Southern Cross AI
Building sovereign AI capability from the ground up.
Southern Cross AI is an independent open-source initiative building models, datasets, and a hands-on technical community for Australia and allied nations.
We are building in the open so researchers, developers, students, institutions, and sponsors can contribute.
Models, datasets, and a builder community.
Southern Cross AI is building practical open-source foundations for sovereign AI: regional language models, sovereign datasets, and a community of people working together in the open.
JoeyLLM
Our flagship open language model project. JoeyLLM is coming soon, with a public chat interface planned so people can try it directly.

We have built public datasets totalling 1.3 trillion tokens across Australia, New Zealand, Canada, and the United Kingdom. Classifiers for regional language and country context are in development.

Southern Cross AI is a hands-on community of developers, researchers, students, and sponsors. Meetups are returning, and active contributors may be able to access GPU and compute resources for project work.

JoeyLLM is actively pretraining on our sovereign datasets. While pretraining finishes, we built this simulated chat console to preview its focus areas and capabilities.
Our model is built specifically to understand Australian vocabulary, policy guidelines, and local vocabularies—solving the problem of regional bias in standard foundational models.
