academy/RynnBrain: RynnBrain: Open Embodied Foundation Models

Summary

RynnBrain, an embodied foundation model by Alibaba DAMO Academy, excels in video understanding, localization, and physical-space reasoning. It integrates with VLA models for intricate tasks and offers diverse applications like robot task planning and vision-language navigation. The model is available in dense and MoE variants.

Key Takeaways

1. RynnBrain is an embodied foundation model grounded in physical reality, available in two dense variants (2B and 8B) and one mixture-of-experts (MoE) model (30B-A3B).
2. RynnBrain employs a unified encoder-decoder architecture (supporting both Dense and MoE variants) to transform omni-vision inputs and textual instructions into multi-modal outputs, including spatial trajectories, physical pointing, and action planning.
3. RynnBrain integrates the location information of affordance, areas, and objects directly into its planning outputs.
