Contact

Write to contact@minimaxh3tutorial.com. There is deliberately no contact form: plain email keeps your message out of third-party form processors, and the site's only measurement is the analytics described in the privacy policy. Your address is used to reply and for nothing else.

If a figure, a command or a claim on this site looks wrong, say which page and which exact figure or sentence you mean. Confirmed errors are corrected on the affected page with a note, not silently swapped. This applies to measured numbers as much as to prose — the site's evidence rules depend on readers pushing back.

Questions about a MiniMax H3 run that fails are welcome, but an answer is only possible with the environment attached. Include:

• GPU model and VRAM size, plus your operating system.
• ComfyUI version, and whether it was updated recently.
• Which workflow file you loaded (T2V, I2V or R2V, and where it came from).
• The model files in use — filenames are enough.
• The full error text from the ComfyUI console, not a paraphrase.

Check the troubleshooting guide first; several common failures already have step-by-step fixes.

This is an independent documentation site. It cannot help with MiniMax or Hailuo AI accounts, billing on hosted services, or official support for ComfyUI and Hugging Face — those requests belong with the respective vendor. Licensing questions are mapped, with sources, on the license page, but the site does not give legal advice.
