This update introduces a significant breaking change: the projects.locations.agents.patch method now returns a GoogleLongrunningOperation instead of the Agent resource directly. Developers must update their integration logic to poll the operation for completion. Additionally, the data field in the GoogleCloudAiplatformV1beta1A2APart schema has changed from object to any, which may impact strictly typed client implementations.
On the feature side, experimental video generation now supports 'Pro Edit' via CloudAiLargeModelsVisionGenerateVideoExperimentsProEditConfig. This allows developers to modify existing video generations using text instructions or structured prompts by referencing a fromOperationId. For production monitoring, the Agent resource now includes an observabilityConfig to enable OpenTelemetry spans for tracking tool usage, model latencies, and token counts. Finally, Reasoning Engines now support a revisionGarbageCollectionStrategy to automatically manage resource bloat by keeping only the latest N runtime revisions.
