UNISOUND (09678) surged nearly 19% again, accumulating a gain of almost 90% over the past four trading sessions. As of the time of writing, the stock was up 16.75%, trading at HK$416.8, with a turnover of HK$469 million. The surge follows the company's recent announcement projecting its large model-related business revenue for 2025 to reach approximately RMB 600 million to RMB 620 million, representing a staggering year-on-year increase of about 1057% to 1095% compared to 2024. This explosive业绩增长 is attributed to the company's leading core technological capabilities in large models and an accelerated pace of commercial implementation. Notably, UNISOUND recently officially launched the "Shanhai Zhiyin" large model version 2.0, marking the completion of a crucial piece in the company's "One Foundation, Two Wings" technology strategy. Leveraging the "Shanhai Atlas" intelligent computing base, the new version reshapes voice interaction logic through an end-to-end architecture, signaling a transition for AI voice interaction from merely "understanding commands" to a new stage of "empathetic conversation."
