Gemma is an open-source large language model (LLM) toolkit that allows you to customize pre-trained models for specific tasks. Use intellinode python module to fine tune the model and integrate with stable diffusion.
Hate to say it but given Google's reputation, why would anyone use their models? Even the open source ones? If it's anything like the others, it's worse than the competition and built from the ground up with authoritarian progressive (read: "woke") safety guardrails because the overlords out there think they know better than you.
