After opening the invitation system, iOS had 1 million downloads in the first week, and Android had 470,000 downloads on the first day, quickly reaching the top of the App Store free chart.

According to the latest data from SensorTower, the 30-day retention rate is less than 1%, and the 60-day retention rate is nearly 0%, far below TikTok's 48% level.

The qualified video rate is only 5%-10%, and users need to generate an average of 10 videos to get one usable material; the waiting time for rendering and failure rate have caused users to criticize the experience as "like being in prison."

OpenAI pays about $15 million per day for Sora2's computing power, totaling nearly $5.5 billion a year, but the paid penetration rate cannot cover the huge costs. The lack of basic interactions such as editing, pausing, commenting, and saving, along with a confusing community recommendation logic, leads to high-quality content not getting exposure, and the product has been criticized by users as "not even a toy."

The Cameos feature was sued for trademark infringement, content review policies have been repeatedly tightened, and the types of content that can be generated have continued to shrink, further reducing its practicality.

Executives publicly admitted that the model is "unsustainable," and the market generally believes that "technological advancement does not equal product success." From viral popularity to a cold snap in just two months, Sora2 has sounded a warning for the entire AI video generation industry: behind the computing power frenzy, user retention, cost, and business models remain unsolved challenges.
