Error: "Invalid model name" in Databricks AI Gateway when setting up Vertex AI endpoint

Hi everyone,

I'm trying to set up a new serving endpoint in Databricks using Google Cloud Vertex AI as the provider. I want to route it to claude-opus-4-6.

However, as soon as I try to create it, I get the following UI error (see screenshot):

"Invalid model name: claude-opus-4-6. Please refer to docs for supported models for VertexAI."

Has anyone successfully deployed this specific model via Databricks Model Serving? Do I need to use a specific versioned string (like @2026...), or is this model simply not yet supported by the Databricks AI Gateway / Serving allowlist? Could you add it to the allowed list? 😉

Any hints on the correct naming convention would be greatly appreciated! Thanks!
