GlennHasABeard finds MiniMax H3 holds four objects better than six in local tests
GlennHasABeard's local ComfyUI tests held four objects more reliably than six and failed to recognize a butter curler. Locked-camera clips also tested motion direction before Topaz upscaling to 4K.

TL;DR
- Four ice houses held together where six had failed, GlennHasABeard reported in his ice-tray test.
- An unfamiliar butter curler caused trouble; he replaced it with a knife for the seashell curls.
- Local ComfyUI rendering was followed by Topaz upscaling to 4K in the moon-scoop clip.
- Motion prompts specified direction and timing, from tips-first scissors to a two-second stamp press.
Dough turns into a striped knitted scarf at the pasta-machine rollers. GlennHasABeard also kept a pencil-sharpener take that produced straight stairs instead of the requested spiral.
ComfyUI to 4K
GlennHasABeard’s household tests used:
- Camera: locked, with the viewpoint chosen for each action, including overhead and desk-height shots.
- Generation: 14 or 15 seconds, rendered locally in ComfyUI using what he identifies as open-weight MiniMax H3.
- Finish: Topaz upscaling to 4K.
MiniMax’s H3 model card lists generation up to 15 seconds and 2K resolution. Comfy’s model hub also catalogs a local H3 variant.
He separately shared a panning coastal scene without naming its model or settings.
Four ice houses
GlennHasABeard reduced his absurd little housing development from six houses to four:
- Six houses: one take grew an eight-cell tray; another left two cubes without roofs.
- Four houses: a single row held together. The prompt requested clear ice, pitched roofs, and warm interior lights.
Familiar tools and keeper takes
- Butter knife: GlennHasABeard said the model was unfamiliar with a butter curler, so he switched to a knife for the seashell-shaped butter curls.
- Typewriter: he added “No letters or ink marks appear” to the daisy prompt to suppress ordinary typing.
- Hole punch: the device’s shape remained wrong, but he kept the take because the ladybugs emerging from the paper worked.
- Pencil sharpener: the requested spiral became a straight flight. He kept the stairs because they emerged from the blade slot where a shaving belonged.
Motion direction
- Scissors: early takes advanced handles-first. The revised prompt specified “tips in front, handles trailing, uncut paper always ahead.”
- Moon scoop: he gave the scoop one stroke toward the camera rather than a generic scooping action.
- Pressure washer: the patio reveal requested four passes, all left to right. He later said the first two stripes went wrong and that H3 “really has a problem with exact numbers.”
- Paintbrush: “Only ever travels upward while touching the wall” constrained the meadow reveal, preventing the back-and-forth scrub that he said smeared the transformation.
Material boundaries
- Pasta rollers: dough stays above the rollers; wool emerges below. GlennHasABeard explicitly named the machine as the point where the material changes.
- Whisk: a straight-up exit from the bowl pulls the summit into shape in the snowy-mountain prompt.
- Pillow: the escaping fog received an explicit depth and direction in the pillow scene.
Hold times
The wax stamp was prompted to stay pressed for two seconds before lifting. GlennHasABeard said that hold made the reveal feel earned.
For the toaster, he credited an uneventful wait before the pop with making the clunk land.
H3-Context-IR
MiniMax’s open-source announcement describes H3-Context-IR, a system that refines multimodal instructions into an intermediate representation before generation. The company calls it critical to final output quality, but excludes it from the open-source release because it depends on a multistage workflow and hosted models and services.
MiniMax offers an API to reproduce the behavior of its official workflow.
