According to new information, Chat GPT Plus has now been deployed in the Vietnamese market so we can buy and register our accounts, without expecting VPN software or using another phone number to register to use. Use GPT Chat like now. So how is Chat GPT Plus different from regular Chat GPT and how to register for Chat GPT Plus?
What is Chat GPT Plus?
Compared to the Chat GPT version, the Chat GPT Plus package upgrades the experience with many features. When using Chat GPT Plus you will never encounter errors or overloads when connecting to the server. Server response time is also much faster than the regular version.
Especially when the manufacturer launches many new features, those who register for Chat GPT Plus will always be given priority to experience it first. Currently users will need to pay 20 USD per month when registering and using Chat GPT Plus.
Advantages of upgrading to ChatGPT Plus
Beyond the obvious upgrades, such as access to the latest version of OpenAI's GPT language model and new features, the real benefits are more subtle. For example, GPT-4 understands context and handles language much better.
1. Higher quality response with GPT-4
GPT-4 is said to have trained on over a trillion parameters, which means it is better than GPT-3.5 at recognizing complex patterns in data to produce better responses. It also has better language processing, contextual understanding, and complex problem-solving skills.

GPT-4 is noticeably better. It gets straight to the point and presents a numbered list illustrating the main discussion points. GPT-4 immediately explains that using simple analogies is the best way to explain the topic to the average person, and that's exactly what it did for each discussion point.

So for most prompts it understands the problem and context better than GPT-3.5. Where you had to try several different prompts to get the desired output from GPT-3.5 (the free version of ChatGPT), GPT-4 produces the same output with significantly fewer prompts.
But these are not all the differences between GPT-4 and GPT-3.5: GPT-4 can receive visual input, it is creative, and its response is also more realistic.
2. Priority access to new features

OpenAI is constantly creating new features to further improve their language models. If you sign up for ChatGPT Plus, you'll get priority access to OpenAI's latest releases, with the opportunity to test them before free users.
3. Faster response time

Slow response times and limited availability are two of the most annoying things about the standard version of ChatGPT. If you upgrade to the Plus version, both issues will be fixed. When using the Plus version, you can choose to use the default model (GPT 3.5), GPT-4, or even the old version available at launch (although this is being phased out).
Although the default model is more or less the same as the old version in terms of response, it is much faster. Another interesting insight is that when asking both GPT-3.5 and GPT-4 to explain quantum mechanics (discussed above), GPT-3.5 is significantly faster.
GPT-4 is slower than GPT-3.5 because it requires more parameters. Because it needs access to more information, it takes longer to respond.
4. Higher availability
When using the standard version of ChatGPT, you may encounter an error message stating “ChatGPT is currently operating at full capacity”. Due to the unprecedented popularity of OpenAI's chatbots, millions of people often try to use the service at any given time.
This lack of availability is not an issue with the Plus version, as your access to the chatbot is prioritized during peak hours. Consistent access to ChatGPT is a blessing when your workflow depends heavily on it.

Your Card Was Declined error. Please Try A Different Card to register for GPT Plus Chat
Many people when registering for Chat GPT Plus or upgrading Chat GPT Plus will encounter an error message as shown below.
This error is encountered not only in Vietnam but also in the UK, Canada, etc. markets. This is because OpenAI is not yet synchronized for other markets except in the US. So when using international payment cards, you will receive a red notice not accepting the card you entered.
The only way to fix this error if you encounter it is to use a payment card in the United States and use the information here to continue completing the payment. OpenAI has received feedback from users and will fix it soon. Or you can email feedback to the Open AI team at support@openai.com to notify the problem you encounter.
Disadvantages of upgrading to ChatGPT Plus
While upgrading to ChatGPT Plus certainly sounds easy, you should be aware of some of the downsides to this service.
1. Limited number of reminders

In fact, GPT-4 can produce more than 25,000 words in one go, while GPT-3.5 is limited to 3,000 words/answer. While longer and higher quality responses are a big upgrade, there's an almost equally big limitation holding back GPT-4 users: You can only send 25 new messages every 3 hours.
This hard limit is extremely restrictive, as you'll quickly see that 25 messages isn't a lot. Initially, this limit was about 100 messages, but OpenAI has reduced the time with GPT-4 scaling. Therefore, you have limited access to the latest GPT language model, even if you have purchased a subscription.
2. Microsoft's Bing Chat is free and sometimes better

There are many differences between ChatGPT and Bing Chat. One is essentially an AI-powered search engine, while the other is more like a “traditional” chatbot. However, this doesn't mean you can't use Bing Chat for similar purposes. It is free to use, can access information from the Internet in real time, does not have many usability problems and also uses GPT-4 technology.
Accessing information directly from the Internet makes Bing Chat much more flexible than ChatGPT. Unfortunately, Microsoft is cautious with how it responds to certain prompts. Sometimes Bing will refuse to respond to controversial topics. However, you should try it out before paying for ChatGPT Plus to see if it suits your needs.
3. The free version is still good in most cases
If the pros outweigh the cons for you, then paying $20/month for a highly flexible chatbot doesn't sound too bad. But while all the benefits mentioned above are certainly appealing, it's hard to ignore the obvious – the free version is good enough for most people.
Now, if faster response times and better availability really matter to you, those are enough reasons to upgrade. However, by incorporating the right reminder creation techniques with ChatGPT, you'll find that the free version is still very useful. This isn't really a downside to the Plus version; it's just that the free version is still really useful.
