OpenAI has announced the discontinuation of its AI-powered video platform Sora, launched in December 2024 and released as a standalone app in September 2025. Despite an initial surge of over one million downloads within five days, Sora is being shut down due to high operational costs, declining user engagement, regulatory challenges, and a strategic shift toward more profitable ventures. Disney, which recently invested $1 billion in Sora, will retain its investment but will abandon joint projects. The app and web version will cease operations on April 26, 2026, with the API ending on September 24, 2026.
