As of midday, Hong Kong stocks continued to be under pressure, with the Hang Seng Index down 1.45% and the Heng Seng Technology Index down 1.51%. Individual stocks showed mixed performance, with Kuaishou (01024) rising against the market in midday trading, up 1.26% at noon.

Recently, the domestic video-based large-scale model, Kuaishou's 'Keling', was officially released, as the first Sora-level large-scale video-based model open to users, which has aroused high attention at home and abroad.

Recently, Tianfeng Securities released a research report stating that the Keling model fully benchmarked Sora, modeled complex spatial movements based on the 3D VAE mechanism and DiT model, generated videos that better conform to the laws of motion, and was capable of generating videos of higher quality and frame rates. In terms of the freedom of output video, the content length of up to 120 seconds far exceeds Sora's 60-second length, reaching the popular length of short videos. Testing has shown that generating a 5-second video only takes three minutes.

Currently, Kuaishou has launched a comprehensive layout in the field of AI, successively releasing the large-scale general language model 'Kuaiyi' with a parameter scale of 175 billion and the document-based graph large-scale model product 'Ketu'. The launch of 'Keling' signifies Kuaishou's leading position in the document-based video field. At the same time, Kuaishou has also launched video key technologies such as Direct-a-Video, Video-LaVIT, I2V-Adapter, and UNIAA, which have attracted widespread attention.

Guotai Junan Internet and Media Research pointed out that the Keling large-scale model has built an efficient large-scale automated data solution, covering many aspects such as massive video mining, multi-dimensional labeling and screening, video description enhancement, and data-driven effect quality evaluation. It is at the forefront of domestic large-scale video-based model generation.

Tianfeng Securities believes that the platform, Kuaishou, on which Keling's large-scale model is being tested is currently a head video editing software in China, and this feature is expected to drive daily active users in the short term. Leveraging the synergy between tool software and ecology through the short video platform, AI tool editing software is emerging. Data shows that the number of people queuing for Keling's internal testing qualification has exceeded 50,000.
