    Trellis.2 与 Pixal3D 原生集成进 ComfyUI

    ComfyUI 将 Trellis.2 和 Pixal3D 两款开源 3D 生成模型原生集成进核心节点,无需自定义节点、编译 CUDA 扩展或降级 PyTorch,并移除了限制商用的 nvdiffrast 与 nvdiffrec 依赖。此次更新还重建了 Load/Preview/Save 3D 节点,新增 Remesh、Decimate、Smooth Mesh Normals、Fill Holes 等网格后处理节点,以及 UV 展开和法线、环境光遮蔽贴图烘焙,形成完整 PBR 材质集。官方说明这两款模型在质量上仍不及 Hunyuan 3D、Tripo、Rodin 等闭源方案,但可在消费级硬件本地运行、按资产零成本且无商用许可限制,需将 ComfyUI 升级至 0.34.0 或使用 Comfy Cloud。

    SGLang 推出 Weight Cache Daemon,引擎重启权重加载从 495 秒降至 0.63 秒

    SGLang 发布 Weight Cache Daemon,这是一个常驻 GPU 进程,把量化后的模型权重留在显存中,通过 CUDA IPC 零拷贝映射给新的引擎实例。基于 Ling-2.6-1T FP8 模型,权重加载从约 495 秒降到约 0.63 秒,端到端启动时间从 8.8 分钟降到 0.528 分钟,减少 93.9%。该组件是 Fast Engine Recovery Framework 的第一阶段,目标是把冷重启压到 10 秒以内、热备切换压到 1 秒以内,目前支持 TP+PP、单机与多机启动,以及未量化和 block-wise FP8。

    ond loading is zero-copy: the engine's param.data pointer is set directly to the IPC-mapped GPU tensor. No data is copied. To achieve this, the engine initializes the model on the meta device (no GPU/CPU memory allocation), then replaces each parameter's data pointer with the IPC-mapped tensor. Post-quantization parameters (e.g., weight scale from FP8 quantization) that were created by process weights after loading() are also cached by the daemon and mapped directly — no re-quantization needed.
