UNISOUND (09678) experienced a significant surge of over 9% during the late trading session. At the time of writing, the stock was up 4.31%, trading at HKD 280.6, with a turnover of HKD 208 million. The movement follows the company's recent announcement of the official launch of its document intelligence foundation model, "Unisound U1-OCR." As the first industrial-grade document intelligence base, this model ushers in the era of OCR 3.0. Building on layout understanding, it further gains insight into the deep semantics of documents, enabling automatic classification and business-level information extraction. This represents a leap from merely "recognizing text" to "understanding documents." Public information indicates that U1-OCR has achieved state-of-the-art (SOTA) performance in multiple authoritative tests, demonstrating significant core competitiveness.
