UPDATE: Google has officially launched the highly anticipated “Vibe Code with Gemini 3 Pro” competition, offering an astounding $500,000 prize pool in Gemini API credits. This intense developer challenge, hosted on Kaggle, kicks off today, December 5, 2025, and runs for just seven days, concluding on December 12, 2025.
This unique competition invites developers worldwide to harness the capabilities of Google’s latest reasoning model, Gemini 3 Pro, in a sprint that emphasizes speed and creativity. Participants must innovate rapidly to tackle real-world problems across six categories: Science, Education, Accessibility, Health, Business, and Technology.
Why does this matter? With only a week to ideate, build, and submit projects, developers are pushed to fully leverage the power of Gemini 3 Pro, which has been hailed for its superior performance in large language model (LLM) benchmarks. This is not just a contest; it represents a bold move by Google to attract top talent in a fiercely competitive AI landscape.
Gemini 3 Pro, launched in November 2025, has already outperformed competitors like OpenAI’s GPT-5 Pro in 19 of 20 benchmarks, including a remarkable 41% accuracy on Humanity’s Last Exam. The model’s advanced features enable complex, multi-step tasks, making it an ideal tool for developers looking to push boundaries.
“We want to see real-world impact and clever use of our technology,” stated a representative from Google DeepMind.
Participants are required to create projects that go beyond simple scripts or chatbots. Judges will assess submissions based on criteria such as real-world impact (40%), innovative use of Gemini 3 Pro (30%), creativity (20%), and presentation quality (10%). Each submission must include a dynamic two-minute video demo that highlights the project’s “wow” factor.
In a strategic push to dominate the hackathon scene, Google’s $500,000 prize pool dwarfs offerings from competitors, such as Microsoft’s AI Agents Hackathon with $20,000 in cash prizes. This marks a significant effort by Google to solidify its leadership in AI development and attract developers to its ecosystem.
The prize distribution is equally compelling: the top 50 finalists will each receive $10,000 in Gemini API credits, providing ample resources to scale their projects into viable startups. This initiative not only supports developers financially but also encourages innovation and creativity in AI-driven applications.
Developers will utilize tools like Google AI Studio and Antigravity, the new agent-first IDE, to streamline their workflow. Antigravity allows for task-level orchestration, enabling developers to focus on high-level intent rather than line-by-line coding.
This moment is a pivotal opportunity for developers interested in mastering the emerging practice of “vibe coding,” where they articulate their vision, and the AI manages the coding intricacies. Google’s competition exemplifies the shift in software development towards AI-enhanced collaboration.
With the clock ticking, developers are urged to act fast. This competition is not just about winning a prize; it’s a chance to gain experience with cutting-edge technology and build a standout project for their portfolios. Visit the Kaggle page now to participate: Kaggle Gemini 3 Competition.
