Machine Learning/LiftWing/API - Wikitech

Use the Lift Wing API to access Wikimedia machine learning (ML) models. Lift Wing hosts both experimental and production ML models as inference services that you can query for predictions.

The Lift Wing API offers the following key features:

• Access to predictions from various Wikimedia ML models, via a REST API
• Access to multilingual and language-specific models, for a variety of wiki projects
• Centrally-managed MLOps system and standardized model serving infrastructure

Lift Wing infrastructure, and the models it hosts, replace ORES. To learn more about the differences and how to migrate, see the ORES to Lift Wing migration guide.

You can access Lift Wing model servers through internal or external API endpoints, depending on the model and your access permissions. Use Machine_Learning/LiftWing#Current_Inference_Services to see the list of available models. Models in the "experimental" namespace are only available internally.

• Internal access is for clients internal to the production WMF network. It is not available to Toolforge nor Cloud VPS machines.
• External access is available for all clients, including from the public internet, Toolforge, and Cloud VPS.

Rate limits vary for internal and external users; see the links above for details.

See mw:Wikimedia_APIs/Stability_policy for general API infrastructure policy.

Models available through the Lift Wing API have varying levels of stability, depending on whether they are experimental or in production. There is no unified policy for Lift Wing services, because each service's stability and SLOs depend on its intended use case. Consult the model card to understand the model's existing and intended use cases, along with its freshness. Use the API reference to understand the status of specific endpoints.
