What Is ChatGPT?
What is ChatGPT? The full name of ChatGPT is Chat Generative Pre-trained Transformer. It is a chatbot that was initially released by OpenAI on November 30, 2022. This tool is built on top of OpenAI’s GPT-3 family of large language models. It is well-trained to use both supervised learning and reinforcement learning techniques. The training data includes man pages and information about Internet phenomena and programming languages, including bulletin board systems and the Python programming language.
After the release of ChatGPT, it quickly attracted the attention of many people. In just two months, ChatGPT users reached 100 million. This fully shows that this software caters to the needs of the public and satisfies people’s curiosity.
Main Features in ChatGPT
Usually, the core function of a chatbot is to mimic a human conversationalist. But ChatGPT is more powerful than imagined. You can use ChatGPT to:
- Write and debug computer programs.
- Compose music, teleplays, and fairy tales.
- Write student essays.
- Answer the test questions.
- Write poetry and song lyrics.
- Emulate a Linux system.
- Simulate an entire chat room.
- Play games.
- And more….
It is reported that sometimes Chat GPT’s level of answering questions and writing code is higher than that of humans.
ChatGPT is very clever. It can remember the previous prompts that are given to it in the same conversation. But this may bring offensive outputs. To reduce negative impact, queries are filtered through OpenAI’s company-wide moderation API and potentially racist or sexist prompts are dismissed by technologies.
Limitations in ChatGPT
ChatGPT is not full of advantages, there are limitations in it.
For example, OpenAI has acknowledged that ChatGPT “sometimes writes plausible-sounding but incorrect or nonsensical answers”. You may encounter this situation when you use ChatGPT in large language models. This behavior is called artificial intelligence hallucination.
The reward model of ChatGPT is designed around human oversight. Due to this, the reward model can be over-optimized and thus hinder performance. This is known as Goodhart’s law.
In addition, ChatGPT knows less about the events that occurred after 2021. This may indicate that the update of Chat GPT in some aspects is not very timely.
Is ChatGPT Free?
ChatGPT was launched as initially free to the public, but the company plans to monetize the service later. This situation is normal.
Now, you can download the installer of ChatGPT for Windows, Mac, and Linux from github.com. Then, you can install it on your device with the help of the installer you have downloaded.
You can also download and install the ChatGPT app on Android, iPhone, or iPad for further use.
If you don’t want to use the ChatGPT app, you can choose to use the online ChatGPT service. It is also free.
Wrap Things up
As a new chatbot, ChatGPT is successful. It has attracted millions of users in a short period of time. But like any other software, ChatGPT also has many disadvantages and limitations. This service is still a work in process. You should believe that it will get better and better in the future.
