# Version Policies

Datalab is designed to be enterprise-ready.

This means that we will not introduce breaking changes for top-level versions
and provide a clear upgrade path for version changes.

## API Policy

For any given API version, we will preserve:

* Existing input parameters
* Existing output parameters

However, we may do the following:

* Add additional optional inputs
* Add additional values to the output
* Change conditions for specific error types
* Add new variants to enum-like output values (for example, streaming event types)

## SDK Policy

The SDK is built on top of the API, so it will follow the same versioning principles.

## Model Output

We frequently update our models to improve accuracy and performance. This can
introduce subtle changes in outputs. At this time, we do not support version
pinning outside of enterprise plans. Contact us at
[support@datalab.to](mailto:support@datalab.to) for information.
