Practical math for AI builders

ModelMetric Lab is a small technical publishing project focused on calculators that show their assumptions instead of hiding them.

What makes a tool worth publishing?

The output should be reproducible, the formula should be understandable, and the limits should be visible. Where an input changes over time—such as a provider’s pricing—the value belongs in the input rather than hard-coded as an eternal fact.

Editorial standard

Guides are written to explain concepts and workflows, with links to the relevant calculator. We avoid publishing automatically generated pages whose only purpose is to capture a keyword.
