How to Choose a Persona

1. Match the Task to the Expert

Choose a persona whose expertise aligns with your task. Using architect for code generation will give better results than a general-purpose model.

2. Consider Quality vs. Speed

Use Fast variants for prototyping and iteration. Switch to Standard for production work. Use Pro for institutional-grade outputs with advanced frameworks. Use Ultra for mission-critical work requiring arbiter review and zero-tolerance for errors.

3. Test and Iterate

Try different personas to find the best fit for your specific use case. Each persona has a distinct voice and approach that may resonate differently with your needs.

NEW: Ultra Tier Personas

We've added a new Ultra tier for mission-critical work. Ultra personas include an additional Arbiter role that performs final approval before delivery, ensuring zero-tolerance for errors. Currently available: Counsel_Ultra, Guardian_Ultra, Forecaster_Ultra, and Strategist_Ultra.

System Prompts & Advanced Frameworks

All personas now include detailed system prompts that define exactly how each role (Composer, Author, Critic, Editor, Arbiter) approaches their work. Pro personas leverage advanced frameworks like AIDA, PAS, BAB for copywriting, Hero's Journey for storytelling, and North Star Metric for growth strategies.
