking introduces diversity while preserving relevance, offering a low‑cost way to improve RAG answer quality.
