Claude 網頁版、桌面版和行動版下週起將預設使用 auto mode

Anthropic 的 Claude 帳號在 X 上宣布，從下週起，Claude 網頁版、桌面版和行動版 app 的 Pro、Max 和 Team 方案工作階段將預設使用 auto mode。系統會透過自動檢查攔截有風險的操作，而非要求使用者逐步核准。使用者隨時可以切回手動核准。Anthropic· 程式開發· 1 則討論

Anthropic 建議將子代理整合進主代理迴圈，並推出遷移工具包

在一篇日期為 2026 年 10 月 22 日的文章中，Anthropic 的 Applied AI 團隊表示，在 Claude Platform 上的數個企業部署案例裡，使用 skills 和工具搜尋的單一代理，在品質上往往勝過單一提示設計和子代理設計，成本與延遲也經常較低。該團隊表示，有位客戶從多代理框架改為單一迴圈後，執行速度約提升 2 倍。這些是 Anthropic 自行觀察的結果，並非已公開的測量數據。Anthropic· 模型· 2 則討論

Anthropic describes Scion, the in-house version control system it moved to from git

In an engineering post dated October 19, 2026, Anthropic says merges to its monorepo grew from about 2,500 to more than 30,000 a day, making source control the biggest development bottleneck. It says its team built Scion, an in-house version control system designed for always-online agents, and migrated off git in five months.Anthropic· 模型

Anthropic says Claude designed quantum circuits better than the best published ones

Anthropic published "Designing more efficient quantum circuits with Claude" on Oct 16, 2026. Per its summary, it gave Claude plain-language specifications for eight quantum circuits, plus an automated evaluator to check and score the designs. Anthropic says Claude, working largely on its own, improved on the best published circuits, in some cases by an order of magnitude or more. The results are Anthropic's own claim and have not been independently checked.Anthropic· 模型

Anthropic: small AI models may be months from self-replicating on IoT devices

Anthropic published "AI models may be capable of self-replicating without access to a datacenter" on Oct 12, 2026. Its summary says its experiments suggest small AI models may be only months away from being capable enough to self-replicate on commercial IoT devices such as Android TVs and smart ovens. The timeline is Anthropic's own projection.Anthropic· 模型

Anthropic says it has cut illicit distillation of Claude by more than 90%

Anthropic published "Strengthening our defenses against distillation attacks" on Oct 12, 2026, on its news and research pages. Anthropic says illicit distillation lets model developers copy frontier capabilities without building proportionally robust safeguards, and that the measures it describes have reduced the rate of distillation by more than 90%. The figure is Anthropic's own claim.Anthropic· 模型
