ChatGPT is a language model that can be used to generate human-like responses to user inputs. The model is based on the GPT-3 architecture and has been trained on a massive amount of text data. The chatbot is capable of understanding natural language and providing appropriate responses to user queries.

  • In this article, we will discuss how to create a ChatGPT clone with context. We will walk through the steps involved in training the model and creating a basic chatbot that can understand and respond to user inputs.


    Before we start, there are a few prerequisites that need to be in place:

    Python 3.6 or higher
    CUDA (Optional, for GPU acceleration)
    Step 1: Collecting Data

    The first step in creating a ChatGPT clone is to collect data. The model needs to be trained on a large corpus of text data to learn how to generate responses. You can use any publicly available dataset or collect your own data.

    There are many websites that provide datasets for natural language processing (NLP) tasks. Some popular datasets are:

    Cornell Movie Dialogs Corpus
    Ubuntu Dialogue Corpus
    Open Subtitles Corpus
    Twitter Dataset
    Once you have collected the data, you need to preprocess it to remove any unnecessary information such as HTML tags, special characters, and punctuation.

    Step 2: Training the Model

    The next step is to train the model. We will be using the GPT-2 architecture for this purpose. The GPT-2 architecture has been pre-trained on a massive amount of text data and can be fine-tuned for specific tasks.

    To train the model, we will be using the Transformers library, which provides pre-built models and tools for training language models. The library is built on top of PyTorch, a popular deep learning framework.

    The following code snippet shows how to load the GPT-2 model from the Transformers library and fine-tune it for a specific task:

    Copy code
    from transformers import GPT2Tokenizer, GPT2LMHeadModel

    tokenizer = GPT2Tokenizer.from_pretrained('gpt2')
    model = GPT2LMHeadModel.from_pretrained('gpt2')

    In the code above, we first load the GPT-2 tokenizer and model from the Transformers library. We then set the model to training mode by calling the train() function.

    To fine-tune the model for a specific task, we need to provide it with our own dataset. We can do this by creating a DataLoader object that reads the dataset and passes it to the model during training.

    The following code snippet shows how to create a DataLoader object and train the model on a dataset:

    Copy code
    from import Dataset, DataLoader

    class MyDataset(Dataset):
    def __init__(self, data): = data

    def __getitem__(self, index):

    def __len__(self):
    return len(

    data = [...] # Your data here

    dataset = MyDataset(data)
    dataloader = DataLoader(dataset, batch_size=16, shuffle=True)

    for batch in dataloader:
    input_ids = tokenizer.encode(batch, return_tensors='pt')
    output = model(input_ids, labels=input_ids)
    loss = output.loss
    In the code above, we first define a custom dataset that reads our data and returns it when indexed. We then create a DataLoader object that reads batches of data from the dataset.

    During training, we encode the input data using the GPT-2 tokenizer and pass it to the model.
