Trellis Data launched Agentaus 1, a sovereign AI model with 220 billion parameters. The Australian company says the model is about 50% larger than its predecessor. The company also ranks it 43rd among foundational AI models globally.


Pricing and availability

Agentaus 1 is available at agentaus.com.au. Users can choose from free, subscription, enterprise, and API tiers. The model also runs on smaller compute clusters, which keeps operating costs down.

Company experience

Trellis Data was founded in Canberra in 2016. It has spent a decade building applied AI, including work in high-security government and defense settings. Investors include Main Sequence, a venture firm founded by CSIRO.

Sensitive document workflows

The model is designed for sensitive business and government documents. Public servants can turn policy submissions into ministerial briefs with references to originals. Australian data centers handle the documents, and customer material is not used for training.


Trellis Data says its products already meet proposed federal safety standards for frontier AI. The company plans to continue building advanced AI in Australia. It also plans to take Australian AI expertise into international markets over time.
