Can't find model '{model_name}' in Database. Access group ma

Error message

Can't find model '{model_name}' in Database. Access group management is only supported for database models.

What it means

Prerequisite guard in access-group management: the requested model_name has no rows in the LiteLLM database (PrismaModelTable), so there is no deployment to tag with the access group. Access groups only apply to DB-stored models, not config.yaml models.

Solutions

1. Create the model in the database first (POST /model/new), then manage its access group.
2. Access groups only work for database models, not config-file models.
