Hi @momo0101 ,

The access to some Anthropic models (like Claude 3.7 Sonnet) could be limited due to high demand. In some cases, these models won’t appear in the UI or you can encounter permission denied error like in your example. This was explain in below thread:

azure databricks Claude/Sonnet endpoints missing - Microsoft Q&A

So, maybe just wait a day or two and try again 🙂 If problem will persists than you can submit ticket to support.
