由 DeepSeek-V4 與 R1 驅動的高效開源權重與託管推理 AI,token 成本極低。
依託稀疏混合專家架構(V4-Pro 為 1.6T 中的 49B 啟用參數),以極低延遲與記憶體開銷處理最多 100 萬 token。
由 DeepSeek-R1 開創並融入 V3.2 與 V4 思考模式,對複雜數學、邏輯與程式碼除錯展示逐步自驗證過程。
快取命中時,輸入 token 成本降至 Flash 的每百萬 0.003 美元與 V4-Pro 的每百萬 0.022 美元,離峰 UTC 時段費率再低 50%。
在 chat.deepseek.com 及 iOS/Android 上免費提供文件上傳、推理模式與網頁搜尋,核心模型無須付費牆。

從附頁碼引用的資料出發展稿,並審查文件的學術誠信
ChatPDF 工具依據檢索到的原文片段回答論文問題,並逐字校驗引用,讓回答始終對應到具體頁面。
把已確認的大綱與選定證據變成草稿,可續寫的工作空間讓引文一路傳遞,而不會盲目貼上。
每條結論都必須逐字引用你的文件,摘錄找不到即被丟棄,因此每個標記都能被你實際核查。
AI Detector 提供可檢視的審查訊號,而非單一黑箱百分比,並定位為輔助證據。

提供巨大的上下文視窗與深度的 Google 生態系整合,但對於純推理任務感覺較不夠專精。
