Prevent it by design, not after the fact. Segment knowledge sources by locale and region with metadata filters applied at retrieval time. Configure retrieval to prefer canonical language articles with fallback translation disclaimers. Add monitoring and alerts so you catch issues before users do. Multilingual RAG fails silently when retrieval returns wrong-language chunks that look plausible. Optimize for scale and operational observability.
Architect Perspective
Multilingual RAG fails silently when retrieval returns wrong-language chunks that look plausible. Explicit locale filters and citation mandates catch hallucinations early. Regional policy differences should be modeled as data dimensions, not buried in prompt instructions.
