OpenAI is shutting down its Sora video generation app and API

OpenAI is shutting down its Sora video generation app and API this month. For UK businesses, this marks the end of cheap, compute-heavy generative video and serves as a harsh lesson in relying on a single vendor. The consumer app closes on 26 April, with the developer API following in September.

OpenAI closes its flagship video platform

On 24 March, OpenAI confirmed it will discontinue Sora just six months after launching the standalone app. The platform allowed users to generate hyper-realistic video clips from text prompts, but it quickly became a financial and operational burden.

The company will shut down the web and mobile apps on 26 April 2026, and it will turn off the Sora API on 24 September 2026 March 2026 AI Roundup (https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQGx0LhZMnKlzchLYGwHuh46gZ_X9zL9_Ux6h1znUdh7FyvS3nS9HM5X76Jwjt4BXUY0vpqAB6jp0NazbZycH9dedBKtOmkuz-0Oab2q1c_f1qO10duYHyEaepAmYTO0Ej4c-h2gbEV8WJwBQyhjWW4TqXJOcXsicWeFC051ePz9Na8bjQs_SkFPEi4kRhyrfhQt8Q==). The decision also terminates a high-profile licensing partnership with Disney, which allowed users to generate content featuring licensed characters The Guardian (https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQHF6ZLLhKE7-iHn2-3g23IxRap14c7objFGFVf8vuAUNVuOCkctduul1KSUhre16w8eDS9B7Pe5RHdYNGupewkM57WZLX1VOHFDhE_rNrnCYyO_7TmIZJy5UwBtyJLhFubF9aL78Tk2Kno1YcBaRss42FuvTxvoLAGV5QAeQpzZJRIt).

Operating the service cost an estimated $1 million per day due to the massive computational demands of video generation. Alongside the compute costs, the platform struggled with severe content moderation issues. This prompted OpenAI to shift its resources back toward core enterprise tools and robotics research.

The hidden cost of compute-heavy marketing

The immediate takeaway is that generative media isn't a stable foundation for your marketing strategy. Video AI requires immense compute power, making it
