Slow generation H3 Oct 12

GitHub issue: https://github.com/Comfy-Org/ComfyUI/issues/17015

Not run

MiniMax-H3 generations on an RTX 5070 Ti average 20 minutes (up to 40) for 12 steps at 1 MP, slower since about Oct 12.

What Badgr ran

Nothing was run: the workflow and checkpoints were not attached and the model is large.

What came back

  • The reporter reverted to v0.37.0 without change.

A cloud run of the same workflow would give a time and cost comparison.

Checked 2026-10-14 in Badgr’s local development environment.
