Anthropic宣布新一代Claude 3.5 Haiku模型因效能提升、價格也調漲4倍,有用戶指出Haiku雖然和GPT4o-mini的標竿測試表現不分軒輊,但價格是GPT4o-mini的7倍,也比Gemini 1.5 Flash更貴

Anthropic本周宣布最新版小模型Claude 3.5 Haiku價格調漲4倍,其漲幅與說詞引發用戶反感。

Haiku是Claude系列中最小的語言模型。10月底,Anthropic公布Claude 3.5 Sonnet(Sonnet為介於Haiku和Opus之間的中型模型)和Haiku的功能。本周該公司宣布Claude 3.5 Haiku正式上線,不過目前只支援文字輸入。用戶可以透過APIAmazon Bedrock和Google Cloud的Vertex AI存取該模型。

Anthropic指出,Haiku速度快,用於寫程式特別強大。在一項以標竿資料集SWE-bench Verified進行的測試中,效能超過現有市面上state-of-art模型,包括GPT-4o,另外,在最終測試中,Haiku在多項標竿測試中,效能超越前一代最大的模型Claude 3 Opus,卻只要極小比例的價格。因此Anthropic決定要調漲Claude 3.5 Haiku的價格,以反映「智能提升」。

最新價格為輸入字詞每百萬1美元起跳,輸出字詞每百萬5美元起跳,是原有價格的4倍。但該公司說,透過提示快取(prompt cache)及Message Batches API,用戶最高可省下90%的支出。同時Anthropic承諾仍將繼續提供Claude 3 Haiku,以滿足需要輸入圖像的任務,或是偏好低價的用戶。

不過Anthropic以「變聰明」漲價的理由引發用戶不滿。一名用戶表示,雖然在測試中Haiku和GPT4o-mini效能表現差不多,但是價格卻是後者7倍,也比Gemini 1.5 Flash更貴。另一名用戶說,「變聰明而漲價」的說法會惹毛許多模型愛用者。還有用戶直指,明白說維護和開發AI需要成本的說法還比較令人容易接受。

一名用戶指出,Haiku調漲價格將削弱產品吸引力,對品牌及營收都有害無利,用戶現在已經準備跳槽到競爭模型。

目前GPT-4o和Gemini 1.5 Flash的價格是每百萬字詞輸入0.15美元,而漲價後的Haiku是同業的將近7倍。相較之下,剛獲得66億美元增資的OpenAI則從去年以來,數度調降模型費用。上周OpenAI還宣布即時擬真AI語音的Realtime API,其提示快取文字輸入(cached text input)降價50%。
