    微软研究院开源 Orchard 智能体框架,并发布三个领域训练方案

    微软研究院推出开源框架 Orchard,核心是 Orchard Env,一个基于 Kubernetes 的轻量环境,可并行创建、管理和移除数千个隔离组件,用于数据收集、强化学习 rollout 和评估。团队同时发布 Orchard-SWE、Orchard-GUI、Orchard-Claw 三个领域训练方案及训练数据与评估方法。Orchard-SWE 在 SWE-bench Verified 上从 61.4% 基线提升至 69.7%,加入价值模型重排序后达到 73%;Orchard-GUI 训练 4B 参数视觉语言模型,在 WebVoyager、Online-Mind2Web、DeepShop 上平均 68.4%。

    Alongside the models and workflows, the project releases training data and evaluation methods intended to help the broader research community build and study open agentic systems. Artificial intelligence is rapidly moving beyond static question-answering toward autonomous agents that can plan, reason, and act across complex, multistep environments. These systems can fix bugs in complex codebases, navigate the web on a user’s behalf, and manage workflows involving calendars and email. While there

    OpenRouter 发布 Ori Eval,为你的项目自动挑选最合适的模型

    OpenRouter 发布 Ori Eval,一个面向产品内模型的评测工具,可让编码智能体扫描代码库中调用模型的位置,确认成本、性能、延迟、工具调用准确率等偏好后,从最新模型中选出 5 个候选并生成 review.eval.ts 文件,用 bun test 并行跑评测并给出带理由的推荐。评测文件会检查智能体调用了哪些工具、避开了哪些工具以及答案质量,开放式回答由 LLM-as-a-judge 按设定标准打分。单次评测通常花费 10 到 30 美元,可接入 GitHub Actions,评测失败即构建失败,也可定期重跑并在新模型更优时自动开 PR。
