## Description Document the built-in `google_anthropic_vertex` provider so Deep Agents Code users can configure ADC, project/location settings, the `vertex` extra, and the correct model spec. This also distinguishes Anthropic's Messages API transport from Google's Vertex provider. ## Test Plan - [x] Run Vale and codespell on the updated provider guide Related implementation: langchain-ai/deepagents#5760 Made by [Open SWE](https://openswe.vercel.app/agents/979e343f-42ad-580d-ab0a-69827de47d40) --------- Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>

Closes #4489
dcode --model google_anthropic_vertex:claude-sonnet-4-6now works with GCP ADC whenGOOGLE_CLOUD_PROJECTandGOOGLE_CLOUD_LOCATIONare configured.Claude on Vertex uses Anthropic's Messages API rather than Google's
generateContenttransport, so it needs a separate provider fromgoogle_vertexai. This reuses LangChain's existinggoogle_anthropic_vertexregistry name and integration.Made by Open SWE
