01.AI — Provider Intelligence Profile

What this reference supports

01.AI develops the Yi model family, publishing open-weight releases alongside a hosted platform API. 01.AI is a privately held company, founded in 2023 and headquartered in Beijing, China. ModelRefs currently indexes 5 canonical models from 01.AI. 01.AI's indexed lineup includes at least one open-weight model available for self-hosted deployment.

Use this page to check 01.AI's indexed model coverage, open-source posture, and top-scoring tracked capability, then review the Quick Facts panel and the provider implementation reference below for deployment, governance, and pricing detail before comparing it against other providers.

Catalog presence and these figures reflect ModelRefs' own canonical registry, not an external ranking or endorsement. Model coverage and capability scores change as evidence is added, and provider-published claims — compliance, pricing, regional availability — should be confirmed directly with 01.AI before implementation.
