ollama - 💡(How to fix) Fix Claude Desktop Cowork 3P Gateway shows only Legacy Model; /v1/models returns 39 models but 0 usable [7 comments, 5 participants]

There's an issue with the selected model (claude-sonnet-4-6).
It may not exist or you may not have access to it.
Run --model to pick a different model.
