A new research paper explores the effectiveness of "thinking chains" in visual language models (VLMs) for quantifying uncertainty. The study found that while some models like Qwen3-VL-8B-Thinking exhibit a complete collapse in uncertainty signals, others like GLM-4.1V-9B-Thinking show no such degradation. InternVL3-8B demonstrated selective thinking, only generating chains for a portion of queries. The research suggests that signals from these thinking chains are more reliable predictors of uncertainty than answer entropy, especially for complex reasoning tasks. AI
IMPACT This research suggests that the internal reasoning processes of VLMs can provide more reliable uncertainty quantification than their final answers, potentially improving model trustworthiness.
