Corrected 2026-10-24 - see C3-B1044-01; the original statements below are kept for history and are superseded where the correction says so. The MiniMax-AI/MiniMax-H3 GitHub repo (head d21241f0, 2026-08-15) links Hugging Face weights and a "MiniMax H3 Community License" (custom, not OSI; GitHub detects no licence). Its README states the H3-Context-IR preprocessing workflow is not in the open-source release (an API reproduces it), the initial release offers full-attention inference only (sparse attention later), and the H3-Encoder uses the full Qwen3-VL-32B weights (layer-50 hidden states), implying a heavy local footprint. It also ships an "h3-prompt-writing" agent skill (Markdown) usable in Claude Code and other harnesses. This reconciles creator claims: Mikkel Lassalle presented H3 as a hosted, cheaper-than-Seedance model (C3-B335-08); Mickmumpitz called it "free open-source" and used it for video cleanup (C3-B338-02).

This reconciles creator claims: Mikkel Lassalle presented H3 as a hosted, cheaper-than-Seedance model (C3-B335-08); Mickmumpitz called it "free open-source" and used it for video cleanup (C3-B338-02). Both are partly true: open weights under a community licence, plus hosted API.

Curator correction 2026-10-24 (discovery audit record C3-B1044-01, curator-reviewed C3R-0688; excerpts re-located by independent curator GET 2026-10-24): Correction. Served record C3-B338-03 (written 2026-10-23) described MiniMax H3 as open weights under a custom community licence, said the licence text was not read, and listed no territorial limit. The licence omitted by that record says “Applicable Territory” means worldwide, excluding the Excluded Territories, and “Excluded Territories” means the European Union, the United Kingdom, the Republic of Korea and the United States of America; the grant is made solely within the Applicable Territory, and the licence says use, distribution or display of the Works or their Outputs or results outside the Applicable Territory is not authorized. Dates: the LICENSE file at the Hugging Face repository's initial commit (2026-08-03) and at main when fetched (2026-10-24) are byte-identical (same SHA-256), and the licence states a licence date of August 2, 2026, so the condition existed well before the record was written and the record is materially misleading for anyone deciding whether they may use H3 in those territories. Conditions. Applies to anyone in or serving the Excluded Territories; the licence also says persons there may contact MiniMax about obtaining a separate licence. Inference: because the restriction covers Outputs and results, whether it limits where generated clips may be shown is a question for the licence text and counsel, not settled here. Failure modes. Treating the hosted-API versus open-weights distinction as the only gate; assuming a community licence is worldwide. Limitations. This is a summary of one licence file, not legal advice; the licence also contains other terms (acceptable use policy, distribution conditions) not summarised here. Only the LICENSE file was compared; no other HF repository files were checked. Version/date. LICENSE dated August 2, 2026; fetched 2026-10-24.

Curator qualifications: All documentation excerpts located on the live pages by curator GET 2026-10-23; video metadata (title/date/length) checked where cited. 'Implying a heavy local footprint' is discovery inference (VRAM not stated in the lines read). The reconciliation of creator claims (C3-B335-08, C3-B338-02) is discovery synthesis. Licence text itself not read.

Limitations: Licence text itself not read; VRAM not stated in lines read.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
