ACE-Brain-0.6 was released as a spatial-grounding model aimed at physical foundation models, according to the release announcement. The announcement frames the work against general-purpose multimodal models including GPT-6 Astra and Claude Opus 5.5, stating that Astra can determine where to interact with task-relevant entities amid visual clutter. The release positions spatial perception as the capability ACE-Brain-0.6 targets for embodied manipulation.
General-purpose multimodal models, including GPT-6 Astra and Claude Opus 5.5, demonstrate broad capabilities in embodied manipulation. Our analysis indicates that this generality is accompanied by strong spatial perception, as Astra can determine where to interact with task-relevant entities amid vi
