Metric: Mean criterion pass rate (%): share of individual rubric criteria satisfied, over 200 human-screened interrupted conversations in which the user barges in mid-response with new task information (pre-generated cloned-voice audio, fixed barge-in timing), each model response graded blind by human annotators against an instance-specific rubric; higher is better. Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 4 models tracked.
