Claude Sonnet 4 (APAC) deprecated

Amazon has deprecated the APAC-hosted version of Anthropic's Claude Sonnet 4 model, identified as apac.anthropic.claude-sonnet-4-20250514-v1:0, which was released on 2025-05-22 and now carries no announced retirement date. The model supports text, image, and PDF input with a 200k context window and 64k maximum output. The deprecation affects developers whose code calls the APAC endpoint, and the provider announcement is linked via models.dev.
