ChatGPT is a major technological advancement, potentially more beneficial than modern search engines.

OpenAI recently released a groundbreaking AI system named ChatGPT capable of providing conversational responses to detailed inquiries. This technology is especially remarkable because it has been trained to comprehend the underlying purpose of the questions asked by humans.

People are stunned by this technology’s capacity to give responses similar to those made by humans, leading them to believe that it could eventually revolutionize how people communicate with computers and how data is accessed.

What Is ChatGPT?

OpenAI has built ChatGPT, a huge language model chatbot based on GPT-3.5. This chatbot is remarkable in its capacity to communicate in conversational dialogue form and deliver answers that can look incredibly human-like. Large language models are used to forecast the next word in a sequence of words. With Reinforcement Learning and Human Feedback (RLHF), an extra level of instruction is utilized, which uses human feedback to enable ChatGPT to understand how to adhere to instructions and create answers that satisfy humans.

Who Created ChatGPT?

OpenAI, a San Francisco-based AI company, developed ChatGPT. OpenAI Inc. is the non-profit parent association of the for-profit OpenAI LP. OpenAI is renowned for its famous DALL·E, a deep-learning model that produces pictures from verbal instructions named prompts. Sam Altman, previously president of Y Combinator, is the CEO.

Microsoft has invested $1 billion in forming the Azure AI Platform, and they have a partnership with the platform.

Large Language Models

ChatGPT is an extensive language model that has been educated with a significant sum of data to guess the following word in a sentence correctly. It has been identified that the more data utilized, the better the language model can perform. According to Stanford University, increasing the amount of data positively affects the LLM’s capacity.

“GPT-3 has an impressive 175 billion parameters and was created using 570 gigabytes of text. Its predecessor GPT-2, was significantly smaller at 1.5 billion parameters. This great increase in size dramatically alters the model’s behavior – GPT-3 can execute tasks that it was not taught to do, like translating sentences from English to French, with practically no training samples. This capacity was barely seen in GPT-2. In addition, GPT-3 surpasses models designed to complete tasks for some tasks, although it does not perform as well in other tasks.”

LLMs can guess what the following word or sentence might be in a series of words or sentences by analyzing them in the same way an autocomplete function works. This capability enables LLMs to compose paragraphs and whole pages of material.

Language models limit their ability to understand a human’s intent fully. However, ChatGPT utilizes Reinforcement Learning with Human Feedback training to improve the state of the art.

How Was ChatGPT Trained?

ChatGPT was trained on an extensive dataset of code and information from the internet, such as Reddit discussions, to enhance its ability to understand dialogue and emulate human-like responses.

Additionally, the model underwent Reinforcement Learning with Human Feedback, a cutting-edge technique that trains the AI to comprehend human expectations when posed with a question. This approach to training the language model is groundbreaking as it goes beyond the traditional method of training the model to predict the next word.

A research paper published in March 2022 titled “Training Language Models to Follow Instructions with Human Feedback” delves into the significance of this revolutionary approach.

“Our objective is to enhance the positive effect of large language models by teaching them to perform following the desired outcomes of a specific group of humans. The conventional method of training language models, which focuses on optimizing the prediction of the next word, needs to be revised to achieve this goal. Our research suggests that our techniques can make language models more useful, accurate, and safe.

It is important to note that simply increasing the size of a language model does not necessarily improve its ability to comprehend the user’s intent. Large language models have been known to produce misleading, harmful, or unhelpful outputs to the user, indicating a lack of alignment with the user’s needs.”

To evaluate the performance of GPT-3 and InstructGPT (a related model to ChatGPT), the engineers behind ChatGPT enlisted the assistance of external evaluators, known as labelers. The labelers assessed the outputs of both systems, and based on their ratings, the research team arrived at the following conclusions.

“The labelers consistently preferred the outputs of InstructGPT over those of GPT-3. Additionally, the InstructGPT models exhibited enhancements in accuracy compared to GPT-3. Although there were slight improvements in toxicity in InstructGPT models compared to GPT-3, there were no discernible differences in terms of bias.”

The research paper supposes that the results for InstructGPT were generally favorable. However, it also highlights that there is still room for further improvement.

“In summary, our findings suggest that fine-tuning large language models using human preferences significantly enhance their performance across various tasks. However, a considerable amount of work still needs to be done to ensure their safety and dependability.”

What distinguishes ChatGPT from a traditional chatbot is its ability to comprehend human intent in a query and furnish accurate, beneficial, and non-harmful responses, thanks to its specialized training. This allows ChatGPT to challenge certain queries and disregard irrelevant parts of a question.

Another research paper related to ChatGPT illustrates the method used to train the AI to anticipate human preferences. The researchers observed that the metrics traditionally used to evaluate the outputs of natural language processing AI often resulted in machines that performed well on the metrics but failed to align with human expectations. The researchers explained the problem as follows:

“Many machine learning applications optimize for simple metrics that are only approximate indicators of the intended outcome. This can result in issues such as YouTube recommendations promoting sensational or misleading content.”

