ChatGPT is back in the headlines（新闻头条）! OpenAI, the company behind the popular chatbot, has now introduced a powerful new language model: GPT-4.

On March 14, GPT-4 showed the world how smarter it is than the previous GPT-3.5. One of its best new features（特点）is that it can understand pictures. For example, if you show a picture of a phone using the wrong charger（充电器）, GPT-4 can tell why the picture looks strange or funny.

But GPT-4’s developments don’t stop there. The new language model can code（用代码编写）classic games like Tetris（俄罗斯方块）in few minutes, and produce the code and layout（布局）for a website based on a hand-made drawing. It can also change the tone（语气）and style based on what you ask it to do. GPT-4 is much better than the older GPT at passing tests, which may worry teachers. According to CNN, GPT-4 did really well on a law school test, with a score in the top 10 percent of test takers. But GPT-3.5 only got a score in the bottom 10 percent.

GPT-4 will also power other apps and services. For example, the language learning app Duolingo plans to use GPT-4 in their upcoming（即将到来的）Duolingo Max function（功能）. Users can learn language by talking with AI. Another app, Be My Eyes, will have a digital assistant（数字助手）to help blind people better understand the world around them. The government of Iceland also plans to use GPT-4 to protect the Icelandic language.

There are still problems with the new language model, however. GPT-4 still struggles to get completely correct answers, which is really a big problem. GPT-4 also sometimes “hallucinates（产生幻觉）”, meaning that it will insist that wrong information is true.

Smartphones are getting boring. The new models either have higher speed or have nicer cameras, but they are not quite different from the ones already in our pockets. This is why scientists are hoping for something new that will change our lives as greatly as smartphones do. The next invention might be smart glasses.

Instead of picking up your smartphone and looking at the screen, all the information you need appears just in front of you, in your glasses. Satellite navigation (卫星导航) directions could appear right on the road. Your smart glasses could guide you to the right shelf in the supermarket!

Smart glasses could also be used in industry. They could show engineers with glasses the instructions about fixing things more quickly. A doctor with glasses could do a difficult operation, guided by someone on the other side of the world. Most technologies are already on the way. For example, one technology called AR, can make digital 3D objects appear as if they are part of the real world. This technology has been widely used in our daily life.

Why can’t we all wear smart glasses yet? So far, no one has invented a good way to send images (映像) of our world onto glasses. However, with the fast development of technology, smart glasses could arrive much sooner than we think.
