[ISSUE] cannot deploy foundation models provisioned throughput endpoint via sdk

[marianreuss]

Description
I'm trying to deploy a gpt-oss-120b provisioned throughput endpoint via the sdk (0.69.0). I then run into the following error:

databricks.sdk.errors.platform.InvalidParameterValue: Served entity system.ai.gpt-oss-120b is not eligible for Provisioned Throughput.

However, deploying the foundation model via the UI works just fine.

Reproduction

from databricks.sdk import WorkspaceClient
from databricks.sdk.service.serving import EndpointCoreConfigInput, ServedEntityInput

w = WorkspaceClient()

w.serving_endpoints.create_and_wait(
    name="pt_endpoint",
    config=EndpointCoreConfigInput(
        served_entities=[
            ServedEntityInput(
                name="foo",
                entity_name="system.ai.gpt-oss-120b",
                scale_to_zero_enabled=False,
                entity_version=1,
                min_provisioned_throughput=10,
                max_provisioned_throughput=100,
        )
        ]
    )
)

Expected behavior
The model serving endpoint is deployed.

Is it a regression?
Not that I know of. Tested some older versions, same result.
