Side-by-side evidence from this catalog. This is not a leaderboard: no column measures capability, safety, or which organization is “ahead.” Every number links to exactly the records it counts.
Model releases view
Rows are organization records with a documented hosted-model product or at least one model record. Hosted model products come from sourced product records on each organization page (a product indicator, not a release count). All other columns count model records in the Open Models & Tools directory.
Tier columns use USASI rubric v0.1 and are cumulative, so they overlap: every fully open release is also counted as open-stack and open-weight. Do not add them together. A release listing two organizations appears in both rows, so columns are not summed.
- Model families
- Family overview records. Families summarize releases and are never counted as releases.
- Model releases
- Specific releases assessed in this catalog.
- Open-weight
- Releases with publicly downloadable weights. Includes every open-stack and fully open release.
- Open-stack
- Subset of open-weight releases that also publish code, recipe, and training-data information. Includes fully open releases.
- Fully open
- Subset of open-stack releases meeting every item of the rubric.
- Training code public
- Releases whose training code is documented as public.
- Training-data info
- Releases whose training data is public, or whose composition is documented (public or partial).
- Evaluation materials public
- Releases whose evaluation code or prompts are published, so others can re-run the evaluations. Results-only releases are not counted.
- Restricted weights
- Releases whose weights are available only by request or approval, or to some users. Not counted as open-weight.
- Weights unassessed
- Releases whose weight availability is Unknown in this catalog.
- Zero versus unknown
- 0 means no matching published record in this catalog — not proof that nothing exists. “Weights unassessed” counts releases whose weight availability is Unknown.
- What is excluded
- Drafts and archived historical records are excluded from every count.
Software, data & evaluation view
Each kind of artifact is compared on its own checklist. Status is shown with an icon and text; Unknown means unassessed or insufficient evidence.
