ChatGPT has been making big waves, and it has come a long way in a very short time.
GPT-1
ChatGPT is a large language model developed by OpenAI that is capable of generating human-like responses to natural language input. It is based on the Generative Pre-trained Transformer (GPT) architecture, which was first introduced in 2018 with the release of GPT-1.
GPT-1 was a significant breakthrough in the field of natural language processing, as it demonstrated that large language models could be trained on massive amounts of text data and produce coherent, human-like responses. However, it had limitations in terms of its size and scope, and was unable to generate responses that were as complex or nuanced as those produced by humans.
GPT-2
In response to these limitations, OpenAI developed GPT-2, which was released in 2019. GPT-2 was much larger than its predecessor, with 1.5 billion parameters compared to GPT-1’s 117 million parameters. This allowed it to generate much more complex responses, and it was even capable of generating coherent paragraphs of text on its own.
However, GPT-2 was not released to the public due to concerns about its potential misuse. Instead, OpenAI released a smaller version of the model called GPT-2-117M, which had the same number of parameters as GPT-1 but was trained on a much larger dataset.
GPT-3
In 2020, OpenAI released GPT-3, which was the largest and most powerful language model yet. It had 175 billion parameters, and was capable of generating responses that were often indistinguishable from those produced by humans. It was able to perform a wide range of natural language tasks, such as translation, summarization, and question-answering, and it quickly became one of the most talked-about AI models of all time.
GPT-3.5: The Modern Era
In early 2022, OpenAI released an update to GPT-3 called GPT-3.5. This update included improvements to the model’s performance and efficiency, as well as the addition of new features such as multi-task learning and conversational AI capabilities.
And now, as of March 2023, GPT-4 has been released with all new capabilities. The times they are a’ changin’.
