My Local Copilot: Gemma 4 + Open WebUI + OpenHands for Coding Without Leaving My Machine

This is a submission for the Gemma 4 Challenge: Write About Gemma 4 Note: this post describes a real local architecture I use for development. Exact model names in Ollama, Hugging Face or Kaggle may vary depending on the runtime you use. The important part is not memorizing one command, but understanding how to separate chat, reasoning, multimodal context, code execution and repositories on your own machine.
