前两天收到OpenAI开通ChatGPT API 4的消息，终于可以玩玩了。
于是将公众号的后台也升级到ChatGPT API 4了。
由于ChatGPT API 4的价格是3.5版本的20倍左右，所以将免费提问的额度进行了调整。为了方便体验，每个公众号粉丝已分发至少3次提问机会。
另外，公众号目前仅做学习及测试使用，不提供付费服务。
感觉ChatGPT API 4和3.5最大区别还是在面对复杂问题时，答案的精准程度。两者目前都有共同的缺点: 最新的数据用的还是2021年9月之前的，并且没有联网的功能。除了文本，还不支持其它格式的输入输出。
不管怎样，质量有所提高的回答，已经不错啦。
关于免费提问的福利，以后有新的消息，再另行告知。
附上OpenAI官方给的ChatGPT API 4 的介绍:
https://platform.openai.com/docs/models/gpt-4
GPT-4 is a large multimodal model (accepting text inputs and emitting text outputs today, with image inputs coming in the future) that can solve difficult problems with greater accuracy than any of our previous models, thanks to its broader general knowledge and advanced reasoning capabilities. Like gpt-3.5-turbo, GPT-4 is optimized for chat but works well for traditional completions tasks both using the Chat Completions API.
For many basic tasks, the difference between GPT-4 and GPT-3.5 models is not significant. However, in more complex reasoning situations, GPT-4 is much more capable than any of our previous models.
