## 📰 News
- **[2026.02.02]** Release **RynnBrain family** weights and inference code.
- **[2026.02.02]** Add cookbooks for cognition, localization, reasoning, and planning.
## ✨ Introduction
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.
### Key Highlights
- **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 awareness.
- **Physical-space grounded reasoning (RynnBrain family)**
The broader RynnBrain family includes “Thinking” variants that interleave textual reasoning with spatial grounding to anchor reasoning in reality.
- **Physics-aware precise planning (RynnBrain family)**
Integrates localized affordances/areas/objects into planning outputs to provide downstream VLA models with precise instructions.
