+Wall-OSS-0.5 is an open-source 4B Vision-Language-Action (VLA) model built upon a 3B VLM backbone augmented with action-generation components. It is designed to provide executable robot behavior directly from pretraining. The model was introduced in the [Wall-OSS-0.5 Technical Report](https://huggingface.co/papers/2605.30877).
 
-We introduce **WALL-OSS**, an end-to-end embodied foundation model that leverages large-scale multimodal pretraining to achieve (1) embodiment-aware vision--language understanding, (2) strong language--action association, and (3) robust manipulation capability.
-Our approach employs a tightly coupled architecture and multi-strategies training curriculum that enables Unified Cross-Level CoT—seamlessly unifying instruction reasoning, subgoal decomposition, and fine-grained action synthesis within a single differentiable framework.
-Our results show that WALL-OSS attains high success on complex long-horizon manipulations, demonstrates strong instruction-following capabilities, complex   understanding and reasoning, and outperforms strong baselines, thereby providing a reliable and scalable path from VLMs to embodied foundation models.
+Before task-specific fine-tuning, Wall-OSS-0.5 achieves non-trivial zero-shot real-robot behavior. After fine-tuning, it serves as a strong adaptation prior, significantly outperforming previous baselines in manipulation tasks.
