Why OpenAI Really Shut Down Sora
OpenAI’s decision to shut down its Sora AI video generator was not entirely shocking. The company had previously signaled plans to fold the Sora app into ChatGPT, though the speed of the move caught me off guard. What made the timing more curious was that OpenAI was reportedly holding meetings with Disney about the app as it was releasing the announcement. So what drove the sudden decision?
My bet is cost.
Generating a short Sora video is surprisingly expensive. A typical three-second clip likely ran OpenAI somewhere between $0.50 and $2.00 in raw compute, and potentially more depending on resolution and scene complexity. Video generation is not simply an extension of text or image AI. It requires rendering hundreds of coherent frames while maintaining temporal consistency, often across multiple diffusion passes. Under the hood, that translates into serious GPU demand. Estimates suggest producing one minute of video can require roughly 12 minutes of high-end GPU time, which still adds up to tens of seconds of compute even for a short few second clip. Factor in the cost of premium hardware like NVIDIA H100s and the sheer volume of floating point operations involved, and the economics deteriorate quickly.
The numbers at scale were brutal. Sora was reportedly generating somewhere between 10 - 11 million videos per day at peak usage. At a cost of $1.50 per video, that works out to roughly $450 million per month in compute costs alone. Sora never had a dedicated subscription program. Paying OpenAI users simply received preferred access as part of their existing plan, which made the unit economics nearly impossible to justify.
We will likely never see the actual figures, but my read is that Sora was an ambitious and very costly experiment, and OpenAI decided the math just did not work.
