Testing MiniMax-H3 T2I on RTX 5090: 12 Mins for a 15s Clip
VirtualWishX · reddit · 2026-08-07
The author tested the Text-to-Video (T2I) capabilities of the MiniMax-H3 model (FL2VA pruned int8) on an RTX 5090 (32GB) system.
- Performance: Generating a 15-second, 0.6-megapixel video at 20 sampling steps took about 12 minutes and 27 seconds.
- Objective: The author intentionally ignored the recommended complex prompt formats (like specifying Subjects and Pictures) to test the model's tolerance and creativity with "freestyle" natural language.
- Prompt Details: The post includes a long, camera-language-heavy prompt describing a cinematic action scene with Arnold Schwarzenegger and Jerry Seinfeld in a white void.
