Fixing Critical Custom AI & RAG Engineers Bottlenecks
Root Cause: LLMs generating plausible-sounding but completely fictitious claims when context is missing from naive vector search.
Root Cause: Translating queries through generic models without preserving regional idioms and legal terminology.
Root Cause: Passing unredacted customer names, emails, and sensitive financial records directly to third-party public LLM APIs.
