    "content": "**No duplicate rows found in this dataset.**\n\nI checked for exact duplicates by grouping all columns together and looking for rows that appear more than once. The query returned zero results, meaning every row in the 1,311-row dataset is unique.\n\n**What this means:**\n- No two rows share identical values across all 69 columns\n- Each benchmark result entry is distinct\n- No data quality issues from accidental duplication\n\n**Note on near-duplicates:** This analysis checked for *exact* duplicates only. Near-duplicates (rows that differ in just one or two fields, like slightly different scores for the same model on the same task) would require defining which columns constitute a \"duplicate\" and which are allowed to vary. If you're concerned about a specific type of near-duplicate (e.g., same model + task + date but different scores), I can check for that pattern specifically."
