Suggested reviewers: Merge Risk: 🟡 Moderate · up to This refactor moves model consumers to typed HTTP clients, but the current head can abort job polling on transient HTTP 5xx responses, return a response wrapper where callers expect job data, and leave related retry or refresh error paths inconsistent.

- Around line 19-21: Update the test fixture inputs in
test_strip_type_checker_comments so the sdk.models calls use the adapted
client_from_platform calls expected by the assertions, including the cases
referenced around lines 38-39, while preserving the existing ty: ignore comments
and expected conversion behavior.
In `@services/core/models/src/nmp/core/models/sidecars/adapters/main.py`:
- Line 18: Update the fileset existence-check method to catch the legacy SDK’s
nemo_platform._exceptions.NotFoundError raised by self._sdk.files, or migrate
the calls to self._files so the existing plugin exception handling applies;
preserve the behavior of returning False when the fileset is missing.
In `@services/core/models/tests/integration/test_models_with_auth.py`:
- Line 27: Update the authentication assertions in the tests to use the legacy
client’s PermissionDeniedError for viewer_sdk.inference.* calls. Import that
exception under a distinct alias and use the alias in the relevant pytest.raises
blocks, while leaving the existing plugin error import for other assertions.
In `@tests/agentic-use/guardrails-content-safety-cli/environment/setup-mock.py`:
- Around line 26-29: Update setup() to import and alias the SDK and plugin
ConflictError types separately. Catch the SDK ConflictError around
sdk.inference.providers.create() reconciliation, and catch the plugin
ConflictError specifically around ModelsClient.create_model(), preserving
existing rerun behavior.

Migrate models API call sites from sdk.models.* (Stainless SDK) to client_from_platform(sdk, ModelsClient).* (typed HTTP client), following the pattern established in #1277. 22 files changed across e2e tests, services, plugins, and test utilities. Key migrations: - sdk.models.retrieve -> get_model().data() - sdk.models.create -> create_model(body=CreateModelEntityRequest(...)).data() - sdk.models.update -> update_model(body=UpdateModelEntityRequest(...)).data() - sdk.models.list -> list_models(...).items() - sdk.models.wait_for_openai_model -> wait_for_openai_model(...) - sdk.models.get_provider_route_openai_url -> get_provider_route_openai_url(...) - Error imports: APIStatusError->NemoHTTPError, APIConnectionError/APITimeoutError->NemoTransportError - Type imports: nemo_platform.types.* -> nemo_platform_plugin.models.types.* Skipped (SDK infrastructure, not consumers): - packages/models/src/models/resources.py (extended ModelsResource, deleted with SDK) - packages/models/tests/test_client.py (tests SDK infrastructure) - Auto-generated CLI files (4 files) AIRCORE-827 Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
The models migration moved production call sites to client_from_platform(sdk, <TypedClient>), but the unit test doubles were still shaped like the legacy Stainless sdk.<area> resource. A bare Mock() or SimpleNamespace has no private _custom_headers attribute, so client_from_platform raised and the clients' create/update/list calls were silently lost (surfacing as confusing 'Called 0 times' assertions). Reshape each double around the typed client and route client_from_platform at it: - controllers conftest: mock AsyncModelsClient factory plus a client_from_platform patch that dispatches by module, and a seed_entity_cache that pages via list_models(...).items(). - provider/deployment reconcilers, entity cache, models controller, adapters controller: assert on create_model/update_model/get_model/ list_models body kwargs instead of the legacy sdk.models resource. - evaluator/auditor test doubles: return .data()-bearing responses from client_from_platform mocks. - safe-synthesizer jobs: return an AsyncModelsClient mock for the classify-provider route instead of the files client. - code generator: assert the typed client code string. - workspace IAM isolation: upload via typed FilesClient.upload_file (path/name) rather than legacy upload_content with remote_path/fileset. No assertion was weakened: each key assertion was verified to fail when its expected value is wrong. Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
- e2e/agents_deploy_helpers.py: revert wait_for_openai_model back to the Stainless sdk.models helper. It is a polling convenience method on the legacy resource, not a typed endpoint, so ModelsClient has no such method and the migration's reroute broke agent deploy/invoke e2e tests. - test_models_with_auth.py: the migration swapped every pytest.raises to the plugin PermissionDeniedError, but the provider/deployment_config/deployment calls still go through the unmigrated Stainless sdk.inference resources, which raise the Stainless PermissionDeniedError. Restore a Stainless alias and expect it for those 19 tests; the typed ModelsClient/SecretsClient tests keep the plugin error. Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
…tion CodeRabbit flagged several catch blocks left inconsistent by the models migration: the migration switched imports to the plugin error hierarchy while some guarded calls stayed on the legacy SDK, making those catches no-ops that let the wrong error class propagate. The legacy nemo_platform errors and the plugin NemoClientError-derived errors are separate classes, so each call site must catch what it actually raises. Restore legacy errors for the calls that remain on the legacy SDK (inference providers/gateway/deployments, files) and keep plugin errors for typed clients (ModelsClient, FilesClient, JobsClient): - e2e/test_evaluator_plugin.py: revert error aliases to legacy imports (they guard legacy add_mock_provider and gateway.model.post). - inference-gateway model_cache.py: model_provider_getter stays legacy (inference.providers.list); model_entity_getter uses plugin errors. - adapters main.py: download_fileset catches legacy NotFoundError. - 4x agentic-use setup-mock.py: catch legacy ConflictError for the legacy providers.create; keep plugin ConflictError for create_model. - model_spec run.py: catch plugin NemoClientError (legacy NeMoPlatformError is dead now that get_model/update_model are typed). - e2e customizer.py: catch NemoTransportError from typed JobsClient, which wraps httpx transport errors, instead of the raw ones. - nemo_nb strip test: fixture now matches the client_from_platform assertions the converter produces.
