Interview Prompt
For each model (`mdl_name`), find the framework used across the greatest number of its versions, breaking a tie in that count by the higher average accuracy. Sort the resulting model-framework pairs by average accuracy, highest first, and keep every pair whose accuracy places it among the three highest values, including any that share a position.
Summary
Every framework has a star model.
