The AI model known for generating human-like text responses is called GPT (Generative Pre-trained Transformer). Developed by OpenAI, this model leverages deep learning techniques to understand and generate natural language. By training on diverse datasets, GPT can engage in conversation, answer questions, and produce coherent, contextually relevant text. Its applications range from content creation to customer service, demonstrating the capabilities of AI in automating language-based tasks and enhancing user engagement through more natural interactions.
