Vertex AI API
Anthropic’s Claude models are now generally available through Vertex AI.
The Vertex API for accessing Claude is nearly-identical to the Messages API and supports all of the same options, with two key differences:
- In Vertex,
model
is not passed in the request body. Instead, it is specified in the Google Cloud endpoint URL. - In Vertex,
anthropic_version
is passed in the request body (rather than as a header), and must be set to the valuevertex-2023-10-16
.
Vertex is also supported by Anthropic’s official client SDKs. This guide will walk you through the process of making a request to Claude on Vertex AI in either Python or TypeScript.
Note that this guide assumes you have already have a GCP project that is able to use Vertex AI. See using the Claude 3 models from Anthropic for more information on the setup required, as well as a full walkthrough.
Install an SDK for accessing Vertex AI
First, install Anthropic’s client SDK for your language of choice.
