Hacktoberfest Hack Day Amman x Jordan Open Source Association (JOSA)

It’s time to see how much you can build with a lightweight, open model. Gemma 4 packs multimodal intelligence into an open-weights model that you can access through the Gemini API. So, what can Gemma 4 bring to your project?

• Multimodal Experience: Work with text and images to create an assistant that understands more of what users share.
• Focused AI Tools: Build a focused AI tool for learning, creativity, productivity, or your community.
• Rapid Prototyping: Experiment with an open model while using the Gemini API to move quickly from an idea to a working prototype.

Bring your idea to life… what will you build with Gemma 4 today?

Build an original project that uses open-source or open-weight AI as an important part of how it works. Teams could create an agent skill, build with an open-weight large or small language model, or build or adapt an open-source model harness. These are examples within one challenge, and teams may combine them.

Open-source or open-weight AI must be an important part of the project.

The project must be published in a public GitHub repository and use an open-source license.

An agent skill must comply with the Agent Skill Open Standard.

A model-harness entry must include an original implementation or meaningful changes to an existing open-source harness.
