Kling 3.0 adds native 4K; Sora compute costs climb
- Kling AI said its VIDEO 3.0 series now offers one-click native 4K output, pushing full-resolution generation into a market still dominated by 1080p workflows. - Kling said the new mode preserves reference consistency and costs 30 credits per second, framing 4K as a production feature, not just marketing. - Sora’s March shutdown showed video costs can still overwhelm adoption and revenue.

AI video models turn text into moving images by predicting one frame after another, then stitching those frames into a clip. Higher resolution means many more pixels per frame, so cost rises fast when tools move from 1080p to 4K. (kling.ai) (techcrunch.com) Kling AI said this week that native 4K output is now available in its VIDEO 3.0 series. The company described it as one-click 4K generation with sharper detail and no need for post-production upscaling. (kling.ai) Kling said the 4K mode is aimed at large-screen playback, high-definition delivery, and professional production workflows. It also said the model keeps reference consistency during 4K generation, preserving color, lighting, style, and subject features. (kling.ai) The pricing detail matters as much as the spec sheet. Kling said native 4K generation costs 30 credits per second, which turns resolution into a budgeting question for creators making longer clips. (kling.ai) That cost pressure helps explain what happened to Sora. OpenAI shut down its consumer video app in March 2026 after usage fell from about 1 million users to fewer than 500,000, according to reporting summarized by TechCrunch from The Wall Street Journal. (techcrunch.com) TechCrunch reported that Sora was costing OpenAI roughly $1 million a day to run, while the company redirected chips and staff toward products with stronger business demand. The same report said Disney learned less than an hour before the shutdown that a planned $1 billion partnership was dead. (techcrunch.com) Some later commentary put Sora’s peak inference burn far higher, at about $15 million a day annualized, citing Forbes estimates from late 2025. That figure is not the one in the Wall Street Journal account summarized by TechCrunch, but both versions point to the same constraint: video generation consumes expensive compute. (forbes.com.au) (techcrunch.com) Kling’s 4K launch lands in that gap between what creators want and what providers can afford to serve. The product pitch is cinematic output at full resolution; the business test is whether enough users will pay for every extra second. (kling.ai) (techcrunch.com)
