Anthropic added a line field to the Models API: GET /v1/models and GET /v1/models/{model_id} now return the model line each model belongs to (e.g. Claude Opus 4.5 and Claude Opus 4.6 both report opus), with line null for models that belong to no line. Developers can use it to group models without parsing their IDs.
