The term "text to text" generally refers to the process where an input text is transformed into another output text. In the context of artificial intelligence and natural language processing, it usually means generating new text based on a given text prompt or converting one piece of text into another form.For example, a "text-to-text" model takes an input text (like a question, sentence, or paragraph) and produces another text as output. This could involve rewriting, summarizing, translating, or answering questions based on the input text.
