How I Made AI Behave Differently Based on Conversation Context (Multi-Role Prompt Engineering)

Short summary

Multi-role AI requires behavioral constraints rather than personality descriptions — explicit rules and motivations produce more consistent behavior than adjectives alone. Inject simplified conversation state (speaker, previous statements, mood) before each AI call to maintain context without token waste. Adjust model temperature strategically: lower (0.3-0.5) for consistent, authoritative characters; higher (0.7-0.9) for emotional or unpredictable ones.

  • Use behavioral rules and constraints instead of adjectives for distinct character responses
  • Inject simplified conversation state before each AI call to maintain contextual awareness
  • Adjust temperature: 0.3-0.5 for consistent characters, 0.7-0.9 for emotional unpredictability

Generated with AI, which can make mistakes.
