SSj_Enforcer · reddit · 2026-10-05
A Reddit user documents how to stop H3 from generating unprompted gibberish speech at the start of dialogue-free shots. Key finding: the model needs an action to hold silence, even a barely visible one. Verified phrasings include "stands still thinking to himself," "breathes softly," "is mute while he stands still," and "examines/stares intently at" the other subject. Full structured prompt template with subject definitions and retention analysis included.
