Anthropic 推出了新一代車型 Opus 5。這是 Opus 系列的最新版本,距離 Opus 4.8 上線僅約兩個月。公司稱,Opus 5 的價格低於 Fable 5,限制也更少,在多數使用情境下更具實用性。

多項測試超過Fable 5

公告顯示,Opus 5 在此次發布附帶的多項基準測試中超過了 Fable 5。 Anthropic 也強調,這個模型在驗證自身輸出、重複迭代直到完成任務方面表現更強。

公司舉例稱,在一項測試中,Opus 5 能根據不完整提示,自行寫出一套電腦視覺流程。這也是其此次重點強調的能力之一。

不受30天資料保留約束

與 Fable 和 Mythos 不同,Opus 5 不受 30 天資料保留政策約束。 Anthropic 表示,這一點與上一代 Opus 保持一致。先前,這項安排曾引發部分重視隱私權用戶的擔憂。

不過,Opus 5 並非完全放開。 Anthropic 仍對網路安全相關任務保留較強防護,尤其是漏洞利用產生和滲透測試等場景。例如,模型不能被用於掃描軟體二進位檔案中的漏洞,但可以用來尋找原始程式碼中的漏洞。

新增自動回退功能

Anthropic 同時推出一項名為 Automatic Fallbacks 的測試功能,供用戶選擇開啟。若要求觸發安全分類器,系統會自動將任務切換到能力較低的模型,而不是直接傳回錯誤訊息。

公司預計,針對 Opus 5 的安全分類器觸發頻率將比 Fable 5 低約 85%。對 API 使用者而言,這意味著在更多請求中可以獲得可用回應,減少因安全攔截帶來的呼叫中斷。
