    Anthropic 的 Bun 完成 Rust 重写并合并入主仓库

    Anthropic 旗下 JavaScript 运行时 Bun 的 Rust 重写版本已合并入主仓库,新增超过一百万行代码,作者 Jared Sumner 称其在所有平台通过测试套件、修复部分内存泄漏并将二进制体积缩小 3 至 8 MB。Sumner 表示性能持平或更快,架构与数据结构不变,且团队已数月不自己写代码,主要依靠 Claude Code 维护。此前移除约 60 万行 Zig 代码的第二个 PR 被 GitHub 标记为 AI slop 并关闭。

    安大略审计发现医生AI记录工具频繁出错

    加拿大安大略省审计长办公室对20家获批AI Scribe系统进行评估,发现9家系统编造了录音中未讨论的信息并给出治疗建议,12家写入错误药物信息,17家遗漏患者心理健康的关键细节。报告还指出评分权重失衡,是否在安大略本地设有机构占30%评分,而医疗记录准确性仅占4%,偏见控制、威胁与隐私评估各占2%。OntarioMD建议医生手动复核AI记录,但获批系统均无强制确认功能。

    OpenAI 总裁庭审称今年将烧掉 500 亿美元算力

    OpenAI 联合创始人兼总裁 Greg Brockman 在周二庭审证词中表示,公司预计到今年年底将在算力上烧掉 500 亿美元,该数字此前由 Bloomberg 报道。文章指出,亚马逊、Nvidia 和软银 2 月宣布的 1100 亿美元投资中至少 800 亿美元附带条件,例如 OpenAI 需租用 2 吉瓦亚马逊 Trainium 加速器并在 AWS 部署 GPT 模型才能拿到 500 亿美元中的 350 亿美元,Nvidia 的 300 亿美元投资则与 5 吉瓦训练和推理算力部署挂钩。

    Anthropic 调整 Claude Code 缓存默认值,用户反映配额消耗加快

    Anthropic 上月将 Claude Code 提示缓存的 TTL 从一小时缩短到五分钟,称此举不会增加成本,但用户反映配额消耗更快。用户 Sean Swanson 的 bug 报告显示,一小时缓存约在 2 月 1 日引入,3 月 7 日前后改回五分钟。Anthropic 的 Jarred Sumner 称改回五分钟反而更便宜,因为相当一部分请求是一次性调用;Claude Code 创建者 Boris Cherny 表示正在研究默认 40 万 token 上下文窗口,并保留 100 万 token 选项。

    March 7. "The 5m TTL is disproportionately punishing for the long-session, high-context use case that defines Claude Code usage," said Swanson. When using AI coding assistants or agents, the context is additional data sent along with the user's prompts, such as existing code or background instructions. Context improves the accuracy of the AI but also requires more processing. Claude prompt caching avoids re-processing previously used prompts including context and background information. The cac
