MiniMax H3 tested: best open-source motion and prompt adherence, but physics and audio lag
SensitiveUse7864 · reddit · 2026-08-20
After a week of testing, a Reddit user argues MiniMax H3 is king among open-source video models for motion and prompt adherence, with physics and fight scenes as its main weakness. The community hype about its 'best' audio quality is overstated: H3 is better than other open-source models, but audio still isn't great. The author asks whether dialogue and sound are baked into the base model or the audio VAE — if the latter, the VAE could be swapped to upgrade audio; if the former, a full fine-tune would be needed.
