ML Model Versions

Every change to an ML model entity creates a new version. Use these endpoints to view the version history and retrieve specific versions.

​
List Versions

​
id
string
required
UUID of the ML model.

​
Get Specific Version

Use GET /v1/mlmodels/{id}/versions/{version} to retrieve a specific version.
​
id
string
required
UUID of the ML model.
​
version
string
required
Version number to retrieve (e.g., 0.2).

Returns

List versions returns an object with entityType and a versions array of serialized entity snapshots (newest first). Get specific version returns the full ML model object as it existed at that version.
