CTO AI Corner: How to manage rising AI service costs?

While many companies are still trying to get employees to use more AI, some are already starting to see surprisingly large monthly AI bills. Funny how quickly “innovation” becomes “please explain this invoice.” The biggest problem is that most companies still do not actually know what kind of value they are getting from AI. They track utilization percentages and know how people use the tools, but rarely calculate how much business value they get for every dollar spent. That is where the discussion often goes off track.

It does not really matter if license costs increase if the cost per completed unit of work stays the same or becomes lower than before. But if AI only adds new costs on top of existing processes without improving anything else, then there is a real problem.

Measure value, not just usage

AI tools should not be adopted just to improve AI adoption metrics or to tick the “We use AI” box in a board presentation. They should have measurable business impact. That could mean advancing product development faster, gaining an advantage over competitors, or producing the same results with a smaller team. Without measurable impact, it is not an investment. It is just an additional expense.

A good starting point is measuring the thing you actually want to improve with AI. Without a baseline, you will never know what was gained or whether the price was worth it.

During adoption, companies also should not panic too early. Some metrics may even temporarily drop while people are learning new tools and workflows. But if the numbers do not improve enough to justify the cost, then something needs to change.

Maybe people need more guidance and support.

Maybe the selected tool was the wrong one.

Or maybe the AI simply is not capable enough for that task yet.

Not every AI use case is worth keeping

The important thing is that with measured data, companies can make informed decisions. Including the decision to stop using a tool and focus AI efforts somewhere else where the gains are more obvious.

The potential benefits are usually large enough that companies do not need to optimize every billing model, certificate level, or pricing detail in the beginning. First prove that the gains are real. Once the value is clear and the tool is there to stay, then it makes sense to optimize license tiers, billing cycles, and access models.

And of course, monitor who is actually using the service.

Before renewing or expanding AI licenses, companies should ask:

  • Which workflows improved?
  • What baseline are we comparing against?
  • Who actively uses the tool?
  • Which teams generate measurable value?
  • Which licenses are unused or underused?
  • Could some users move to usage-based access?

Buying licenses for everyone when not everyone needs them is not particularly efficient. If leadership wants to say that “everyone has access to AI,” then maybe some roles could use tools without monthly base fees and instead pay only based on actual usage.

Depending on the scale, there may even be a cost advantage in building an internal UI on top of AI APIs instead of paying fixed per-user platform fees.

At some point, companies should probably measure AI ROI with the same seriousness as cloud costs, consulting spend, or headcount planning.
