Sora 2 vs Veo 3 vs Keling actual measurement comparison, how to choose the top three AI video generators in 2026

Sora 2 vs Veo 3 vs Ke Ling Actual comparison, how to choose the top three AI video generators in 2026

AI video is still a gimmick at the end of 2024, and most of the output looks like low-resolution dream fragments. By the end of 2025, Sora 2 is in public testing, Google Veo 3 is integrated into Gemini, and Keling AI has leapt to the first echelon of domestic video generation. The entire track's image quality, dynamic stability and command understanding capabilities have simultaneously crossed the threshold of "commercial use". This is one of the most important product nodes in the past two years. Looking back ten years from now, it may be a critical point for the video content industry.

This article puts the three companies under the same set of prompt words for actual measurement and comparison, starting from several dimensions: image quality, motion consistency, command understanding, Vincent lens capabilities, price, and commercial terms. All judgments are based on public test samples and official public page information, and do not reference undisclosed internal benchmarks.

Fundamental differences in the positioning of the three companies

Sora 2 was launched by OpenAI and is positioned as a video generation platform for general consumers and creators. It emphasizes the cinematic feel and long-shot continuity and is mainly targeted at short video creators, advertisers, and marketing teams. Veo 3 was launched by Google DeepMind and is deeply bound to the Gemini platform. Its advantages lie in its connection with the Google Workspace ecosystem and its accurate simulation of real physical laws. Keling AI is developed by Kuaishou, has stable performance in Chinese scenarios, is affordable and leads the domestic market share.

After understanding the differences in the positioning of the three companies, the selection logic becomes clear: choose Sora if you want to make content for the European and American markets, choose Veo if you need to embed it into Google workflow, and choose Keling if you want to make Chinese short videos or have major customers in China. This is the general direction, there are more differences in specific subdivision scenarios.

Image quality comparison

The same prompt word was given to three companies respectively, and they were asked to generate a five-second city night scene. The picture output by Sora 2 has the strongest sense of atmosphere, with delicate light and shadow levels, obvious advertising-level lens texture, and the details of the neon reflection on the street on the wet ground are quite realistic. Veo 3 has the cleanest picture, solid physical details, and the trajectory of raindrops on the umbrella is consistent with real physics, but the artistry is slightly weaker. Ke Ling's Chinese cultural elements are presented in the most natural way, and the Chinese characters on the signboard will not appear with common garbled characters.

For creators who pursue a cinematic feel, Sora is a more surprising choice; for those who want their videos to "look real", especially product demonstrations and teaching scenes, Veo's compliance with physical laws is more stable; for Chinese street scenes, characters, and scenes, Kelin's localization advantages directly translate into saved modification time.

Instruction comprehension ability

Complex instructions are a hard indicator to test video generation capabilities. The prompt words used for the test are: an orange tabby cat jumps over an open hardcover book on a wooden desk. The camera follows the movement of the cat and zooms in from right to left. The book is flipped by the wind, and the sunset light shines outside the window. This sentence contains four levels: subject, movement, lens language, and ambient light.

Sora 2 can fully present the lens following and light direction, and the detail of a book being flipped by the wind is also retained. Veo 3 is more precise in the subject's movements. The cat's jumping posture is natural, but the lens movement is slightly smaller. It can complete the subject's movements and ambient light, but the lens will occasionally ignore the more professional instructions such as following. Overall, Sora 2 has the deepest understanding of movie language, Veo 3 has the most accurate understanding of object behavior, and Keling is the most direct in semantic analysis of Chinese commands.

Duration and resolution

As of the time of writing this article, the public version of Sora 2 supports single-segment generation within twenty seconds by default. The specific upper limit is subject to the official public page. The duration of a single segment supported by Veo 3 is close to one minute, but the complete duration will be split into multiple shots, generated separately and then spliced ​​together. Keling supports ten seconds to thirty seconds in domestic paid files, and can be spliced ​​into longer videos through the continuation function.

In terms of resolution, all three support 1080p output, Sora 2 premium subscription supports 4K, and Veo 3 can output 4K through the Google backend. Corin's high-resolution files also require a higher subscription. If it is a vertical short video scene such as Douyin, Xiaohongshu, and Instagram Reels, 1080p is enough, and there is no need to pay more for 4K.

price comparison

Please refer to the official public page for price details. Only the differences in pricing models are described here. Sora 2 is bundled with the ChatGPT package. Plus users have a certain monthly generation quota, and Pro users have a significantly increased quota. Veo 3 has a smaller quota in the Gemini personal version, and full capabilities require a subscription to the Google AI Premium version. Keling AI focuses on more detailed pay-per-view or monthly billing, with multiple price ranges, suitable for flexible selection based on demand.

