- The model id is now auto-filled from the model name as you type, and if left
blank it's derived on save (slug of the last path segment, e.g.
"qwen/qwen3.7-max" → "qwen3-7-max") — saving no longer errors on a blank id.
- probe/test auth failures (401 / "User not found" / "No auth") now append a
hint to check the API key (for OpenRouter: use an inference key, not a
provisioning/management key).
