    NVIDIA 如何用 AI 智能体为仿真准备 3D 场景

    NVIDIA 展示了一套基于 Omniverse Libraries 的智能体工作流,把 Blender 场景处理成可用于机器人仿真的 SimReady OpenUSD 资产:Codex(由 OpenAI GPT-6 Astra 驱动)或 Claude 负责统筹任务,NVIDIA NemoClaw 部署基于 Hermes 的专用子智能体,调用 ovphysx 编写物理属性、ovrtx 渲染预检视图,并执行 SimReady 验证。OpenUSD 作为共享契约层保留层级与元数据,智能体可迭代添加语义标签、碰撞网格、刚体属性和相机与激光雷达传感器定义,最终交付给 Isaac Sim 或 Isaac Lab。

    NVIDIA 用 AI 智能体将 cuTile Python 内核翻译为 cuTile Rust

    NVIDIA 在 TileGym 仓库中推出 AI 智能体技能,将 cuTile Python 和 Triton-TileIR 内核翻译为 cuTile Rust,已移植全部 24 个公开 TileGym 算子,平均达到 cuTile Python 性能的 99.5%。该流程采用有界多智能体工作流,每阶段以机器可校验的判定收尾,并通过与参考 Tile IR 做 diff 验证结构等价。在 NVIDIA DGX B200 上,24 个算子的几何平均加速比均超过 0.95 阈值,整体性能持平于 0.995。

    easy as it is in Python: change the kernel, run the test, and the new binary is already in place. The tilegym-converting-python-to-rust agent skill , shipped in the NVIDIA/TileGym GitHub repo, is built around one design decision: the agent that loads it does no engineering work at all . Reading SKILL.md turns the top-level agent into a pure orchestrator whose only authority is routing; the work happens in specialized subagents it spawns, each loading only the reference documents its stage needs.

    Redwood Research 提出 NLS depth:衡量模型不可言说串行推理的代理指标

    Redwood Research 提出 NLS depth(Natural-Language-rooted node-Separated depth),用于量化模型在不经过自然语言瓶颈的情况下能执行的串行认知量,是对 GDM 论文中“不透明串行深度”概念的具体化。该指标要求瓶颈节点由预训练先验初始化并输出自然语言(含代码、JSON、图像 patch),且不扩展输出空间,可在训练前仅凭架构与训练配方判定。作者认为 NLS depth 可与可监控性、无 CoT 能力追踪互补,但对其对后训练选择不敏感。
