OpenAI也減價 模型定價權轉向市場

OpenAI在8月下旬向開發者社群投下一枚震撼彈。這家ChatGPT的開發商宣布，將旗下所有面向開發者的前沿大模型GPT-5.6 Sol的價格下調超過20%，為期3個月。標準短上下文的使用價格降至每百萬輸入詞元（Token）收費4美元，每百萬輸出詞元收費20美元。相比之下，此前的價格分別為5美元和30美元，前者降幅20%，後者降幅達33.3%。 這已經不是OpenAI第一次動刀。7月底，該公司已對旗下較小的模型作出價格調整：中階模型GPT-5.6 Terra降價20%；低成本Luna模型更直接砍掉80%。從7月底到8月底，3周內完成兩輪降價，這種密集的調價頻率在OpenAI歷史上並不多見。 ...

2026年的市場，正在同時上演三齣戲：美元流動性枯竭、石油供應緊張，以及正在升溫的全球糧食危機。 太平洋迎來了150年來最強的聖嬰現象。印度氣溫飆破48°C，歐洲熱浪奪命，亞洲颱風與暴雨輪番上陣。但這場災難真正可怕的地方，不是天氣變熱，而是它打亂了全球的雨帶分布——該下雨的地方不下雨，不該下雨的地方暴雨成災。 於是我們看到一連串矛盾的景象： 全球玉米的主要產地美國，農田乾裂 ...

錢大媽上市之路再啟：3000店規模背後，為何資本市場冷眼旁觀？

「不賣隔夜肉」——這句響亮的口號讓錢大媽在中國生鮮零售市場迅速崛起，成為社區生鮮連鎖的代名詞。然而，當這家擁有逾3,000家門店的巨頭再度向港交所遞交上市申請時，市場的反應卻異常冷淡。 年初首次申請失利後，錢大媽選擇捲土重來。但問題是：如今的港股氛圍已與年初大相逕庭。縱使是AI大模型、芯片等市場寵兒，股價亦已從高位腰斬，更何況錢大媽這類傳統連鎖產業？在業績停滯、擴張受阻、毛利率低迷的多重陰影下，這次IPO究竟是價值投資的機會，還是另一個需要謹慎迴避的陷阱？ ...
