(Yicai Global) April 11 -- Kunlun Tech's shares soared after the Chinese mobile games and social entertainment platform operator sent invitations to users for them to test its ChatGPT-like artificial intelligence language model Tiangong 3.5.

Kunlun Tech [SHE: 300418] ended 9.5 percent up at CNY45.76 (USD6.57) a share today, after surging by as much as 15.9 percent in the morning trading session, bringing the stock’s gain so far this year to 218 percent.

Users can now register to participate in Tiangong 3.5 testing on April 17 via a test website, the Beijing-based firm said late yesterday, without disclosing further details.

Tiangong 3.5 was co-developed by Kunlun Tech and Singularity AI, a Chinese developer of large-scale per-trained language models. The product's intellectual property rights belong to Singularity AI, while Kunlun Tech gets half of the net profit generated after its commercialization, the latter said in March.

Since US startup OpenAI launched ChatGPT, or Chat Generative Pre-Trained Transformer, last November, a number of Chinese tech giants have followed suit, announcing the development of similar products, with many seeing their shares soar. In March, Baidu's Ernie Bot became the first to open for testing.

ChatGPT is an AI technology-driven natural language processing bot that can interact with users by understanding and learning human language. It can write emails, create video scripts and copywrite, translate, code, and write papers, among other functions.
