[账号注册] Differences between free and paid ChatGPT, and the benefits of PLUS membership

As of December 20, 2023, the free version is 3.5 and earlier versions. Its knowledge base is relatively old, around September or October 2021. It only has text generation capabilities. The paid version is version 4.0, a Plus membership, which allows the use of more feature plugins, such as the most popular DALLE3, which can generate images from text. Its knowledge base is also updated in real time. The cost is $20 per month, about RMB 140.


[baike]Specific Feature Limitations[/baike]
1. Token/character limits: the free version has limits on input and output characters and the number of uses.
2. The free version’s knowledge base updates slowly and is older than that of paid members.
3. The free version cannot upload files or images, which means it cannot perform analysis work.
4. The free version cannot draw or use dalle3.
5. The free version does not support custom gpts.
6. The free version does not support plugins.


[baike]How to Choose[/baike]If you only need text generation, such as articles, novels, PPTs, scripts, and other content, the free version is enough.



[baike]ChatGPT API Introduction[/baike]ChatGPT supports external API calls, but the API is billed by usage count and token usage. If you want to build wrapper tools, do data analysis, or make a large number of calls, you need to activate and top up the API.
