MiniMax H3 vs. LTX 2.3: Wins Big on Human Liveliness, Loses on Long Videos
Chemical-Bicycle3240 · reddit · 2026-08-03
A developer compared MiniMax H3 and LTX 2.3 using minimal prompts to test natural movement and authenticity.
Results:
- LTX 2.3: Characters look dead inside with disembodied reactions that mismatch the context.
- MiniMax H3: Movements feel far more human and alive, winning by a striking margin. Drawbacks include unwanted auto-generated subtitles and slight speech stumbling with extremely short prompts.
Conclusion: MiniMax clearly wins in realism, but LTX 2.3 still holds an edge for multi-minute video generation. The author notes LTX will likely be forgotten once a 4-step distilled version of MiniMax is available.
