Inkling

thinking machines' first model — apache 2.0, multimodal, and unusually honest about not being the best.

free (apache 2.0)#teams-who-want-a-permiss

the strongest open-weight model from a us lab, built for customisation rather than benchmarks — and its own model card says plainly that it isn't the strongest overall.

released on 15 july, this is the first from-scratch open-weight model from mira murati's thinking machines lab: 975b total with 41b active, trained on 45 trillion tokens spanning text, image, audio and video, with up to a million tokens of context from the downloaded weights.

it is explicitly designed as a customisation base rather than a finished product, paired with the vendor's tinker fine-tuning platform, and its stated design goals include resistance to censorship. the model card's own admission that it is 'not the strongest overall model available today, open or closed' — swe-bench verified at 77.6% against roughly 95% for leading closed models — is the kind of candour this category could use more of.

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

our verdict

the strongest open-weight model from a us lab, built for customisation rather than benchmarks — and its own model card says plainly that it isn't the strongest overall.

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.
