The verdict in three sentences
A RAG AI chatbot wired to your knowledge base costs 10,000 to 35,000 EUR in 2026, excluding monthly API cost. It deflects 30 to 50 % of level-1 tickets, dropping the cost per ticket. Success comes from guardrails, helpdesk integration and knowledge freshness, not the model alone.
