Specialised data sets can make AI services more helpful to vulnerable users who increasingly rely on them for emotional support and health guidance, said Lu Shiyu of Tencent Research Institute (TRI). Since 2024, TRI has been developing specialised data sets with such groups in mind. In a typical cycle, LLMs receive general knowledge during pre-training from the internet and are fine-tuned in post-training before deployment. Last year, Lu's team and researchers from the University of Science and Technology Beijing tested leading US and Chinese LLMs, including Tencent's Hunyuan model, and found gaps in handling topics like sex education for China's 69 million left-behind children. The effort also yielded an elderly data set from thousands of Q&A samples. Lu said the next step is to partner with major AI model developers with large user bases.
