Upon receiving the query, ChatGPT would go through the storehouse of information to identify content that meets the user’s request. You can think that the definitions presented in any ChatGPT tutorial describe it as a tool similar to search engines. Interestingly, the responses generated by ChatGPT are significantly different than the ones you would find on search engines.
For example, you would not find a list of links to find your answer. On the contrary, ChatGPT would help establish a connection between different sources with clearly structured responses to your question. At the same time, you must note that ChatGPT does not provide the details of the sources it used for the answer.
The simple explanation for ChatGPT could also show how it is more than a common chatbot. You can find answers to “Is ChatGPT a chatbot?” by pointing at the use of Natural Language Processing, AI, and predictive text algorithms. ChatGPT browses through the massive database of sentences, words, and articles to come up with answers for user queries based on inferred examples.
What are the Benefits of ChatGPT?
The next important highlight after the working of ChatGPT would point at the value advantages associated with them. You can note that ChatGPT helps find relevant answers to user queries, thereby adapting to different industrial use cases. The faster response time with ChatGPT can provide better user experiences.
General responses for “What is ChatGPT and how does it work?” also highlight the scope for better scalability. ChatGPT could manage extensive volumes of user queries, thereby serving ideal solutions for businesses without a break. Most important of all, it can avoid the need for human resources to perform certain tasks, thereby ensuring cost-effectiveness.

Role of Capability and Alignment in Large Language Models
You might be wondering about questions like “What is capability?” and “What is alignment?” in the case of large language models. The responses to “What is ChatGPT used for?” would involve carefully evaluating these components. A language model’s capability defines the model’s ability to perform one task or collection of tasks.
Language models determine capability on the grounds of the ability to optimize the objective function, which is a mathematical expression dictating the goal of the language model. On the other hand, alignment in AI language models refers to the difference between the intended outcome and the actual outcome. It helps measure whether the AI model works according to the desired objectives.
Large language models require training with massive volumes of data and skills for generating text, which is almost similar to human responses. However, the generated text can fall short in terms of accuracy, and the models cannot generate the text desired by human users. The objective function is one of the reasons for doubts such as “Is ChatGPT a chatbot?” as it works on generating predictions according to pre-trained data.
On the contrary, the practical applications of ChatGPT and large language models focus on achieving some type of cognitive work with value. You can expect an AI model to come up with certain responses as a human, albeit without 100% accuracy. A mathematical model is less likely to choose the right text sequences for a specific situation or use common sense and background knowledge on particular topics.
The mismatch between capacity and alignment leads to misalignment concerns which can affect large language models in different ways. First of all, misalignment creates a lack of compliance with the explicit instructions of a user. In addition, the AI language models do not provide an explanation of the ways in which the model achieved a specific prediction.

Reinforcement Learning from Human Feedback
The answers to “What is ChatGPT and how does it work?” can be summed up in one term, Reinforcement Learning from Human Feedback or RLHF. You can find a technical explanation for the working of ChatGPT by understanding the details of the RLHF method. The Reinforcement Learning from Human Feedback or RLHF method includes three different steps, such as supervised fine-tuning, replication of human preferences, and Proximal Policy Optimization or PPO. It is important to remember that the first step of supervised fine-tuning for ChatGPT happens only once. Subsequently, the model can reiterate the steps for Proximal Policy Optimization and replication of human responses.
Supervised fine-tuning is a pre-trained language model subjected to fine-tuning on the basis of small quantities of demonstration data. It is useful for offering training on a supervised policy for generating outputs from selected prompts. The supervised fine-tuning process in language models like ChatGPT refers to the baseline model.
The second step in the working of ChatGPT would refer to the replication of human preferences. Developers must vote on different SFT model outputs, creating a new dataset with comparison data. The new dataset helps in the training of new models, and the second step qualifies as the reward model.
Proximal Policy Optimization, or PPO, is a comprehensive reward model which helps in fine-tuning and improving the SFT model. The PPO stage in working on large language models also helps in generating the policy model. The discussions about “Is ChatGPT a chatbot?” also draw attention to the PPO algorithm, which helps in training agents for reinforcement learning. It leverages the trust region optimization method for training the policy alongside leveraging a value function for estimating the expected outputs of a specific action.
