The Hallucination Trap
Nothing destroys client trust faster than an AI chatbot inventing a non-existent 70% discount code or promising features your software doesn't support.
To achieve 100% factual accuracy in production, we implement a multi-layered guardrail pipeline.
The 3-Step Verification Engine
- HyDE (Hypothetical Document Embeddings): We re-formulate the customer's query into an ideal document excerpt before performing vector cosine similarity.
- Hybrid Search (Dense + BM25 Sparse): Combining dense neural embeddings with exact keyword matching to handle SKU numbers, dimensions, and exact contract clauses without error.
- Self-Consistency & Citation Verification: The LLM must output direct bracketed citations pointing to real indexed knowledge chunks. If confidence drops below 92%, the agent gracefully routes to human WhatsApp support.
