The Real Cost of Running AI Features (and How to Cut It by Half)

Caching and prompt compression

Prompt caching for shared context and trimming redundant instructions typically save 30–50% with no quality loss.

Right-size the model per step

Using a frontier model for every step is the most common overspend. Most pipeline steps run fine on small models.

Batch and async where users won't notice

Background enrichment, summarisation, and classification can use batch APIs at a fraction of real-time pricing.

Why this matters in 2026

Boards and founders are asking the same question in 2026: where does AI genuinely move the numbers, and how do we get there without wasted pilots? This article lays out the decision framework we use with clients — from opportunity mapping to vendor selection to budgeting — grounded in what has actually worked.

Step-by-step: how to approach it

1. Map processes by volume and variability. High-volume, judgement-heavy, document-rich processes are the sweet spot.
2. Quantify the outcome before the build. Hours saved, revenue protected, errors avoided — with a number the sponsor would celebrate.
3. Check data readiness. Where does the data live, how clean is it, who owns it, and what can leave your boundary?
4. Pilot with fixed scope. One use case, one eval target, one date. No open-ended research.
5. Plan for operations. Who owns prompts, monitoring, and costs after launch? Budget for AI-ops from day one.

At a glance

Common mistakes to avoid

• Starting with the technology instead of the process and outcome.
• Company-wide model standardisation — model choice should be per task.
• Open-ended "AI exploration" budgets with no eval target or date.
• Underestimating running costs and change management.
• Skipping data foundations and expecting AI to compensate.
