Asia Tech Wire (Apr 24) -- Shares of Chinese artificial intelligence firm SenseTime Group (0020.HK) have soared after launching its latest model that rivals OpenAI's GPT-4 Turbo generation model.

SenseTime on Tuesday launched the SenseNova 5.0, the fifth-generation version of its large model SenseNova.

The model utilizes the Mixture of Experts (MoE) architecture and is based on over 10TB tokens of training data, enabling effective context window coverage of approximately 200,000 during inference.

"This update primarily focuses on gathering enhanced knowledge, math, reasoning and coding capabilities that fully benchmark the GPT-4 Turbo, meeting or exceeding the GPT-4 Turbo on mainstream objective reviews," SenseTime said in a press release.

SenseNova 5.0 supports the parsing and comprehension of high-definition long-form diagrams and the interactive text-to-image generation, as well as complex cross-document knowledge extraction and summarized Q&A presentations, the company said.

SenseTime Chairman and CEO Xu Li also demonstrated the company's text-to-video capabilities at the event and said it would be releasing a text-to-video platform in a very short time.

SenseTime halted trading in its Hong Kong-listed shares on Wednesday morning, up 31.15% before the suspension.

In response to the suspension of trading, SenseTime said, "In accordance with the listing rules and the recommendations of the Hong Kong Stock Exchange, the company will make further announcements."
