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.
