Evaluated <strong>π₀, π₀-FAST, and OpenVLA</strong> under visual, language, and initial-state distribution shifts across simulation and real-world manipulation.</p>SAFECAST: Robust Failure Detection for VLA Policies with Contrast-Set Training and Calibrationhttps://harshithabr.github.io/publication/safecast/Thu, 01 Jan 2026 00:00:00 +0000https://harshithabr.github.io/publication/safecast/
