MiniMax M2.7

announced as open source, then relicensed after release to forbid commercial use without written permission.

free for non-commercial only#research#personal-projects#nothing-you-intend-to-ch

a capable agentic model you cannot ship on. the licence changed after the headlines were written, which is exactly why we read the file rather than the announcement.

the sequence matters. minimax announced 'minimax open sources m2.7' on 12 april, and its previous two models, m2 and m2.5, shipped under standard mit — so the reasonable expectation was more of the same. shortly after release the licence file was revised: commercial use now requires minimax's prior written authorisation, requested by email.

'commercial use' is defined broadly enough to catch almost anything — any paid product or service, commercial api use, and commercially deployed fine-tunes or derivatives. even authorised users must display 'built with minimax m2.7'. a use-restriction appendix additionally bans military applications, illegal content, disinformation and harassment. the hugging face community flagged it immediately as not osi-compliant, and it isn't.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
