In AA-PersonalityBench, the top open weights models on average rank lower than the top proprietary models on truthfulness, pragmatism and structure, and higher on slop and summarizing the bottom line

We compared the 10 open weights and 10 proprietary models measured with the highest Artificial Analysis Intelligence Index scores. Each model is percentile ranked from 1 to 100 on each of 30 personality traits. On average, the top open weights models rank 32 points lower than the top proprietary models on Truthful, the largest gap of any trait.

Average rank, top proprietary vs. top open weights:

➤ Open weights rank lower: Truthful (79 vs. 47), Pragmatic (79 vs. 49), Natural Sounding (77 vs. 52), Evidence-Based (76 vs. 47), Structured (73 vs. 45) and Literate (70 vs. 47)
