Arize (arize SDK)

Python SDK for interacting with Arize AX — Arize's enterprise AI engineering platform. IMPORTANT: The 'arize' package covers two separate product tracks with distinct APIs that coexist in the same package. (1) arize.api.Client / arize.ml — the v7 legacy ML monitoring SDK for logging predictions, actuals, embeddings, and drift data to the Arize ML platform. (2) arize.ArizeClient — the v8 LLM/agent observability API for tracing spans, evaluations, and datasets. v7 and v8 are NOT interchangeable. v7 support ends June 1, 2026. Also note: 'arize-phoenix' is a SEPARATE package — Phoenix is Arize's open-source observability tool. Do not conflate arize (enterprise cloud) with arize-phoenix (OSS self-hosted).
