ChatGPT machine learning-based tech

 ChatGPT is a large language model, trained on a massive amount of text and voice data. It is based on the machine learning technique known as Reinforcement Learning from Human Feedback (RLHF). RLHF is effective in generating human-like text responses to a given prompt.

Initial development involved human AI trainers providing the model with conversations in which they played both sides — the user and an AI assistant.

The technology has real-world applications such as digital marketing, online content creation, answering customer service queries, or even aiding in debugging code.

Despite the recent glitches in the US economy, last year Venture capital investment in AI development and companies rose to nearly $13 billion. And by October 2023, $6 billion in investment money continues to drive AI.
