Openai axes sora video engine after burning $1m a day on 0.5% of chatgpt’s users

The curtain fell on OpenAI’s cinematic darling last week. Sora, the much-hyped text-to-video engine that once lured Disney into a nine-figure partnership, is being unplugged less than 15 months after its Valentine’s Day reveal. The reason isn’t espionage, data-harvesting or a secret safety meltdown; it’s a spreadsheet that refused to turn green.

Half a million users, one million daily dollars

Internal figures show Sora peaked at one million sign-ups after its December mobile launch, then flat-lined below 500 000 weekly actives. That is barely 0.5 % of ChatGPT’s 900-million-user congregation. Meanwhile, inference bills hovered around $1 million a day, driven by the voracious cost of 3-D tensor crunching and watermark-grade safety filters. The maths became a massacre: each 30-second clip consumed more compute than 10 000 ChatGPT prompts, yet users paid flat-pro fees that never covered the GPU rent.

Disney never wrote the rumoured billion-dollar cheque; it signed a memorandum that allowed its studios to test the tool, not bankroll it. When the marketing gloss wore off, no studio was willing to shoulder production-scale pricing that starts at $0.30 per second and scales exponentially with resolution.

Compute caravan turns to enterprise

OpenAI is now rerouting the 30 000 Nvidia H100s that kept Sora alive into an unannounced platform nicknamed Spud, people familiar with the plan say. Spud is not consumer candy; it is a multimodal API aimed at enterprise developers who will pay per token, per frame and per heartbeat. The pivot mirrors the wider race to monetise before an anticipated 2026 IPO and before Anthropic’s Claude-4 enterprise suite ships this autumn.

Sam Altman’s chatbot cash cow already funds a robotics division and a hush-hush consumer device designed by Jony Ive. Sora’s shutdown frees two scarce resources at once: silicon and storytelling bandwidth. In a town where narratives are monetised by the millisecond, continuing to bankroll a loss-making spectacle no longer passed the venture-capital laugh test.

The lesson? Even in the golden age of generative miracles, venture capital still speaks one language: unit economics. Sora could hallucinate galaxies, but it could not hallucinate profits. The reels are gone; the bill remains.
