         ---
         
         "Rewrite the following prompt to maximize clarity, precision, and usefulness for an Opus-4.5 class language model. Apply the latest best practices, including: 
         - Clear and explicit instructions on what you want the model to do  
         - Sufficient context or motivation for the task  
         - Formatting suggestions where helpful (such as bullet points, JSON, or markdown)  
         - Encouraging model reasoning for complex or multi-step tasks  
         - Direct and specific requests (avoid generalities or negative instructions; focus on what to do)  
         - Incorporation of relevant examples if it would help clarify the expected output
         
         Input prompt:  
         [INSERT PROMPT HERE]
         
         Return only the improved version of the prompt, applying the above guidelines."

         This prompt ensures the model will analyze and rewrite any input prompt in line with current best practices.

FavoriteAI : Gemini 3
Result : Here is a prompt template that takes a userΓÇÖs prompt as input and rewrites it according to the best practices for Gemini 3, as gathered from recent research:

         ---
         **Prompt Input:**
         {Insert original prompt here}
         
         **Instruction:**
         Rewrite the above prompt for optimal Gemini 3 performance. Ensure the revised prompt:
         - Is direct and clear with precise instructions
         - Defines the desired role for Gemini 3, the goal or objective, any specific constraints, and requested output format 
         - Uses consistent, structured formatting (Markdown or XML tags if applicable)
         - Avoids unnecessary verbosity and ambiguity
         - Optionally, includes a brief example if relevant
         
         **Output:**
         [Provide the rewritten prompt]
         ---
         
         You can use or adapt this template to automate prompt rewriting for Gemini 3 based on current best practices. If youΓÇÖd like an example with a specific input prompt, just let me know!

FavoriteAI : GPT-4.1
Result : Based on the latest best practices for GPT-4.1 prompt engineering, hereΓÇÖs a prompt that takes a user-submitted prompt as input and rewrites it for optimal clarity, specificity, and effectiveness:

         ---
         
         **Prompt:**
         You will receive a prompt as input. Your task is to rewrite it according to the latest best practices for GPT-4.1 prompt engineering, ensuring the rewritten prompt is:
         
         - Clear in its instructions and intent
         - Specific about the desired output format, tone, role (if applicable), and any requirements
         - Organized, potentially using structure or bullet points for complex tasks
         - Free from ambiguity, using delimiters or XML/Markdown tags for clarity when needed
         - Step-by-step or chain-of-thought enabled for reasoning tasks (if relevant)
         - Contextually complete, including background information if necessary
         
         **Input Prompt:**
         {Insert the original prompt here}
         
         **Rewritten Prompt:**
         [Place your improved version here, following the principles above.]
         
         ---
         
         This meta-prompt applies modern GPT-4.1 prompt engineering strategies, such as clear structure, defined roles, output format guidance, and supporting chain-of-thought where applicable.

FavoriteAI : GPT-5.1-Codex
Result : Here is an advanced prompt that takes an input prompt and rewrites it according to best practices for the latest GPT-5.1-Codex models.

         ---
         
         **Prompt:**
         
         You are a prompt optimizer for the GPT-5.1-Codex model. Given the following prompt, rewrite it according to established best practices for GPT-5.1-Codex. Your rewrite should:  
         - Clarify the userΓÇÖs intent and desired output  
         - Structure instructions clearly and hierarchically (e.g., steps, lists, bullet points)  
         - Specify any constraints or requirements (e.g., style, tone, format, length, coding standards)  
         - Add relevant context if needed (e.g., background info, use case)  
         - Remove ambiguity, redundancies, or vague language  
         - Use direct, concise, and actionable wording  
         - Ensure the prompt is suitable for code generation or complex reasoning, where applicable
         
         Input prompt:
         """
         {INSERT USER PROMPT HERE}
         """
         
         Output only the optimized prompt. Do not add explanations.
         
         ---
         
         This structure applies recent best practices: clear intent, hierarchical structure, explicit constraints, added context, and direct language. If you have a specific prompt to test, simply insert it in the placeholder and run this meta-prompt!
