A common failure pattern in Saudi enterprise RAG projects is budget flowing toward model access, interface polish, and vendor comparison while retrieval evaluation remains informal. The result is a system that looks modern but cannot answer consistently when documents are long, bilingual, or policy-heavy.
The missing investment is not glamorous. Teams need representative question sets, gold evidence spans, versioned document collections, Arabic-English evaluation cases, and clear thresholds for abstention. Without this foundation, switching models only relocates the uncertainty.
RAG value in the Saudi market depends on local evaluation discipline: Arabic terminology, regulatory phrasing, document hierarchy, and domain-specific failure cases. The model matters. The evidence pipeline matters more.
