    DeepSeek 计划领投机器人 AI 公司 Winverse AI,估值约 4 亿美元

    DeepSeek 计划领投机器人 AI 公司 Winverse AI,融资规模达数千万美元,美团旗下龙珠资本等投资方已承诺参与,融资完成后 Winverse AI 估值约 4 亿美元(约合人民币 27 亿元)。Winverse AI 创立于 2026 年,专注机器人 AI 模型研发,创始人胡瀚曾任腾讯杰出科学家,负责混元视觉语言模型和具身基础模型团队。若交易达成,这将是 DeepSeek 自 2023 年创立以来规模最大的初创企业投资之一。

    达成,这将成为DeepSeek于2023 年创立以来,规模最大的初创企业投资之一。企查查信息显示,在投资Winverse之前,DeepSeek已投资宇树科技,其持股比例为0.2308%,持股数为933,399股,以合作开发具身智能模型。 据悉,Winverse AI创立于2026年,专注于机器人AI模型研发,目前尚未对外披露太多信息。 根据该公司创始人胡瀚的GitHub个人主页显示,他于2008年获得清华大学学士学位,并于2014年获得清华大学博士学位,师从周杰教授。 胡瀚在创立Winverse AI前是腾讯杰出科学家,负责混元视觉语言模型(VLM)和具身基础模型团队,曾担任混元语言模型技术负责人,并创立了混元语音团队。 在加入腾讯混元之前,胡瀚还曾任职于微软亚洲研究院和百度,在微软亚洲研究院(MSRA)任职期间担任首席研究员和研究经理。 ▲胡瀚的GitHub个人主页 此外,胡瀚参与的论文《Swin Transformer: Hierarchical Vision Transformer Using Shifted Windows》获得了 ICCV 2021 最佳论文奖(Marr Pr

    Google XR Blocks 0.22.0发布:初步支持WebGPU,新增Gemma 4端侧AI及空间交互功能

    Google旗下开源XR开发工具库XR Blocks发布0.22.0版本,首次在桌面模拟器中支持three.js的WebGPURenderer,但空间UI组件尚未支持,仍属模拟器层面的初步适配。新版本新增Gemma 4助手、端侧图像超分辨率、基于EfficientSAM的圈选搜索等端侧AI示例,并将Gemini默认Flash模型更新为Gemini 3.8 Flash、three.js升级至r186。相关端侧AI功能目前主要面向开发者测试与原型验证。

    tSAM-Ti,并新增照片转3D、单目照片生成世界坐标对齐深度信息等演示。 在空间交互方面,此次更新新增可滚动视图、可编辑文本框及支持调整尺寸的卡片组件,同时优化图标渲染方式,以减少绘制调用次数。开发者还可以通过新增的生成式AI示例,将AI生成的虚拟物体放置在真实环境表面,并利用ArUco标记追踪功能实现虚实物体定位。 此外,桌面模拟器新增昼夜光照模式及独立性能分析工具,Roomcraft示例加入跨设备协作功能。底层工具方面,XR Blocks将Gemini模型调用迁移至Interactions API,默认Flash模型更新为Gemini 3.8 Flash,并将three.js升级至r186版本。 不过,Google尚未公布上述端侧AI功能在具体XR设备上的运行性能、延迟或兼容性数据,相关功能目前主要面向开发者测试与原型验证。 来源:Github 投稿/爆料:tougao@youxituoluo.com 稿件/商务合作: 林南(微信 19250561593) 加入行业交流群:林南(微信 19250561593) 元宇宙数字产业服务平台 下载「陀螺科技」APP,获取前沿深度元宇宙讯息
