OpenAI announced the shutdown of Sora, its video-generation social app, in a post on X saying "We're saying goodbye to Sora," less than six months after its launch on September 30, 2025. A two-stage timeline followed: the app and web version would close on April 26, 2026, and the Sora API on September 24, 2026, with users urged to download their content before the cutoff dates. Media reported that high inference costs far outweighed revenue while active users declined; OpenAI said it would reallocate compute toward coding and enterprise products, continuing video generation as world-model research.
