Use a model ID that starts with `gemini-`.' — Imagen removed ## Body Cause (Maintainer-confirmed cause): Changelog 4.0.49 (f607a12): 'drop support for Imagen models and their integration following API shutdown'; GoogleImageModel.doGenerate now rejects any model id not starting with 'gemini-'. Fix status: documented_behavior Misleading approaches: - Pinning an older provider version — the changelog says the Imagen API integration was shut down.
