Available models

The following models are available for use in Unstructured workflow nodes, organized by model functionality and provider.

The following listings apply to Let’s Go, Pay-As-You-Go, and Business SaaS users of Unstructured Pipelines and API. For dedicated instance and in-VPC deployments, see AI providers.

Use this page to find the model IDs you can set for each workflow node, grouped by node and provider. This information is accurate as of the time of publication and may change as models are added or deprecated. This page does not list deprecated models. If a workflow specifies a deprecated model that has a replacement, Unstructured uses the replacement model instead. If a deprecated model has no replacement, Unstructured rejects the workflow.
