NVIDIA Nemotron 3 Ultra
a serious frontier model whose licence nvidia's own two sets of pages cannot agree on.
capable, long-context and well-engineered — marked down purely because we could not establish, from nvidia's own sources, what you are agreeing to.
the licence file linked from the hugging face card is the linux foundation's openmdw-1.1: no revenue cap, no field-of-use limit, no naming mandate, with an ip-litigation termination clause and responsibility on you to clear third-party rights. read alone, that is reasonably permissive.
but nvidia's own legal-agreements pages describe nemotron models as governed by a custom nvidia nemotron open model licence, effective december 2025, which adds a naming mandate on derivatives and a broad user-indemnification clause that openmdw contains nothing like. we could not determine whether this model was quietly relicensed or the card is mislabelled, and nvidia's materials are inconsistent on it.
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.
