(Yicai) Feb. 19 -- Chinese artificial intelligence stocks soared by their daily limit on the first trading day after the lunar new year holiday in the wake of OpenAI launching Sora, an AI model that creates realistic and imaginative scenes from text inputs.

Insight Brand Marketing Group [SHE: 300781], Wondershare Technology Group [SHE: 300624], Guomai Culture & Media [SHE: 301052], and Easy Click Worldwide Network Tech [SHE: 301171] climbed 20 percent in Shenzhen today. Keda Technology [SHA: 603660] added 10 percent in Shanghai, while Arcvideo Technology [SHA: 688039] jumped 20 percent.

OpenAI released Sora on Feb. 15, with the tool attracting huge market attention for its ability to generate realistic 60-second videos in high definition based on short text instructions. Breakthroughs in multimodal large language models such as Sora will likely spark changes in the film and television industry, according to a research report by Soochow Securities.

Insight's AI-generated content team will start developing a text-to-video function next month and put it into public testing when the time is right, an employee told Yicai. The technology is new, and it is not yet known what changes it will bring to the marketing industry and how it will impact the company's business, the person noted.

Arcvideo is developing a text-to-video model similar to Sora to generate videos shorter than a minute, targeting business clients, The Paper reported, citing the video solutions and video cloud services provider. The firm has technical resources in video generating, compression, editing, and recognition, it added.

Video software developer Wondershare released its multimedia model Tianmu on Jan. 30, which can generate a video from a story summary, while book publisher Guomai said it is smoothly developing an AI comics model, and the company will make animated movies, miniseries, and interactive comics.

Easy Click's AI e-commerce video advertising tool, which is in close beta testing, can achieve 10 times the production efficiency of other advertising materials, the intelligent marketing services provider noted in a survey last August.
