[2026.02.02] Release RynnBrain family weights and inference code. - [2026.02.02] Add cookbooks for cognition, localization, reasoning, and planning. RynnBrain aims to serve as a physics-aware embodied brain: it observes egocentric scenes, grounds language to physical space and time, and supports downstream robotic systems with reliable localization and planning outputs. - Comprehensive egocentric understanding Strong spatial comprehension and egocentric cognition across embodied QA, counting, OCR, and fine-grained video understanding. - Diverse spatiotemporal localization Locates objects, target areas, and predicts trajectories across long episodic context, enabling global spatial…
