Congrats to the Gemma 4 Challenge Winners!

We are so excited to announce the winners of the Gemma 4 Challenge!

This is officially our most participated-in challenge to date, and the range of submissions made that obvious from the start. We saw a ten-year-old GPU-less laptop pushed to its limits, a $50-a-month OCR bill replaced by a local vision pipeline, disaster scenes compressed into 200-byte emergency payloads, and a phone that notices when an elder living alone needs help. The sheer array of topics and builds made these a joy to read through.

Now, let's cut to the chase and celebrate our winners!

🎉 Congratulations To…

Build With Gemma 4 Winners

This prompt asked builders to put Gemma 4 to work, and the range of what came back was the whole story.

We saw the model packed onto a disaster-relief app for the Philippines that keeps functioning when the cell towers go down, turned into a lanyard-worn pair of eyes for blind and low-vision users, and routed through a strict tool-dispatcher so a 2B model could safely tap and type on someone's behalf. One submission ran entirely peer-to-peer so no prompt ever touched a server, and another distilled a HIPAA-bound DBA's 3 AM database panic into a six-section runbook that never left their laptop.

Across all of it, these projects show Gemma 4 expanding the map what can be built and who gets to use it.

Write About Gemma 4 Winners

The writing prompt covered just as much ground, from practical decision-making to deep architectural breakdowns to honest on-the-ground reporting.

One winner laid out exactly how to pick between Gemma 4's four variants before writing a single line of code, while another went under the hood of the model's vision system to explain how it compresses image patches into soft tokens. A third explored what an agentic Gemma 4 misinformation moderator for the Fediverse would actually have to contend with, a fourth shared the hard-won configuration tricks for getting real speed out of Gemma 4 E2B on Android, and the last took the open-model "catch-up" story to Freetown and tested it against the phones people actually carry.

Taken together, these posts are some of the most useful reference material the community has produced on Gemma 4 yet.
