Chat GPT is back in the headlines!Open AI, 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 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 a matter of 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. GPT4 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 see greater use as a tool to 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. Users can learn language by talking with AI. Another app, Be My Eyes, will have a digital assistant 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, especially with newer information after September 2021. GPT—4 also sometimes " hallucinates". meaning that it will insist（坚持） that wrong information is true.
