Scale AITextPrompt Response Writing SFT

I crafted prompts with predefined categories and subcategories, following a three-level complexity scale: easy, medium, and high constraints. Subsequently, I evaluated the AI-generated responses, identified the most effective one, and made modifications as necessary.
