Running MiniMax H3 on 8GB VRAM: Text Encoder Workaround
Zealousideal-Car4724 · reddit · 2026-08-03
A user discussed the feasibility of running MiniMax H3 on a device with only 8GB VRAM and 32GB RAM.
- Core Issue: ComfyUI doesn't reliably offload the text encoder from RAM/VRAM after encoding, causing OOM errors.
- Workaround: If you run it again after the initial error, the text encoder won't need to run a second time, bypassing the resource bottleneck.
- Model Choice: Recommends using Q5KM or FP8 Qwen3-VL as the text encoder alongside the int8 pruned H3 base model.
