OpenAI kills Sora: $15M/day peak inference, 2% seven-day retention, $2.1M lifetime revenue.
Story
Sora's web experience was discontinued April 26 with API sunset September 24. The economics are staggering. Peak cost: $15M per day. Total in-app purchases over six months: $2.1M. The product peaked at ~1M users, then collapsed below 500K. This is the first time a frontier lab has killed a flagship consumer product this decisively. Video generation's unit economics are broken at current compute costs.
