MiniMax H3 ComfyUI

Run a finished MiniMax H3 prompt through ComfyUI using bundled T2V, I2V, R2V, or audio-only workflows. Turbo is the default variant; preserve the selected pinned graph unless the user explicitly overrides a declared field.

Interpret control flags

Recognize these case-insensitive controls anywhere in the request:

For every <boolean> below, accept true, on, yes, or 1 as true and false, off, no, or 0 as false.

• [return=<boolean>]: wait for completion and fetch results when true; submit and return the prompt_id immediately when false. Default true.
• [prompt_enhance=<boolean>], [pe=<boolean>]: improve the prompt through the matching MiniMax H3 prompt specialist when true; preserve it when false. Default false.
• [preview=<boolean>]: show or hide the ComfyUI browser after loading the prepared workflow. This has no effect when load_workflow resolves to false. Default true.
• [load_workflow=<boolean>]: replace the live canvas with the prepared workflow when true. When false, stay headless: do not initialize or open a browser, and do not announce preview or canvas behavior. Default false.
• [turbo=<boolean>]: use the 6-step MiniMax H3 Turbo LoRA workflow when true; use the original 20-step workflow when false. Default true. In particular, [turbo=off], [turbo=no], and [turbo=false] disable Turbo.

Strip control flags before sending text to MiniMax H3. Treat unambiguous natural-language name/value execution settings, such as "use seed 42" or "at 8 sampling steps," as controls and remove only those clauses from the prompt payload. Preserve ambiguous operational wording as prompt text; do not invent a setting from phrases such as "the original sampler."

Match every boolean flag name and value case-insensitively. If the same flag appears more than once, use its last occurrence. Treat any other value as invalid control syntax and stop before workflow preparation.
