Anthropic被曝將推Sonnet 5.5，內部代號Fennec（沙漠狐），或下月發佈。支持最高200萬token上下文，推理速度快、延遲低，長上下文推理及多步規劃顯著提升，瀏覽器/終端工具調用增強。性能直逼旗艦Claude Fable 5，但維持Sonnet定價，打造性價比之王。
Anthropic新一代編程大模型Claude Sonnet5（代號Fennec）意外泄露，現身谷歌雲基礎設施，預計2026年2月初發布。該模型性能強大，被形容爲“把整個開發團隊塞進模型裏”，標誌着編程AI進入新階段。泄露源於API調用時觸發的404錯誤日誌，顯示模型已基本完成。
Anthropic即將發佈新一代AI編程模型Claude Sonnet5，性能大幅超越現有旗艦模型，價格卻降低一半。它採用創新的“蜂羣”開發模式，旨在解決當前編程AI的痛點，有望重塑行業格局。
