The Cost Conversation Nobody Wants to Have

Summary

Many AI projects fail to reach production, not due to technical issues, but because of unaddressed cost conversations. Industry statistics show low conversion rates, with IDC/Lenovo reporting 12% PoC-to-production success and MIT's NANDA report indicating 95% of generative AI projects fail to deliver results. Pilot costs, often as low as a \$5k API bill, dramatically underestimate actual production expenses, which can be 3x to 8x higher. A healthcare case study illustrates this, where a prior-authorization tool's cost escalated from \$200/month in demo to \$22,000/month in actual production, driven by factors like user retries, expanding RAG context, accumulating features, and increased adoption. This discrepancy arises because both vendors and customers avoid detailed cost modeling early, leading to significant budget overruns. The article suggests proactive strategies for transparent cost discussions and outlines technical mitigation levers.

Key takeaway

For AI Product Managers or Directors of AI/ML evaluating new projects, you must proactively address production costs early. Refuse projections without a 10x column, an overage clause, and a fallback plan, as actual costs often exceed pilots by 3x-8x. Insist on per-interaction cost numbers and right-sizing models for specific workloads. This upfront honesty, though politically challenging, prevents commercial failures and ensures long-term project viability, protecting your budget from unexpected overruns.

Key insights

AI project production failures stem from unaddressed cost conversations, not technical feasibility, due to underestimation of scale factors.

Principles

• Production costs are 3x-8x pilot projections.
• Model top-decile users, not average users.
• Assume today's pricing won't last a year.

Method

Conduct cost conversations as a design exercise by modeling top-decile users, putting per-interaction costs on the design table, showing 10x projected production, naming overage responsibility, and accounting for pricing shifts.

In practice

• Implement model routing/cascading for cost reduction.
• Use aggressive caching for RAG workloads.
• Right-size models per workload to avoid frontier model overuse.
