Artificial Analysis's AA-PersonalityBench compares top open-weights and proprietary LLMs across 30 personality traits. Results show open-weights models rank significantly lower than proprietary ones in truthfulness, pragmatism, and structure (with a 32-point gap in truthfulness), while scoring higher on 'slop' and bottom-line summarization. This highlights current gaps in the open-source ecosystem regarding reasoning rigor and content conciseness.

    AA-PersonalityBench: Open Weights Models Lag Proprietary in Truthfulness and Structure

    • Open-weights models rank 32 points lower than proprietary models on average in Truthfulness, the largest gap observed.
    • Proprietary models outperform open-weights in Pragmatism, Natural Sounding, Evidence-Based, and Structured traits.
    • Open-weights models score higher on 'Slop' and 'Bottom-Line Summary', indicating different stylistic tendencies.
