 This library also provides support for the [Anthropic Vertex API](https://cloud.google.com/vertex-ai?hl=en) if you install this library with the `vertex` extra, e.g. `pip install -U anthropic[vertex]`.
 
 You can then import and instantiate a separate `AnthropicVertex`/`AsyncAnthropicVertexAsync` class, which has the same API as the base `Anthropic`/`AsyncAnthropic` class.
