ShengShu raises over RMB 600 million in Series A+
ShengShu Technology, the Chinese developer of the Vidu video-generation models, has closed a Series A+ round of more than RMB 600 million to expand its multimodal foundation model work.
ShengShu Technology announced that it has closed a Series A+ round of more than RMB 600 million. The company says it will use multimodal foundation models to change AI productivity across "digital and physical worlds." The material provided does not name investors, give a valuation or say how the money will be spent, and it does not explain what the physical-world work involves.
Most of the announcement recaps ShengShu's past releases. The company says its team introduced the U-ViT architecture in September 2022. It launched Vidu globally in July 2024 with what it calls the industry's first Reference-to-Video feature, which aims to keep several characters or objects consistent across a generated clip. Vidu Q1, Q2 and Q3 followed.
ShengShu calls Vidu Q3 the first video model built for storytelling. It can generate 16 seconds of video with synchronized audio at native 1080p, and the company says it handles shot transitions and text rendering in several languages. ShengShu cites Artificial Analysis rankings that place Q3 first in China and second worldwide. It also says Artificial Analysis data shows Vidu Q2 is the fastest-generating commercial-grade content model.
In December 2025, the company open-sourced TurboDiffusion. ShengShu says the framework generates a 5-second video in 1.9 seconds on a single RTX 5090 GPU, which it describes as 100 to 200 times more efficient.
