Industrial AI Governance & MLOps worked example

Model Retraining Cost at 72% share of full retraining scope included: a worked example

This worked example runs the model retraining cost numbers for a tougher week than the baseline: 72% share of full retraining scope included instead of the typical 100%. Estimate the cost of retraining industrial AI models using retraining runs, cost per run, scope, and fixed validation adders.

The inputs for this scenario

  • Planned model retraining runs: 8 runs (held at the documented default)
  • Compute and labeling cost per retraining run: 3,200 $ / run (held at the documented default)
  • Share of full retraining scope included: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed validation and sign-off cost: 6,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable model retraining cost = planned model retraining runs × cost per retraining run × retraining scope included.
  • Total model retraining cost works out to 24,932 $ at these inputs, and this is the headline figure for the scenario.
  • Retraining cost per planned run works out to 3,117 $ / run at these inputs.
  • Variable model retraining cost works out to 18,432 $ at these inputs.
  • Fixed retraining validation adders works out to 6,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of full retraining scope included sits at 100% and the headline result is 32,100 $, this scenario comes in 22.33% below the baseline at 24,932 $.
  • Use it when setting an annual MLOps budget, comparing retraining cadences, or building the cost side of a business case for keeping a model in production. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total model retraining cost: 24,932 $ (headline result)
  • Retraining cost per planned run: 3,117 $ / run
  • Variable model retraining cost: 18,432 $
  • Fixed retraining validation adders: 6,500 $
