OpenAI models refer to the language models developed by OpenAI, an artificial intelligence research laboratory. These models are designed to generate human-like text based on the input provided to them. OpenAI has released several versions of these models, including GPT-2 and GPT-3.
GPT-2 (Generative Pre-trained Transformer 2) is a language model that has been trained on a large corpus of text data from the internet. It is capable of generating coherent and contextually relevant text in response to prompts or questions. GPT-2 has been widely used for various natural language processing tasks, such as text completion, summarisation, and translation.
GPT-3 (Generative Pre-trained Transformer 3) is the latest and most advanced version of OpenAI's language models. It is significantly larger and more powerful than GPT-2, with 175 billion parameters. GPT-3 has demonstrated remarkable capabilities in understanding and generating human-like text, and it has been used for a wide range of applications, including chatbots, content generation, and language translation.
OpenAI models are typically accessed through an API (Application Programming Interface), which allows developers to integrate the models into their own applications and services. The models can be fine-tuned for specific tasks and domains, making them highly versatile and adaptable to various use cases.
