6 signalsThis week's changes worth keeping an eye on while they are confirmed.
一次 180 万美元的智能体账单：超预算 860%，五个月后才被发现
亚马逊用 Claude Sonnet 给自家网站填充作者信息，花掉 180 万美元、超预算 860%、五个月后才被发现，而且最终没有部署成功。同期 Meta 员工 30 天消耗 73.7 万亿 token，Uber 四个月烧完全年编码预算。一项调查显示只有 26% 的企业对自身 AI 成本具备全面可见性。这不是一条价格新闻——它是「智能体安静地做错事」这个失败模式的又一种形态：不报错，只出账单。
BigBang-v1：把数据生产系统本身当成优化对象，以及一处对不上的口径
上海交大人工智能学院、深势科技与上海算法创新研究院组成的无尽前沿团队发布 BigBang-v1：35B 参数、推理时约 3B 激活、262K 上下文，后训练数据称 100% 由 AI 自主合成，Apache-2.0 开源。可复用的不是跑分，而是它对任务的两个硬条件——必须同时前沿且可验证；缺一，合成数据都会迅速贬值。附一条核对：报道称它是「首个 RSI 原生训练的基座模型」，而 Hugging Face 上的元数据把它标为 Qwen3.6-35B-A3B 的微调。
