h3ir/data/qwen25_tokenizer/vocab.json

    The byte-pair-encoding vocabulary from the Qwen2.5 tokenizer, published by
    Alibaba Cloud under the Apache License, Version 2.0.

    It is vendored rather than downloaded because token counts here have to be
    exactly what MiniMax H3's conditioning encoder sees, and H3's own shipped
    vocab.json is byte-identical to this file (git blob
    4783fe10ac3adce15ac8f358ef5462739852c569). Vendoring it makes `h3ir budget`
    exact and offline, with no version of the vocabulary to drift.

Relationship to MiniMax H3
--------------------------------------------------------------------------------

This project is an independent, unofficial implementation of the Context-IR
stage of MiniMax H3. It is not affiliated with, endorsed by, or supported by
MiniMax.

It contains no MiniMax code, weights, or model files. What it implements is the
prompt format described in MiniMax's published H3 prompt guides, together with
behaviour verified against the H3 tokenizer as shipped in ComfyUI. The golden
fixtures under h3ir/golden/ include MiniMax's own published Ref2VA example,
quoted so that the validator can be proved against it.

"MiniMax" and "H3" are the marks of their respective owner and are used here
only to say which format this software targets.

The Apache License above governs this software and nothing else. MiniMax H3
itself is distributed under the MiniMax H3 Community License Agreement, which
carries obligations this licence does not, including a territorial restriction
and a user-interface attribution requirement for commercial use. Anyone running
a model against briefs produced here is bound by that agreement, not by this
one. See the README's licence section, and read theirs.

comfyui/web/tray.js, comfyui/media.py, comfyui/web_api.py

    The media tray's widget sizing and upload idioms, and the technique for
    reading media out of ComfyUI's input tree, are adapted from
    ComfyUI-Fantastic-MiniMaxH3-PromptBuilder by Adudeguyman
    (https://github.com/Adudeguyman/ComfyUI-Fantastic-MiniMaxH3-PromptBuilder),
    published under the MIT License.

comfyui/web/prompt.js

    The prompt editor's state idioms are adapted from ComfyUI-MiniMaxH3-Easy
    by nkxx188 (https://github.com/nkxx188/ComfyUI-MiniMaxH3-Easy), published
    under the MIT License.

    The technique for drawing the mentions -- a mirror element behind a
    textarea whose own text is transparent, with the marks on a mention paid
    for in outer box-shadow so they occupy no room in the line -- is adapted
    from ComfyUI-Fantastic-MiniMaxH3-PromptBuilder by Adudeguyman
    (https://github.com/Adudeguyman/ComfyUI-Fantastic-MiniMaxH3-PromptBuilder),
    published under the MIT License. The same pack's hit-testing of those
    marks through the textarea above them is what makes hovering one show the
    file it names.
