LLM Prompting Guide

Prompt format rules for generative video and music models. Use when writing or reviewing a prompt for MiniMax H3 (text/image/reference-to-video with native audio) or MiniMax Music 3 (song generation from caption plus lyrics), in ComfyUI or elsewhere. Do NOT use for chat-assistant prompts, or for generative models not named here.

LLM Prompting Guide

The models below were trained on prompts written in a specific labelled structure, and guessing at that structure degrades output. Read the full guide for the model in play before writing any prompt text; the bullet here is a router, not enough to draft from.

  • MiniMax H3 (video + native stereo audio; T2VA, I2VA, FL2VA, L2VA, R2V) -> references/minimax-h3.md
  • MiniMax Music 3 (full songs from a structured caption + tagged lyrics) -> references/minimax-music-3.md
    • Music 3 only responds to styles its training corpus contains. Check every genre term and production phrase before writing: references/minimax-music-3-corpus.md

Adding a model: one bullet above, plus the skills references/<model>.md opening with a table of contents and a mode-selection table.

By default, unless instructed otherwise save your generated outputs to a file in the current working directory named something related to the request.
