Kuaishou’s Kling 4.0 targets 30-second video clips
Published by AINave Editorial • Reviewed by Ramit
Kuaishou’s AI video unit Kling has unveiled Kling 4.0, which can generate clips up to 30 seconds long. That longer format is the clear headline, but the model is not yet described as broadly available: Kling says a lite version is available to annual subscribers, with a full release planned for October. The announcement arrives as Chinese AI video companies compete with ByteDance for users and revenue.
Longer clips, limited access so far
A 30-second ceiling gives Kling’s model room for more continuous video than a short clip, but the reporting does not establish how the model performs across that duration or what other capabilities it adds. The practical distinction today is access: subscribers on annual plans can use the lite version, while the full release remains a plan rather than a confirmed launch.
That makes it premature to treat the announced duration as evidence of a finished production workflow. For teams assessing video generation, the reported maximum length says something about the intended output, but not about consistency, quality, or the effort needed to get a usable result.
A potential listing does not mean Kuaishou gives up control
The model launch comes amid reported fundraising and possible listing plans. Kling reportedly raised US$2.8 billion in July at a valuation of about US$18 billion, and Kuaishou still holds a majority stake. The reporting describes a potential Hong Kong spin-off, not a confirmed IPO or timetable.
A listing could remain possible even if Kuaishou keeps control, provided Kling operates independently with separate governance, according to the account of Hong Kong rules. That distinction matters: a public listing would not necessarily mean the parent had handed over control of the business.
Revenue is substantial, but inference shapes the business
Kling’s annualized revenue topped US$500 million in March. Annualized revenue is a run-rate measure, not a claim that the company earned that amount over a completed year. The figure signals commercial activity, but does not reveal Kling’s margins or the cost of generating each video.
That cost is central to the business. Industry analysis cited in the report says GPU inference can constrain margins, leaving providers to consider higher prices, limits on quality or duration, or cheaper computing power. Those are industry-level pressures, not disclosed Kling-specific cost figures.
The 30-second capability therefore has two sides: it expands the announced output length, while video generation’s computing demands put pressure on the economics of delivering that output. Whether Kling can turn the longer format into durable revenue depends on costs the available reporting does not quantify.
