ChatGPT has taken the world by storm. But do you know what GPT, which forms the basis of ChatGPT, really stands for and means?
This post unpacks the full form of GPT and how it powers the groundbreaking chatbot.
What is the Full Form of GPT?
GPT stands for Generative Pretrained Transformer.
In Hindi, it’s full form is जनरेटिव पूर्व-प्रशिक्षित ट्रांसफॉर्मर (Janareṭiva pūrva-praśikṣita ṭrānsaphoṛmara).
So GPT refers to a type of neural network architecture used in natural language processing.
GPT models are built using transformers, which are a type of deep learning model architecture. They are considered Generative AI models because they can generate or output new text based on patterns learned from massive datasets.
The “pretrained” in the name means the models are first trained on huge corpora of text data to acquire generalized language knowledge before being fine-tuned for specific tasks.
For example, GPT-3, which powers ChatGPT, was trained on nearly half a trillion words!
Why are GPTs Important?
GPTs represent a breakthrough in NLP and AI capabilities.
GPT models can understand and generate human-like text and are able to handle complex language tasks like translation, text summarization, and question answering.
ChatGPT leverages a GPT model to have nuanced conversations and provide remarkably human responses.
Google’s PaLM, DeepMind’s Chinchilla, and Meta’s OPT are other examples of powerful GPT models pushing AI forward.
Key Differences Between GPT-2 and GPT-3 and GPT-4
There are a few generations of GPTs already with increasing capabilities:
- GPT-2 (launched 2019) has 1.5 billion parameters. It wowed people with its ability to write articles, poems, code and more when prompted with just a few words.
- GPT-3 (2020) has a whopping 175 billion parameters, over 100x larger than GPT-2! This huge model size enabled the human-like abilities of ChatGPT.
- GPT-4: (2023) GPT-4 is 10x more advanced than its predecessor, GPT-3.5.
GPT-4 enhancement enables the model to better understand context and resulting in more accurate and coherent responses.
So in summary, GPTs represent advanced Transformer-based neural networks that are powering a revolution in AI language abilities. ChatGPT is just one remarkable application of this exciting technology that still has much potential to be tapped.
