AA-PersonalityBench: Significant Slop Differences Among Frontier Models
Artificial Analysis's AA-PersonalityBench shows that models with lower intelligence levels generally produce more Slop, but the Slop differences among frontier models remain large. GPT-6 Sol and Muse Spark 1.3 share the same Intelligence Index of 48, yet their Slop rankings are 1st and 80th respectively; Muse Spark 1.3 (Slop 80), Qwen3.8 Max (75) and Gemini 4 Argon (70) belong to the category of high intelligence but also high Slop, while GPT-6 Luna (4) and Claude Haiku 5.5 (9) have relatively low Slop for their intelligence levels.

In AA-PersonalityBench, less intelligent models generally produce more Slop, but Slop still varies widely among frontier models
➤ Same intelligence level but opposing Slop rankings: GPT-6 Sol and Muse Spark 1.3 both score 48 on the Intelligence Index, yet rank 1 and 80 on Slop respectively
➤ High intelligence but also high on slop: Muse Spark 1.3 (Slop 80), Qwen3.8 Max (75) and Gemini 4 Argon (70)
➤ Low slop for their intelligence level: GPT-6 Luna (4) and Claude Haiku 5.5 (9)