To address this problem, the researchers designed a solution that involved creating an AI that could produce answers tailored to human preferences. To achieve this, they trained the AI using datasets of human comparisons between various responses, thus enabling the machine to improve its ability to predict answers that were deemed satisfactory by humans.

The research paper “Learning to Summarize from Human Feedback” was published in February 2022. The paper highlights that the training process involved summarizing Reddit posts and that the technique was also evaluated for summarizing news articles. The authors of the paper state:

“In this study, we demonstrate that it is possible to significantly enhance the quality of summaries by training a model to cater to human preferences. We gather a substantial and high-quality dataset of human comparisons between summaries, train a model to anticipate the summary preferred by humans, and use that model as a reward function to fine-tune the summarization policy using reinforcement learning.”

What are the Restrictions of ChatGPT?

Restrictions on Toxic Reply – ChatGPT is specifically designed to refrain from providing harmful or toxic responses and thus will avoid answering such questions.

Quality of Responses Relies on Quality of Directions – A critical restriction of ChatGPT is that the quality of its output is contingent on the quality of the input. In other words, providing expertly crafted prompts results in more accurate answers.

The Responses Generated May Not Always be Accurate – Another limitation is that, since it is trained to furnish responses that appear accurate to humans, the answers may mislead humans into believing that the output is correct. Many users have discovered that ChatGPT can produce incorrect responses, including some that could be more robust.

The moderators at the coding Q&A website Stack Overflow may have undergone an unforeseen outcome of the model’s ability to provide accurate responses to humans. The platform was inundated with user-generated responses from ChatGPT that appeared to be correct, but many of them needed to be corrected.

“This is a temporary measure aimed at reducing the influx of answers and other content generated using ChatGPT. The main issue is that while the answers produced by ChatGPT have a high likelihood of being inaccurate, they often appear plausible.

This creates confusion and hinders the ability of our volunteer moderators to keep up with the influx of content. We hope to re-evaluate and re-implement using ChatGPT in the future, but we are banning its use now.”

The experience of Stack Overflow moderators encountering incorrect ChatGPT answers that appear accurate is something that the creators of ChatGPT, OpenAI, are aware of and had previously warned about in their announcement of the new technology.

OpenAI Outlines the Restrictions of ChatGPT

The OpenAI announcement included a cautionary note that reads as follows:

“ChatGPT occasionally generates answers that sound plausible but are incorrect or nonsensical. Resolving this issue is difficult as:

  • During Reinforcement Learning training, there is currently no definitive source of truth;
  • Training the model to be more cautious leads to it declining questions that it can answer correctly; and
  • Supervised training misleads the model, as the perfect answer relies on what the model knows, rather than what the human demonstrator knows.”

Is ChatGPT Free To Use?

ChatGPT is available free of charge during the “research preview” phase. Users are encouraged to test the chatbot and provide feedback on the responses to improve the AI’s ability to answer questions and learn from its errors. The official announcement from OpenAI states that they are eager to receive feedback about any mistakes made by the model.

“Although we have implemented measures to prevent the model from responding to inappropriate requests, there may be instances where it responds to harmful instructions or displays discriminatory behavior. We are utilizing the Moderation API to flag or block certain types of unsafe content. However, it may have some false negatives and positives for the time being. We are keen to collect user feedback to assist with our ongoing efforts to enhance this system.”

Could Language Models Replace Google Search?

Google has already developed an AI chatbot, LaMDA, which performed so close to the human conversation that a Google engineer claimed LaMDA was sentient. Given the ability of these large language models to answer a wide range of questions, it is not unrealistic to envision a future in which companies such as OpenAI, Google, or Microsoft replace traditional search with an AI chatbot.

The prospect of a question-and-answer chatbot replacing Google concerns those in the search marketing industry. It has prompted discussions within online search marketing communities, such as the popular Facebook SEOSignals Lab, where questions have been raised about the potential shift from search engines to chatbots. Some on social media have proclaimed that ChatGPT will be the next Google.

After testing ChatGPT, it is clear that the concern over search being replaced by a chatbot is not without merit. While the technology still has room for improvement, it is easy to imagine a future in which search and chatbots coexist. However, the current version of ChatGPT seems to be a tool that may eventually require purchasing credits.

What Are The Potential Applications of ChatGPT?

ChatGPT can create code, verses, tunes, and even small tales in the style of a particular writer. Its ability to comprehend instructions makes it more than just an information provider and a tool capable of carrying out a job. This makes it helpful for drafting an essay about literally any subject. ChatGPT can also be used to formulate outlines for articles or even full-length books.

It is capable of answering almost any query which can be expressed in written form.

In Conclusion

ChatGPT was planned to become a service people would have to pay for. After it was made accessible to the public, more than one million people signed up to use it in the initial five days.
