GPT-3 (short for "Generative Pre-trained Transformer 3") is a speech-processing artificial intelligence (AI) developed by OpenAI. With a capacity of 175 billion parameters, it is one of the largest and most powerful AI models for language processing to date.

GPT-3 can generate human-like text and perform a wide range of language-based tasks, such as translation, summarisation and content generation. It is trained on a huge dataset of internet content and has the ability to learn and adapt to new tasks and language styles.

GPT-3 is used in a variety of applications, including chatbots, content creation and natural language processing. Its ability to generate human-like text has made it a popular choice for creating chatbots, which are AI-powered programmes that can hold conversations with users via text or speech.

Overall, GPT-3 is a powerful and versatile AI tool that is being used in a variety of applications to improve speech processing and enable the creation of more sophisticated chatbots and other speech-based technologies.
