What is ChatGPT?

ChatGPT is an artificial intelligence-powered conversational chatbot. It is developed by an independent artificial intelligence research body, OpenAI. In 2015, it was co-founded by its current CEO, Sam Altman, and Elon Musk.

For its development, the natural language processing (NLP) of machine learning is used. To explain its way of working, assume an instance when a user provides the queries as input and it automatically responds by providing back the detailed instructions related to the queries in the form of output. It is developed to respond in such a way. Artificial intelligence and machine learning process the queries entered by the user and generate the response just like a conversation.

The developers used artificial intelligence and machine learning algorithms to interact with the users; it follows a user’s instructions in a prompt and provides a detailed response. There are a few simple steps that users follow to get the responses to their queries using ChatGPT. They simply feed in their query in the prompt, and the chatbot replies with a detailed response to the user’s query in no time.

As per the creators, ChatGPT is different from other artificial intelligence (AI) chatbots. Unlike other AI chatbots, ChatGPT was trained using Reinforcement Learning from Human Feedback (RLHF). AI trainers and reward models utilize RLHF to develop ChatGPT into a bot capable of answering follow-up questions, rejecting inappropriate questions, admitting its mistakes, and challenging incorrect premises.

As defined by ChatGPT- “Its AI is trained on a dataset of internet text and is able to generate human-like text in response to prompts. It can be used for a variety of natural language processing tasks such as language translation, text summarization, and question answering.”

How does ChatGPT work?

ChatGPT works by using a large language model (LLM). The LLM is trained on a massive dataset of text and code. It is trained to learn patterns, grammar, facts, and writing styles. When given a prompt, it predicts the most probable sequence of words to generate a coherent and relevant response. In the final and essential step, it completes your thought or provides the response on request based on its training.

4. Saving time on writing and research.
5. Assisting with learning and problem-solving.

Are there any limitations of ChatGPT?

Of course, it has some limitations too. The following are some of its limitations:

1. It lacks the real-time information. Its knowledge cutoff means it doesn’t know about recent events (unless Browse is enabled for Plus users).
2. It can hallucinate as it may generate incorrect, nonsensical, or biased information.
3. It has no true understanding, as it doesn’t “think” or “understand” in the human sense; it’s a pattern-matching system.
4. It has context window limits as it struggles with very long conversations or complex and multi-layered requests.
5. Sometimes it can reflect biases present in its training data.
6. Arising ethical concerns due to misinformation and misuse for malicious purposes.

Can ChatGPT replace Google or Humans?

Google: Not entirely. ChatGPT is great for generating new text and explanations, but Google is superior for finding specific, real-time, verifiable information from diverse sources. Search engines provide links, images, news, and structured data that ChatGPT doesn’t. They complement each other.

Humans: No, it cannot replace humans. ChatGPT is a tool that assists and augments human capabilities, automating tasks and providing information. It lacks human creativity, critical thinking, emotional intelligence, moral reasoning, and the ability to act in the real world. Human oversight and judgment remain essential.
