Vertex AI SDK (Python)

Google Cloud Vertex AI SDK for Python. Two separate PyPI packages exist: google-cloud-aiplatform (GAPIC clients, full Vertex AI platform) and vertexai (higher-level SDK, same underlying package). Install is google-cloud-aiplatform, import is vertexai — classic name mismatch. Generative AI modules (vertexai.generative_models, vertexai.language_models, etc.) deprecated June 24, 2025 and will be removed June 24, 2026. Current version: google-cloud-aiplatform 1.142.0 / vertexai 1.71.1.
