Merlin : Best AI Chatbot Powered By GPT-4 - Perfect Guide For AI Beginner

Since the appearance of the GPT-4 from OpenAI, we can feel closer to the life with AI. I am also one of them who got attracted by the hidden potential for GPT-4.

I really wanted to use ChatGPT in Vietnam. But unfortunately, ChatGPT is not available in Vietnam at the moment. (To be honest, there is a way to use ChatGPT in Vietnam, but it’s a bit complex and hassle.)

When I was looking for a service like ChatGPT that could be used in Vietnam, I found Merlin. I hope to show how to use Merlin and its attractions on this post.

In Order To Use Chatbot With GPT Safely #

Althought the chatbot services powered by GPT seems perfect, but I guess there are a few things we need to be careful. In order to avoid any troubles related to GPT services, let’s keep these in minds.

1. Don’t Believe 100% For ChatGPT Answers #

It’s undeniably true that GPT services can probably change the world. But they don’t always return 100% correct answers.

So, it’s important to examine their answer and use it wisely.

2. Don’t Input Credential Information On ChatGPT #

Not only merlin, chatbot services backed up by ChatGPT are powered by deep-learning. They learn by our input everytime.

If you input some important information (e.g. credentials or API keys,password etc) , AI will learn and might return the answer with credentials to somebody else.

So please avoid inputting any credential-like information, it will result in the security violation in the worst case.
