Description
Build with Gemma: GDG Cloud HK - AI-Driven Defense 🛡️🤖 Are you ready to turn bleeding-edge AI security concepts into real-world defensive tools? Whether you are fresh off the insights from the Google Cloud Security Forum Hong Kong on July 15, or a developer eager to explore the capabilities of open-source AI, this hands-on sprint is for you. Join GDG Cloud Hong Kong on Saturday, July 25, 2026, for an intensive day of collaborative hacking, learning, and building with Google’s latest open-weights model: Gemma 4. 🏆 The Challenge: AI-Driven Blue Team Defenses During this day-long developer sprint, your mission is to leverage the advanced reasoning capabilities of Gemma 4 to build next-generation cybersecurity defenses. Together with your team, you will design and deploy critical Blue Team solutions, such as: Autonomous Threat-Hunting Agents: Architect intelligent, self-directed agents capable of analyzing system behavior and identifying potential threats in real-time. Multimodal Architecture Analyzers: Build AI tools that can ingest complex network infrastructure diagrams and cloud-access logs to predict, detect, and neutralize multi-cloud attack vectors. 🚀 Zero LLM Experience? No Problem! Think you need a Ph.D. in machine learning or years of LLM fine-tuning experience to make an impact? Think again. We are completely lowering the barrier to entry so passionate developers of all backgrounds can participate. To help you succeed, we provide: On-Site Cloud Resources: Get direct access to the infrastructure and compute power needed to deploy and experiment with Gemma 4 models. Expert Mentorship: Learn directly from Google Developer Experts (GDEs), industry professionals, and our experienced GDG team members who will be on-site to help you debug and structure your solutions. 🏆 $2,000 USD Prize Pool & Rewards Thanks to our sponsors, we are offering a total cash prize pool of $2,000 USD distributed across five distinct tiers, alongside cloud credits and credentials to accelerate your developer journey: Award TierCash PrizeAdditional Perks🥇 First Place (Grand Prize)$800 USD + Official Winner Certificate🥈 Second Place$400 USD + Official Winner Certificate🥉 Third Place$250 USD + Official Winner Certificate🏅 Fourth Place$250 USD + Official Winner Certificate⚡ Performance Prize$300 USD + Official Winner Certificate 📊 Evaluation Rubric The judging process is designed to be swift and impactful, reflecting the rapid 1-day sprint format of this event. Our panel of experts will evaluate your submissions based on how effectively you utilize Gemma 4 models to build innovative and practical applications.
