Google offers hosting of various models as a service. To utilize this service you need to use custom end point.
For example for Claude 3.7 Sonnet:
- Enable Claude 3.7 Sonnet Service.
- Click View Code.
- Copy starting with "projects" for example: "projects/$PROJECT_ID/locations/$LOCATION/publishers/anthropic/models/$MODEL"
- Use this URL to configure custom model and enter in the field for Custom Endpoint.
- When Custom Endpoint used, we will replace PROJECT_ID and REGION with correct values.
