1 . ChatGPT, an artificial intelligence-driven chatbot (聊天机器人) programme that responds to user prompts, has gone viral in social networks in recent weeks.

There’s nothing ___________ in software that produces fluent and logical writing. ChatGPT’s predecessor (前身), the Generative Pretrained Transformer 3 (GPT-3), could do that too. Both were trained on an unimaginably large amount of data to answer questions in a/an ___________ way. But ChatGPT has been updated by being given the data on human “conversations”, which significantly ___________ the truthfulness and informativeness(信息准确性) of its answers.

___________, ChatGPT still produces answers that seem reasonable but are incorrect or nonsensical (无意义的). Even the chatbot itself says, “My responses are not intended to be considered as ___________.” This might be a big problem on the Internet, as many web platforms (平台) ___________ the ability to protect themselves against a flood of AI-generated content (AI生成的内容).

In the wrong hands, it could be a weapon to harm people and society.

No one knows what will happen to such technologies if the software engineers of the future will themselves be software programs. “Human supervision (监督) and ______________ are required,” OpenAI’s researchers have warned.
