Shares of Unisound AI Technology soared after the Chinese artificial intelligence company guided for revenue from its large language model business to rise by more than tenfold.
The stock surged 55% on Wednesday in Hong Kong, and is on track for its largest single-day gain ever.
The Beijing-based company said it expects total revenue from large model-related business for 2025 to rise by over 1,000%, which it attributed to its leading position in core technological capabilities and progress in commercializing the technology, according to a filing on Wednesday.
The LLM business currently accounts for around half of the company's revenue, Unisound added.
Unisound specializes in developing AI voice technology, using its UniGPT models to create multiple types of AI agents that can cover a range of typical business scenarios.
The company has struck partnerships with Chinese companies including JD.com, Huawei and Ping An Group, integrating its products into sectors including healthcare, insurance and transportation.
Investor enthusiasm around Chinese AI companies has exploded following homegrown AI developer DeepSeek's breakthrough a year ago. Since then, stocks of Chinese technology majors have rallied, while listings by AI startups, such as MiniMax's debut earlier this month, have been met with strong market responses.
Beijing has issued directives to accelerate the rollout of AI applications and make achieving technological self-reliance a priority.
