第一段

原文

Large AI models can process not only text, images, and audio, but also integrate these multimodal data to form a comprehensive understanding and make inferences.
However, training such a model requires massive amounts of training data. Therefore,
we typically apply a pre-trained foundation model to daily tasks and fine-tune it based on the distinctions of each task.

第2段

原文

In the country, the demographic problems have attracted many experts.
They indicated that the population growth rate has declined by an average of 1% annually over the past five years, while the share of the older population has risen at a rate of 8% annually, because more and more young people are reluctant to marry before the age of 35.
The trend has caused significant societal risks, mainly including an accelerating aging population and a growing shortage of healthcare services.

The government estimates that by 2035, the share of the population aged 55 and older will rise to 28% of the country’s total population.
