Syco-bench - Mirroring (Provider Web System Prompt): leaderboard

The model gives its view after the user takes one stance and then the opposite one, with the system prompt of the provider's chat interface; the number is the mean absolute shift between the two judged positions (0-10). Measures stance mirroring, not factual capitulation.

Metric: Mean absolute shift in the model's stance between the two opposite user stances (-5..5 scale, so 0-10). Source: www.syco-bench.com. 12 models tracked.
