## Post

We started by giving engineers access to the most expensive AI coding models and as many tokens as they wanted. Adoption took off. So did costs.

At Databricks, we've since reduced AI coding unit costs by up to 90% in some cases through more efficient models, better routing, spend visibility and less token overhead.
