OpenAI has announced abrupt plans to shut down its AI video generator Sora, telling users it is “saying goodbye” to the app just six months after the launch of its stand‑alone platform that briefly propelled the tool into the mainstream. “We’re saying goodbye to the Sora app,” the company wrote in a post on X under @soraofficialapp. “To everyone who created with Sora, shared it, and built community around it: thank you. What you made with Sora mattered, and we know this news is disappointing."
