Local models promise to cut API costs and guarantee total source code privacy, but are they really ready to be used every day during our job? To find out, I spent hours testing, configuring, and putting Gemma 4 to work so you don't have to.


During this talk, we will walk through the practical setup to run Gemma 4 both integrated into Android Studio and as an autonomous CLI agent. We will analyze its performance on daily Android developer tasks, comparing it with paid cloud models.


Together, we'll evaluate whether it's truly possible to cut our AI bill while keeping productivity high, taking full advantage of 100% offline inference.
