The Truth Behind MiniMax 2x Speedup: Newer Python Dependencies Introduced convrot Support

lmpdev · reddit · 2026-08-07

There has been controversy in the community regarding whether the INT8 acceleration node in ComfyUI actually provides a 2x speedup for MiniMax models. Some users saw significant gains, while others saw nothing or even experienced CUDA driver crashes.

Developer lmpdev discovered through investigation that the real reason for the speedup is not the acceleration node itself, but the version of the underlying Python dependencies. After reinstalling dependencies in a fresh conda environment (Python 3.13), the same speedup was achieved using only the official template. The hypothesis is that recent dependency updates (like PyTorch) introduced convrot support, and the users who previously experienced speedups simply had outdated library versions.
