US AI Models & US-Operated Providers

Send a request to one of these and the operator is a company headquartered in the United States — head office, not place of registration. Privacy tier is a separate column: it is the highest bar we have recorded from that provider's published policy.

Every provider's full policy note and route list is on its own page. 29 providers in the catalog publish no operator TrustedRouter could pin down, so they appear in no jurisdiction list on this site and no request preference treats them as matching one. Review every provider.

Grouped by the lab that built the weights, with the source TrustedRouter read that from. The operator columns show who runs the endpoints for each route, which is a different question from the lab's country and frequently a different answer.

Model origin is keyed by the vendor prefix of a model id, and a prefix earns a row once at least three of its models are in the catalog. 42 callable catalog models sit under a prefix below that line and carry no recorded origin, so they are on no page here rather than assigned a country by guesswork.
