MiniMax released H3-Image, a 33.1-billion-parameter open-weight image model, on 10 November 2026, under a community licence that does not grant rights in the European Union, the United Kingdom, the Republic of Korea or the United States of America. For a university in any of those places, the weights can be downloaded but the licence does not authorise using them there.
What MiniMax released
The MiniMax-H3-Image model card on Hugging Face describes the diffusion transformer as 33.1B parameters, a dense single-stream transformer with 50 layers, paired with a Qwen3-VL text encoder. AI Weekly describes it as a unified model that does both text-to-image generation and image editing from a single checkpoint, with roughly 16-megapixel native output and editing from up to 16 reference images. Crypto Briefing reports the release date as 10 November 2026; the model card itself carries no date.
The weights are published as an open-weights model, meaning the trained parameters can be downloaded, but they are governed by the licence rather than an open-source licence such as Apache 2.0. See the CASRAI entry on open-weights models for why that difference matters.
What the licence says about territory
The MiniMax-H3-Image Community License Agreement works through defined terms. Section I.3 defines the Applicable Territory as worldwide, excluding the Excluded Territories. Section I.5 names the Excluded Territories as “the European Union, the United Kingdom, the Republic of Korea and the United States of America.” The Section II grant is “Solely within the Applicable Territory, we grant you a non-exclusive, non-transferable, royalty-free, limited license.”
Section V.4 closes the loop on outputs: you may not use, reproduce, modify, distribute or display the MiniMax-H3-Image Works “or any of their Outputs or results outside the Applicable Territory.” The licence is governed by the laws of the Hong Kong Special Administrative Region of the People’s Republic of China (Section IX.1).
MiniMax’s separate licence Q and A for the related MiniMax-H3 model says the restriction is not about excluding specific countries and that the limitation means “not yet”, not “not ever”. It adds that organisations in these regions can apply for a formal licence, which MiniMax may approve after reviewing the deployment and confirming safeguards. That Q and A covers H3, not H3-Image, so treat it as indicative only.
Commercial conditions that also apply
Section IV.1 requires a separate, prior written authorisation from MiniMax, requested through its licence console, “if the Annualized Revenue of you and/or your affiliates exceeds 1 Million USD,” or if you provide Hosted Services to Third Parties. The licence defines a Hosted Service as a service through which the model or its derivatives is hosted or operated and its functionality is made available to third parties, including through APIs or web access. The Acceptable Use Policy in Exhibit A is incorporated by reference and prohibits, among other items, use for military purposes.
The licence contains no research, academic or non-commercial exemption. Section VI.1 says you own the derivative works and modifications you create, subject to MiniMax’s rights in the underlying works.
What this means for university researchers
This section is the editorial reading of the licence text above, not legal advice.
- Researchers in the excluded jurisdictions. The grant applies only within the Applicable Territory, and the licence contains no academic carve-out. A lab located in the US, EU, UK or South Korea should not assume that research use is permitted; the route the licence points to is a written authorisation request.
- Outputs and publications. Because Section V.4 reaches Outputs as well as the weights, a team that generates figures or datasets with the model needs to ask the research office whether publishing or sharing them from an excluded jurisdiction is covered. The licence text does not say.
- Collaborations. Multi-site projects with partners in and outside the excluded jurisdictions make the location of each use a compliance question. The CASRAI entries on export-controlled research and AI export controls cover a different legal regime, but the same habit applies: record where the work is done.
- Building on the model. Fine-tuned derivatives stay within the licence, so territory limits and the Section IV triggers follow the derivative. Hosting a derivative for third parties, including through a lab-run API, triggers Section IV.
- Reproducibility. A study that depends on these weights cannot be replicated by colleagues in the excluded jurisdictions without authorisation, which belongs in the methods and data-availability statements.
For a comparable recent release with a very different licence, see CASRAI’s note on Inkling 2 Small, which is released under Apache 2.0.
What to check before relying on the model
Read the full licence and the Acceptable Use Policy rather than a summary, and ask the research office or legal counsel which entity is the licensee. Confirm the model card still shows the same licence text on the date you start, since terms can change between releases.
