I need to identify the main categorical columns and find their most common values with frequencies. Let me start by examining the dataset structure to understand which columns are categorical. ```json { "action": "tool_call", "reasoning": "The dataset card lists several classifiers (categorical columns) but doesn't show all 61 columns. I need to inspect the raw.all_ai_models table to see all columns and their types to identify the main categorical ones.", "tool": "inspect_columns", "args": { "table": "raw.all_ai_models" } } ```
