Explore alternative smaller models that may aid the java migration use case

We are looking for help to explore smaller models that can either be deployed on-prem or locally and facilitate java migrations.

The issue names no files, tests, or entry points. Start by clarifying which migration tasks and deployment constraints the smaller models must support, then compare suitable local or on-prem options against those requirements. Done should be a documented evaluation with a clear recommendation or next step.
