 The infrastructure for deploying connectors can be managed by Elastic or self-managed. Managed connectors require an {enterprise-search-ref}/server.html[Enterprise Search] server connected to the Elastic Stack. Self-managed connectors are run on your own infrastructure and don't require the Enterprise Search service.

 To create the embeddings needed by the AI Assistant (weights and tokens into a sparse vector field), you have to create an *ML Inference Pipeline*:
 +
 .. Open the previously created connector and select the *Pipelines* tab.
 .. Select *Copy and customize* button at the `Unlock your custom pipelines` box.
 .. Select *Add Inference Pipeline* button at the `Machine Learning Inference Pipelines` box.
-.. Select *ELSER (Elastic Learned Sparse EncodeR)* ML model to add the necessary embeddings to the data.
+.. Select your preferred machine learning model such as ELSER or E5.
 .. Select the fields that need to be evaluated as part of the inference pipeline.
 .. Test and save the inference pipeline and the overall pipeline.
 . Sync the data.

 Once the pipeline is set up, perform a *Full Content Sync* of the connector. The inference pipeline will process the data as follows:

-* As data comes in, ELSER is applied to the data, and embeddings (weights and tokens into a sparse vector field) are added to capture semantic meaning and context of the data.
