國產大模型Kimi帶動產業鏈革新,傳媒ETF、影視ETF大升

Kimi大模型引爆市場,影視、傳媒、遊戲板塊大升,華策影視、掌閲科技、中廣天擇升停,銀華基金影視ETF升超3.5%,國泰基金影視ETF、鵬華基金傳媒ETF、廣發基金傳媒ETF、華泰柏瑞基金遊戲動漫ETF、華夏基金遊戲ETF升超2.5%。

3月以來,國泰基金影視ETF、銀華基金影視ETF升15%,鵬華基金傳媒ETF、廣發基金傳媒ETF升超10%。

3月18日,月之暗面宣佈其AI產品kimi,在大模型長上下文窗口技術上取得新的突破,Kimi智能助手已支持200萬字超長無損上下文,並於即日起開啟產品內測。Kimi chat是月之暗面推出的對話助手工具,於2023年10月10日發佈,發佈之初即定位長文本。支持輸入20萬漢字,是目前國產大模型中支持的最長上下文輸入長度,2024年2月,kimi迭代了網站、多問題搜索能力,可用性繼續提升。3月,上下文能力達到200萬字。多次迭代後伴隨着Kimi用户活躍度提升,2月平均日活同比上升101.9%,3月前二週繼續攀升。

根據申萬宏源的內部測評,國產大模型Kimi文字能力全面達到GPT-4水平。Kimi中英文生成能力已經接近GPT-4水平,儘管邏輯推理能力仍有差距,且主打文字生成、目前無多模態能力;Cluade3中英文生成、理解、推理,多模態圖片理解能力均與GPT-4接近,效果好於Gemini,且實際使用中生成速度快於GPT-4和Gemini。

申萬宏源認為其在長文本單點能力上實現突破,精準定位辦公人羣。Kimi支持200萬漢字的長文本輸入,對比來看,GPT-4 Turbo-128k的能力是約10萬漢字,Claude3200k上下文是約16萬漢字。因此,Kimi更適用於高效閲讀、專業文件解讀、資料查詢、資料整理總結等方面。

興業證券表示,Kimi引領AI行情加速演繹,堅定看好AI應用未來發展,Kimi基於無損長上下文能力打造的核心功能主要集中在三個方面:

1.內容檢索:相較於傳統搜索引擎而言,Kimi能通過自研的引擎實現信息的精準搜索與相關度匹配,生成更加直接、準確的答案,並附帶內容鏈接,實現信息的高效蒐集、索引。

2.內容理解:在內容檢索的基礎上,Kimi能基於泛化內容形成有效的信息聚合與內容提煉,在代碼側亦能提供基礎的註解功能,高效賦能多元辦公場景。

3.內容生成:長無損上下文理解能力有望結合現有的中文語料庫、視頻庫進行垂類內容生成訓練,或將率先賦能短劇、短視頻、直播電商、教育、辦公等領域,未來隨着邏輯完善和算力改進,有望實現“從短到長”的突破。

Kimi的出現僅是近期AI產品落地的冰山一角,自2023年12月PIKA出圈以來,Gemma、Genie、Sora、Stable Diffusion 3等模型/產品已陸續湧現,我們堅定的認為,隨着AIGC技術的持續迭代,未來將會有更多AI爆款產品的出現,並持續驅動傳媒行情增長。
