Best Practices for Using HermesAI

  • Refine Your Scenarios and Roles: Create specialized scenarios and roles tailored to specific workflows or learning goals. For example, build a "Programming Assistant" scenario with roles like "Python Expert" and "Frontend Engineer" for a focused development environment.
  • Write Effective Prompts: Craft clear, specific prompts for each AI role to significantly improve response quality and consistency. Include role positioning, task objectives, and output format requirements in your prompts for best results.
  • Flexibly Adjust API Parameters:
    • Increase Temperature and Top P when you need more creative or divergent thinking from the AI.
    • Decrease Temperature and Top P for more stable, focused, and precise responses.
    • Control response length with Max Tokens to avoid overly long or short answers.
    • Enable Think mode to allow the AI to reason internally before responding — especially useful for complex questions in multi-role conversations.
  • Use @Mentions Effectively: In multi-role scenarios, use @RoleName to direct questions to specific AI roles and maintain organized, focused conversations.
  • Back Up Your Data Regularly: Use the built-in "Export" feature to regularly back up your API configurations, chat scenarios, role definitions, and conversation history to prevent data loss.
