NVIDIA Cosmos3
the most completely open release in the category
the top open-weight model on artificial analysis, released with datasets and training recipes — if provenance matters to you, nothing else is close.
cosmos3 is the highest-ranked open-weight model on artificial analysis, and nvidia released it properly: checkpoints, six datasets, and the training recipes. most 'open' releases in 2026 mean a weights file and a licence that forbids using it. this one means what the word used to mean.
the openmdw-1.1 licence grants commercial rights, which together with hidream's MIT makes these two the only genuinely shippable open models near the frontier.
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.
