Vertex AI reaches its Claude 3 Haiku shutdown date
Google Cloud's Vertex AI release notes list 23 August as the shutdown date for Anthropic's Claude 3 Haiku, following deprecation on 23 February. The notice points customers to partner-model deprecation guidance but does not name a replacement in the release-note entry.
Why it matters: Workloads pinned to the retired Vertex AI partner model can fail at a hard lifecycle boundary. Migration also changes model behavior, pricing, context, latency, regions, safety, and tool contracts, so an alias swap is not sufficient evidence of parity.