If you only occasionally generate a few articles, Keling's pay-per-view is the most cost-effective; if you are a content studio that produces stable volume every week, Sora or Veo's subscription file is more economical; if the team is already using Google Workspace, integrating Veo into Workspace will provide the smoothest experience.

Differences in commercial terms

Commercial use is the core of corporate decision-making. Sora 2 states in the subscription agreement that paying users have the ownership of the generated content and can use it commercially, but OpenAI retains training and promotional purposes. The commercial license of Veo 3 needs to confirm whether it is an individual user or an enterprise user. The specific terms are subject to the Google AI Terms of Service. The domestic paid version of Keling AI clearly supports commercial use, but the user agreement requires compliance with platform review rules, and there are additional review processes for content involving character images and brand logos.

Particular attention should be paid to cross-border content creation. If the same AI video is released on domestic and overseas platforms at the same time, it needs to meet the compliance requirements of both platforms and the service terms of the source model. It is recommended that the legal department review this paragraph first, so as not to find it too troublesome.

speed and stability

In actual production, the generation speed is also very important. Sora 2 has a longer waiting time during peak periods, Veo 3 is generally stable in the Google service cluster, and Keling's waiting time is among the first in the country. From submission to getting the result of a 5-second video, all three companies can control it between two and five minutes during off-peak hours, with little difference.

But the failure rates vary. Sora 2 will occasionally refuse to generate content due to strict content review. Triggering keywords include obvious celebrity names, brand names, and political content. Veo 3 is similar but has slightly less range. Keling's domestic review is more focused on Chinese sensitive words, and accidental damage mainly occurs on historical figures and geographical topics. These are not quality issues, but compliance design differences, which should be considered based on the subject matter when selecting.

Three typical selection suggestions

If you are an independent creator making short video content, I recommend Sora 2. The lens quality and creative expression are the core competitiveness, and it is worth paying for the cinematic feel. If the corporate marketing department is making product demonstration videos or teaching content, Veo 3 is recommended. The realism of physical laws and the connection with the Google ecosystem reduce the total cost of production and distribution. If you are doing Chinese short video e-commerce, local brand content, and Douyin Kuaishou, I recommend Keling. It has low price, clear compliance, and fast picture production speed. The three advantages combined make it very powerful in the domestic market.

Mixing and matching is also a trend. Many studios use Sora for main shots, Veo for close-ups, and Keling for Chinese subtitles, each drawing on its own strengths. AI video does not require a huge one-time investment like traditional video shooting, and the cost of trial and error is low. It is worth spending a week or two to use each one to find the one that best suits your business.

FAQ

Can Sora 2 be used in China?

A ChatGPT Plus or Pro subscription is required, as well as a network environment with stable access to OpenAI services. Domestic users usually use overseas identity and payment channels for compliance. The specific compliance boundaries are subject to the official service terms. This article does not provide any suggestions for ways to bypass official restrictions.

How to access Veo 3

Veo 3 is accessed through the Gemini application, Google AI Studio or Workspace backend, and requires a Google account. Some functions are not available in mainland China. The specific available areas are subject to announcement on the official Google AI page.

Which one is better, Ke Ling or Ji Meng?

Both companies belong to the first echelon in the country, each with its own focus. Ke Ling is slightly stronger in camera movement and long shot coherence, while Ji Meng is better in creative scenes and short shot explosive power. Both have a lot of free quotas. It is recommended to try the same set of prompt words separately and choose the one that is more pleasing to you and continue to pay.

Can the generated video be directly used on Douyin?

Yes, but there are three things to note. The first is the platform’s labeling requirements for AI-generated content. Currently, most platforms require AI content to indicate the source; the second is compliance review, and videos involving real people, brands, and sensitive topics require extra attention; the third is video specifications. The vertical version of 9:16 is Douyin’s preferred choice. This ratio is directly selected when generating to avoid loss of image quality during later cropping.

Will the three companies merge in the future?

Not in the short term. Sora 2 has a cinematic feel, Veo 3 has a physical reality, and can be localized. Each company has a foothold in different market segments. From the perspective of product evolution, the three companies will deepen their respective strengths rather than converge with each other. The benefit that users can enjoy is that there are different choices for the same type of subject matter, and differentiated competition drives the entire track forward.

The threshold for AI video generation has changed from "being able to shoot videos" which originally required ten years of work, to "being able to write prompt words" which now requires three days of proficiency. The impact of this change goes far beyond the content industry. Marketing, education, e-commerce, and early film and television development will all be redefined.
