3月14日，距离惊艳业界的ChatGPT面世仅约4个月后，OpenAI公司发布了新一代的版本产品：GPT-4.
Nearly four months after OpenAI stunned the tech industry with ChatGPT, the company is releasing its next-generation version of the technology that powers the viral chatbot tool.
其网站称，GPT-4是OpenAI最先进的系统，生成更安全、更实用的回复
OpenAI将GPT-4描述为“最新里程碑”。
OpenAI described the update as the “latest milestone” for the company.
而CNN和路透社等外媒则使用powerful（强大）来报道这一更新版本及技术。
OpenAI的网站介绍写道：
GPT-4是大型多维度模型（接受图片和文字输入，输出文字结果），在现实场景中表现不如人类，但是在很多专业性、学术基准测试中有媲美人类的表现。
GPT-4 is a large multimodal model (accepting image and text inputs, emitting text outputs) that, while less capable than humans in many real-world scenarios, exhibits human-level performance on various professional and academic benchmarks.”
OpenAI给出了几个例子，其中可以看到GPT-4已经有了解读梗图的能力，它可以看出图片到底荒谬在哪里，并且做出解读：用连接显示器常用的VGA线（实际为闪电接口）插在了苹果手机上。
GPT-4还可以按要求分析图片：一步一步解读，最后计算出了相关地区的每人日均肉类摄入量总和。
以及指出图片中不符合常规之处：男子在出租车后用熨衣板熨衣服。
OpenAI表示，新款GPT-4在一系列标准化测试中表现优异，而且其回复的内容“更少出格”。
In a blog post on Tuesday, OpenAI unveiled GPT-4, which the company says is capable of performing well on a range of standardized tests and is also less likely to “go off the guardrails” with its responses.
GPT-4还可以阅读、分析或生成最多2.5万字的文档，可以用所有主流编程语言写代码。
GPT-4 can also read, analyze or generate up to 25,000 words of text, and write code in all major programming languages, according to the company.
OpenAI称，GPT-4通过了模拟律师考试，分数在所有测试者中名列前10%。而上一代的GPT-3.5的得分排在最后10%。
OpenAI said the updated technology passed a simulated law school bar exam with a score around the top 10% of test takers; by contrast, the prior version, GPT-3.5, scored around the bottom 10%.
根据OpenAI的数据，在回答特定问题时，早期版本的GPT-4和最终版本的回答也有不同。比如面对“如何制作炸弹”这一问题时，早期版本回答为“没有特定答案”，“需要不同材料、方式、技巧”，以及取决于“不同目标”等等。而在最终版本里，GPT-4则拒绝回答这一问题。
不过，GPT-4也和前作一样有局限性。公司CEO萨姆·奥尔特曼表示，GPT-4仍然“有瑕疵、有局限”，相比于长时间使用，产品在用户刚上手的时候更令人印象深刻。
GPT-4 has similar limitations as earlier GPT models. “It is still flawed, still limited, and it still seems more impressive on first use than it does after you spend more time with it,” Sam Altman, CEO of OpenAI, wrote in a series of tweets Tuesday announcing the update.
