刚刚，OpenAI宣布关闭Sora

Core Viewpoint - OpenAI has announced the closure of its Sora application, citing the need to focus resources on next-generation models due to Sora's inability to achieve profitability and declining user retention rates [1][4][8]. Group 1: Reasons for Closure - Sora's download numbers have been consistently declining, indicating a lack of sustained user interest [2][4]. - The application had a 30-day retention rate of only 1% and a 60-day retention rate of 0%, suggesting that while users may have been initially interested, they did not continue to engage with the product [7]. - The operational costs for Sora were extremely high, reportedly around $15 million per day, translating to approximately $5.5 billion annually [7][10]. Group 2: Strategic Shift - OpenAI is reallocating resources from Sora to focus on more promising areas such as reasoning capabilities, programming tools, and enterprise-level solutions [8][12]. - The company is prioritizing the development of its next flagship model, codenamed Spud, which is already in the pre-training phase [9][12]. - The closure of Sora is seen as part of a broader strategic shift towards world models and long-term applications in embodied intelligence, particularly in robotics [12]. Group 3: Impact on Partnerships - The closure of Sora has significant implications for OpenAI's partnership with Disney, which had invested $1 billion and signed a three-year agreement to license over 200 IP characters for Sora [4][19]. - Following the announcement, Disney has decided to withdraw from the partnership, indicating potential challenges for OpenAI in securing future collaborations [19].
