Complete guide to ChatGPT | How to use ChatGPT for free?
What is ChatGPT?
ChatGPT is a pre-trained language model developed by OpenAI. It is a transformer-based neural network that uses unsupervised learning to generate human-like text. The model is trained on a massive dataset of conversational text, making it capable of understanding and responding to a wide range of topics and questions.
The name ChatGPT is an acronym for “Conversational Generative Pre-training Transformer” which emphasizes the model’s ability to understand and generate text that is appropriate for conversation. It was trained on the internet’s largest conversational dataset, the “Conversational Pre-training Corpus” (CPC), which contains over 570GB of text data, including a diverse set of conversations, dialogue, and question-answer pairs. As a result, ChatGPT can respond to prompts in a conversational, contextually-aware and human-like manner.
The model architecture of ChatGPT is based on the transformer architecture. The architecture was introduced in the paper “Attention Is All You Need” by Vaswani et al. (2017). The transformer architecture is a type of neural network that uses self-attention mechanisms to process input data. This allows the model to weigh different parts of the input data differently, depending on their relevance to the task at hand.
ChatGPT uses a transformer-based architecture with 175 billion parameters, that makes it one of the largest language models available. This large number of parameters allows the model to understand and generate text with high accuracy, although it requires a powerful machine to run and fine-tune the model.
One of the key features of ChatGPT is its ability to generate text that is coherent, contextually appropriate, and grammatically correct. This makes it suitable for a variety of natural language processing (NLP) tasks such as text generation, question answering, and conversation simulation. Also, the model can be fine-tuned for specific tasks or domains, allowing it to understand and generate text that is specific to a particular industry, such as legal, medical, or technical language.

Where ChatGPT is still lacking? Weaknesses of ChatGPT
- Lack of understanding and reasoning ability: ChatGPT, like most language models, is not able to understand and reason about the world in the same way that humans can. It has difficulty with tasks that require common sense knowledge or understanding of context.
- Lack of originality: ChatGPT is not able to generate completely original responses, but instead generates responses based on patterns it has seen in the training data. This can make it less flexible and less able to handle novel situations.
- Bias: ChatGPT can be biased towards the training data, which can lead to biased or unfair responses.
- Lack of focus: ChatGPT can sometimes generate overly verbose or irrelevant responses, as it does not have a built-in mechanism to focus on the most important information.
- Lack of self-awareness: ChatGPT does not have self-awareness and does not know when it does not understand or does not know about something.
How to use ChatGPT for free?
There are a few ways to use ChatGPT for free on your browser, although the model might not be as powerful as the one that OpenAI provides:
- OpenAI Playground: OpenAI has a free web-based tool called the OpenAI Playground, which allows you to input text and generate responses using a smaller version of ChatGPT.
The OpenAI Playground is a free web-based tool that allows you to input text and generate responses using a smaller version of ChatGPT. Here are the steps to use it:
