GPT (ChatGPT): GPT is a generative model based on a transformer architecture. It uses a unidirectional approach, processing input sequences from left to right.
BERT: BERT is a pre-training technique for natural language processing tasks. It utilizes a bidirectional transformer, considering context from both the left and right of a given word.
2. Training Objective:
GPT (ChatGPT): Trained to predict the next word in a sentence, promoting language understanding and coherence.
BERT: Trained to predict missing words in a sentence using bidirectional context, focusing on understanding the relationship between words.
3. Context Understanding:
GPT (ChatGPT): Understands context by processing words sequentially, relying on context from previous words in the sequence.
BERT: Captures contextual information bidirectionally, considering both preceding and succeeding words in a sentence.
4. Task Specificity:
GPT (ChatGPT): General-purpose language model capable of a wide range of language tasks but may require task-specific fine-tuning.
BERT: Initially designed for pre-training and later fine-tuned for specific NLP tasks like question answering and sentiment analysis.
5. Context Window:
GPT (ChatGPT): Context window extends from the beginning of the sequence to the current word, allowing it to generate coherent and contextually relevant responses.
BERT: Context window extends in both directions from the target word, capturing a broader context for each word.
6. Use Cases:
GPT (ChatGPT): Well-suited for natural language understanding, text completion, and conversational AI applications.
BERT: Effective for tasks that benefit from understanding the context of a word within a sentence, such as question answering and named entity recognition.
7. Training Data:
GPT (ChatGPT): Pre-trained on a diverse dataset containing parts of the Internet, which helps it generate contextually relevant responses.
BERT: Pre-trained on a large corpus of text, often from Wikipedia, to capture general language understanding.
8. Fine-Tuning:
GPT (ChatGPT): Can be fine-tuned on specific tasks, but the fine-tuning process may require a substantial amount of task-specific data.
BERT: Fine-tuned for specific downstream tasks, improving performance on tasks like sentiment analysis or named entity recognition.
9. Token Masking:
GPT (ChatGPT): No token masking during pre-training; it predicts the next word in a sequence without hiding any words.
BERT: Employs token masking during pre-training, where some words are randomly replaced with "[MASK]" to learn bidirectional context.
10. Model Size and Parameters:
GPT (ChatGPT): Comes in different versions with varying numbers of parameters (e.g., GPT-3 has 175 billion parameters).
BERT: The original BERT models have fewer parameters compared to some of the larger GPT models.
