Gartner: 70% of enterprises will drop vendor-built agentic AI by 2028

Gartner predicts that by 2028, 70 percent of enterprises will abandon agentic AI systems built with vendor assistance as costs rise and customers struggle to modify the technology without outside help. The forward-deployed engineering model can deliver quick early wins but leaves clients dependent on expensive external expertise.

• By 2028, 70% of enterprises will abandon vendor-built agentic AI
• Fewer than 20% of FDE engagements will turn recurring customer needs into core product features
• Gartner warns of 'FDE washing' — ordinary consulting marketed as specialized services
• Gartner previously forecast half of generative AI projects would exceed budgets
