Sand AI, a China-based startup developing video-generation models, said on November 5 it raised US$200 million in a series A+ round led by Cornerstone Capital and Wangsu Science & Technology.

The company said it will use the funds for model research, computing infrastructure, product upgrades, and overseas expansion.

Sand AI said the round brings its total funding over the past 10 months to US$300 million.

It added that it plans to work with Wangsu on enterprise deployment of its video models.

Wangsu, a Chinese cloud and network infrastructure provider, had previously disclosed plans to invest 300 million yuan (US$45 million) in Sand AI.

The arrangement includes convertible bonds and warrants, along with cooperation on computing, networking, and security for audio and video inference.

In unaudited figures in Wangsu’s filing, Sand AI Group recorded 17.4 million yuan (US$2.61 million) in revenue in the first half of 2026 and a net loss of about 152 million yuan (US$22.8 million).

Separately, China has adopted labeling rules for AI-generated synthetic content, and non-compliance can lead to suspension or penalties.
