Gemma 4 Fine-Tuning in Practice: Preventing Data Starvation, Overfitting, and Quality Problems
A practitioner's guide to Gemma 4 fine-tuning—covering data quality validation, LoRA vs QLoRA selection, overfitting prevention with early stopping, checkpoint selection, and pre-deployment quality evaluation with complete code examples.
Running Multiple Gemma 4 LoRAs in Production — A Practical Guide to Merging and Dynamic Adapter Switching
You've trained three LoRAs on Gemma 4 — one for summarization, one for translation, one for code review. Now the real question: how do you serve them in production without tripling your GPU bill? This is my working notebook on merging and dynamic switching, written with Antigravity alongside.
Tuning Gemma 4 for Yourself — A Realistic LoRA / QLoRA Workflow on a Solo Developer's Budget
Full fine-tuning of Gemma 4 is out of reach for most individuals, but LoRA / QLoRA makes personalization realistic on a solo budget. This guide walks through data prep, training settings, evaluation, and wiring the result into an Antigravity workflow — from hard-earned practical experience.
