Reasoning Models Stay Miscalibrated: EMNLP Studies on AI Confidence

zhaoran_wang · x · 2026-09-29

Sharing work sparked by Jev/RLCD putting calibration in the spotlight, the authors report: two EMNLP 2025 papers evaluating calibration in reasoning models and VLMs found stronger capability doesn't automatically mean more reliable confidence — task and modality matter. Their ACL 2026 work extends this to agentic RL, explicitly optimizing calibration alongside task performance in tool-using agents ("The Confidence Dichotomy"), arguing calibration becomes a core capability as confidence starts driving real actions.
