I read about Gemma this morning. It is the open source version of Google Gemini. So I started trying it out locally on my raspberry pi where I already have ollama and ollama-webui. Then I discovered the prompts and modelfiles which I thought were worth a blog post. Modelfile Let’s start with Modelfiles. You can create your own or browse on OllamaHub. It’s genious. It reminds Dockerfile with the initial FROM statement.
