Hi @zuyezheng,
Welcome to Google Cloud Community!
To request access to Anthropic’s Claude models on Vertex AI, you’ll need to fill out a form with details like your Google account and Google Cloud project ID. According to the request form access to Anthropics’s Claude models on Vertex AI is subject to approval by Anthropic.
See image below for reference:
You can also check the following consideration that might help you resolve the error:
- Check GCP Project - Ensure that you have selected the correct GCP project in the Vertex AI console.
- Marketplace API - Ensure the Google Cloud Marketplace API ( cloudcommerceconsumerprocurement.googleapis.com ) is enabled for your project. You can do this in the Google Cloud Console under APIs & Services > Library .
- Permissions - Make sure you have the necessary permissions to enable and use partner models.
For more information about using Anthropic’s Claude models, you can read this documentation.
If the issue persists, I suggest contacting Google Cloud Support as they can provide more insights to see if the behavior you’ve encountered is a known issue or specific to your project.
I hope the above information is helpful.
