Notes

行動裝置(iOS/App/平板)支援情況尚待逐一核實,目前僅列網頁版。官網(api-docs.deepseek.com)標示舊版模型名稱 deepseek-chat/deepseek-reasoner 已於 2026/7/24 起棄用,改對應 DeepSeek-V4-Flash 的一般/思考模式,使用舊模型名的API使用者需留意。2026-07-27新增觀察項目:多篇媒體(SCMP/winbuzzer.com/thenextweb.com)報導DeepSeek預告將對V4新增尖峰時段(北京時間9am-中午、下午2-6pm)加倍收費機制,但截至本次查核官方定價頁仍為單一費率、未見加價條款文字,此為預告尚未上線,非本站資料有誤,持續追蹤。
