# Model lifecycle

> Learn about Serverless Inference model lifecycle and retirement


This page describes how models in the Serverless Inference catalog move through their lifecycle stages, how W\&B notifies you of upcoming changes, and which models are deprecated or retired. Use this information to plan migrations away from models that are scheduled for removal.

W\&B evaluates and releases new models as part of the Serverless Inference catalog on an ongoing basis.

W\&B reviews older models periodically and may retire them to prioritize the most in-demand and highest-quality offerings.

## Model lifecycle stages

Models in Serverless Inference use the following terminology for the stages of their lifecycle:

* **Experimental**: The model is available for initial experimentation, but isn't bound by our standard SLA or deprecation process.
* **Generally available**: The model is fully supported and recommended for use.
* **Deprecated**: The model is scheduled for removal. Update to a recommended replacement as soon as possible.
* **Retired**: The model is no longer available. Any requests to retired models fail and return an `HTTP 404` status code.

## Deprecation process

When W\&B deprecates a generally available model, we provide at least two weeks of notice on this page before the model is retired.

We also attempt to notify recent users of a deprecated model through email and provide recommendations for replacement models.

Models that are in the **deprecated** stage continue to serve requests.

## Deprecated models
