GPT vs. BERT: What’s the Difference and Which One is Better?
The rise of natural language processing has been astounding and ChatGPT is a prime example of its capabilities. Thanks to transformer architecture models such as GPT-3, GPT-4, and BERT, AI can now engage in human-like conversations and even write code. But which language model is better and what sets them apart? Let’s dive in and find out.
Explaining GPT-3 and GPT-4
Generative Pre-trained Transformer 3 or GPT-3 is an autoregressive language model created by OpenAI in June 2020. It is one of the largest language models ever constructed with a transformer architecture consisting of 175 billion parameters. With the ability to generate natural language text, answer questions, compose poetry, and write complete articles, it has the potential to revolutionize chatbots, language translation, and content creation.
GPT-4 is the latest and largest in a series of GPT models and is accessible with a ChatGPT Plus subscription. With an estimated one trillion parameters, it is six times larger than the GPT-3 model and therefore, much more accurate.
What is BERT?
Bidirectional Encoder Representations from Transformers or BERT is a pre-training language representation model created by Google in 2018. Unlike other NLP models, BERT uses bidirectional flow during processing, allowing it to use context from both directions. This allows BERT to better understand the meaning of words in context and provide more accurate search results for complex queries.
The Main Differences Between GPT and BERT
Architecture:
BERT uses bidirectional context representation, processing text from both left-to-right and right-to-left to capture context from both ends. GPT, on the other hand, generates text sequentially from left to right, predicting the next word in a sentence based on the preceding words.
Training Data:
BERT is trained on a masked language model, predicting the next word based on contextual information. However, GPT-3 is trained on a large-scale corpus of text containing web pages, articles, books, and Common Crawl’s publicly available archive of web content.
Use Cases:
BERT is more capable for sentiment analysis, named entity recognition, and answering questions accurately. GPT excels in content creation, text summarization, and machine translation.
Usability:
While ChatGPT offers easy access to the GPT model, using BERT requires downloading the Jupyter Notebook and setting up a development environment using Google Colab or TensorFlow.
BERT and GPT Show the Capabilities of AI
The introduction of BERT and GPT has disrupted workflows and changed job functions. Though there is skepticism around AI adoption and its impact on jobs, many companies, including Google and OpenAI, are working to establish controls and regulate AI technology for the betterment of the future.
In conclusion, both BERT and GPT have unique features that serve different purposes. Depending on your use case, one language model may be better than the other. However, the capabilities of AI shown through the development of these models are truly remarkable.
Editor Notes
The technological advancements in language processing mean that we can now converse with AI in a more human-like manner. The applications that have been developed from GPT and BERT training models are a clear indication of the direction that the AI industry is heading. However, it is crucial that companies and organizations establish controls and regulations to ensure that these advancements are beneficial for society as a whole.
