UnverifiedMonolithic VLA models receive visual and language inputs and directly generate raw motion commands or very short action sequences, lacking reusable behavioral abstractions.70% similarUnverifiedStandard world models typically only fit observed trajectories, which is not the quantity needed for planning under intervention.66% similarUnverifiedWorld models emphasize modeling causal relationships, physical laws, and environmental dynamics, rather than simply predicting text sequences.64% similarUnverifiedTransformer models excel at capturing statistical correlations in text, but lack the ability to build world models and cannot internally simulate the causal chains and long-term consequences of physical world operations.64% similarUnverified多模态大模型（VLM）不是OCR，它在视觉向量上进行注意力计算并结合语言先验推断内容，对无规律哈希值会产生幻觉而非报识别失败62% similar
