OpenAI discontinues Sora, marking the first major product shutdown by a frontier AI lab

事件摘要

On April 26, 2026, OpenAI discontinued Sora, its text-to-video generation tool, shutting down both the web and app experiences. The shutdown came just over two years after Sora's spectacular February 2024 preview, which had been hailed as a breakthrough in AI video generation. OpenAI cited the high cost of video generation inference, limited product-market fit, and the emergence of more cost-effective competitors (Google's Veo 3, open-source alternatives) as factors. Sora became the first high-profile product casualty of the AI industry's intensifying cost and competition pressures.
