[Feature Request] Support Anthropic Model on Google Vertex

[ryanhex53]

🥰 Feature Description

Currently, I can't get it to work with Claude 3.5 on Google Cloud Vertex AI. Google Cloud offers a $300 no-cost trial credit for 90 days. Could anyone help with this?

🧐 Proposed Solution

Here are some information from google cloud documentation:

Note that the API for Claude on Vertex differs from the Anthropic API documentation in the following ways:

• model is not a valid parameter. The model is instead specified in the Google Cloud endpoint URL.
• anthropic_version is a required parameter and must be set to "vertex-2023-10-16"

request.json
