Muse Glimmer 开源：30B 压进消费级显卡，报错不停下
Meta 发布 Muse Glimmer：300 亿参数、Apache 2.0 开放权重，专为常驻本地的智能体工作流设计。4 位动态量化把 55GB 以上的显存需求压到 17 至 20GB，配合 DFlash 推测解码在 M5 Max 与 RTX 5090 上把吞吐提到最多 3.1 倍。真正值得注意的不是尺寸，而是它把「工具调用失败之后怎么办」写进了训练目标：API 或终端命令报错时，模型诊断故障并另找路径，而不是终止执行。
Conceptual integrity and counting lines of code
Simon Willison argues that lines of code can be a meaningful productivity indicator, that the new limiting factor is cognitive capacity, and that conceptual integrity is what coding agents make hardest to keep.
How Much Memory Does Your Agent Actually Need?
Agentic memory is not a feature you switch on; it is a dose you calibrate to the model.
菲尔兹奖得主：模型强在找到那个对象，弱在知道何时放弃
1998 年菲尔兹奖得主 Timothy Gowers 把近期最轰动的几项模型数学成果摊在一起看，发现它们几乎全是「构造出一个对象」而不是「证明一条定理」。他随后否掉了最顺口的解释，给出的替代解释适用范围远超数学：模型的两项确定优势是知道得多、失败得起，于是它在「大量试、试错便宜」的路线上占优；而人类暂时保住的那一项，是走到半路能闻出这条路没戏，从而砍掉搜索树的绝大部分。
Same Cluster, 33 Points More Utilization: What Changed Was the Order
A constraint-aware GPU allocator benchmarked against FIFO across seven scenarios: utilization up to 33 percentage points higher, priority-weighted output up in every one.
Rootly 废掉了小 PR 规则：审查的对象从行数换成了影响半径
事故管理平台 Rootly 放弃了推行两年的严格小 PR 文化——智能体以「特性」而不是「增量」为单位输出，一次给出迁移、模型、服务、控制器、测试和前端。他们试过让智能体产出堆叠 PR，结果技术上没错、业务上更糟。最终的替换不是换工具而是换判据：衡量代码行数改成衡量爆炸半径，安全边界从合并挪到渐进发布，内部审查器对每个 PR 只回答一个问题——如果这个变更有缺陷，会坏掉哪些面向用户的功能。
