Google Cloud PlatformGenerative AI models maintenance policy
This article describes the model maintenance policy for the Foundation Model APIs pay-per-token and Mosaic AI Model Training offerings.
In order to continue supporting the most state-of-the-art models, Databricks might update supported models or retire older models for the Foundation Model APIs pay-per-token and Mosaic AI Model Training offerings.
Model retirement policy
The following retirement policy applies only to supported chat and completion models in the Foundation Model APIs pay-per-token and Mosaic AI Model Training offerings.
If a model is set for retirement, Databricks takes the following steps to notify customers:
A warning message displays in the model card from the Serving page of your Databricks workspace that indicates that the model is planned for retirement.
A warning message displays in the dropdown menu for Mosaic AI Model Training in the Experiments tab that indicates that the model is planned for retirement.
Applicable documentation contains a notice that indicates the model is planned for retirement and the start date the model will no longer be supported.
After customers are notified about the upcoming model retirement, Databricks will retire the model in 3 months. During this period of time, customers can choose to migrate to a provisioned throughput endpoint to continue using the model past its end-of-life date.
See Retired models for a list of currently retired models and planned retirement dates.
Model updates
Databricks might ship incremental updates to pay-per-token models to deliver optimizations. When a model is updated, the endpoint URL remains the same, but the model ID in the response object changes to reflect the date of the update. For example, if an update is shipped to meta-llama/Meta-Llama-3.1-405B on 3/4/2024, the model name in the response object updates to meta-llama/Meta-Llama-3.1-405B-030424. Databricks maintains a version history of the updates that you can refer to.
