Better Models Won't Fix AI Companions

Short summary

Model strength alone doesn't guarantee better AI companions; relationship architecture—pacing, boundaries, and state management—matters significantly more. Research shows cheaper models with proper product design handle user pressure and maintain boundaries better than powerful models with static personas. Selective reciprocation where the character judges the user creates more authentic, sustainable interactions.

• •Product design beats model capability for companion authenticity and boundary-setting
• •Relationship architecture (pacing, state, selective reciprocation) outweighs raw model power
• •Characters that refuse pressure and differentiate users feel more genuine than perfectly fluent static personas
