MiniMax H3 Shows Significant Drop in Prompt Adherence at Higher Resolutions
Bobun · reddit · 2026-08-08
A developer running MiniMax H3 on 4×B300 reports that the model's prompt adherence varies drastically depending on the generation resolution.
- Low-Resolution Performs Well: At 352p/416p, the model correctly follows shot structure, camera angles, and character placement.
- High-Resolution Degrades: At 768p, prompt adherence drops dramatically, ignoring camera angles and altering character placement.
- More Steps Don't Help: Increasing inference steps slightly improves visual coherence but fails to fix structural guidance or composition.
The author suspects this relates to changing latent dimensions and asks the community if resolution-specific settings like RoPE or positional encoding need adjustment.
