In the AVO configuration, the LLM operated in a text-only modality: each observation was supplied as an exact 64 x 64 text grid, with no images or image tokens sent to the model.
与 VISTA 对照时的关键混杂项：对方主配置喂 512×512 渲染图，AVO 直接喂 64×64 文本网格。感知通道都换了，动作效率自然不可比。要警惕把“观测表示的胜利”读成“智能体架构的胜利”——真正的运行单元是模型×harness×工具环境×上下文策略。
