397B 的开源模型，在四项 GUI 基准上超过了 2.4T 的 Qwen3.8-Max 和 2.8T 的 Kimi-K3。 这是北坡刚开源的 NorthCUA，基于 Qwen3.5，有 Nano、Mini、Pro 三档，加一套 Harness，配 120 多页技术报告。报告副标题写得很实在：Turbocharging Computer-Use Agents through Experience at Scale。 分数先摆出来：ScreenSpot-Pro 93.3、OSWorld-Verified 88.6、WebArena-Verified 73.9、OSWorld-G 91.0，都是开源里最高的一档。 但真正值得看的是经验怎么造出来的。三个组件咬在一起：Harness 负责持续交互，把上下文压成近期视觉窗口加快照历史，旧坐标和失效页面引用会从摘要里清掉，工作区一直保留到验收结束；Experience Flywheel 有三条造任务的路，从功能与文件反推需求、从真实需求倒推环境、从带验证器的种子任务做变体；Staged Learning 走广覆盖 GUI 训练、长程监督微调、桌面与 Web 联合 GRPO 三段。 有个细节很能说明问题：Inkscape 里长得一样的两个「左对齐」图标，一个是移动图形，一个是调文本框段落的对齐。样本构造时必须先用软件文档确认控件语义，否
