Google Gemma 4 — Free Open-Source AI That Codes Locally on Your GPU

Watch the Full Setup

Google just dropped Gemma 4 — an open-source AI that codes, runs locally on your GPU, and is completely free. No API, no cloud, no cost.

What Is Gemma 4?

Released by Google DeepMind, Gemma 4 is a 26 billion parameter model with impressive specs:

Mixture of Experts (MoE) — only activates 4B parameters at a time, making it fast and efficient
256K context window — handles massive codebases and long conversations
Native function calling — built for agentic workflows (works with OpenClaw and other agent tools)
Apache 2.0 license — fully open source, use commercially, build products with it
Single GPU — runs on any 24GB GPU (RTX 3090 or equivalent)

Setup (One Command)

1. Install Ollama

curl -fsSL https://ollama.com/install.sh | sh

2. Start Ollama

ollama serve &

3. Pull and Run Gemma 4

ollama pull gemma4:26b
ollama run gemma4:26b

That's it. Gemma 4 is running locally, fully responsive, ready for coding tasks.

What It Can Do

Test 1: Writing Async Python

I asked it to write a function that takes a list of URLs and returns their HTTP status codes concurrently using asyncio, with error handling and type hints. Clean code, proper structure, saved automatically.

Test 2: Bug Finding and Fixing

I gave it broken code for merging sorted arrays that fails with different-length arrays. It found the bug, explained why it fails, and provided the fix. All locally, no API call.

Test 3: Building a Landing Page

I asked for a modern landing page with Tailwind CSS — hero section with gradient, features grid with three cards, footer, dark theme, responsive. It generated a complete, professional page with animated cards.

Why This Matters

Five months ago, this level of AI coding intelligence cost money and required cloud APIs. Today, Google open-sourced a model that:

Outperforms models 20x its size
Runs on a single consumer GPU
Has a 256K context window
Supports native function calling for agentic workflows
Is Apache 2.0 — zero restrictions

Use it commercially, build products with it, integrate it with OpenClaw or any agentic tool — all for free, forever.
