Canberra, Australia, 10 November 2026 – Trellis Data today announced the launch of Agentaus 1, its next-generation sovereign AI model, marking a major step forward in Australia’s ability to develop advanced artificial intelligence capability in Australia.
At 220 billion parameters, Agentaus 1 is around 50 per cent larger than Trellis Data’s previous model and meets leading global benchmarks with a world ranking of 43 for foundational AI models. It has been designed to deliver greater accuracy, deeper multi-step reasoning and longer, more coherent outputs, while remaining efficient enough to operate at scale on smaller compute clusters.
The model provides Australian businesses and government with access to locally developed AI that combines fast performance with security, sovereign data protection and transparent consumption. Its end-to-end approach is designed to help customers solve their challenges directly and efficiently, reducing the need to access multiple AI models for different tasks.
Trellis Data has been building applied AI capability in Australia for a decade, including for high-security environments. Agentaus 1 builds on that foundation and reflects the company’s ambition to establish Australia as a producer of advanced AI, rather than relying exclusively on technology developed overseas.
Trellis Data founder Michael Gately said Agentaus 1 demonstrates that world-class AI models can be developed in Australia: “Agentaus 1 puts Australia on the global stage as an LLM AI model producer. It’s the next generation of Trellis Data’s sovereign AI capability, giving Australian organisations a more effective, faster and cost-efficient model while keeping their data and investment here in Australia.
“We’re already working on what comes next. Our ambition is to keep building world-class AI here at home and demonstrate that Australia can be a producer of advanced AI, not simply a consumer of technology built elsewhere.”
Agentaus 1 has been developed with practical adoption in mind. The model gives organisations access to more capable AI while maintaining the speed, security and cost-effectiveness required for real-world use. Customers can also access Trellis Data’s Canberra-based team for support from local people with deep AI adoption and implementation expertise.
The launch comes as Australian businesses and government increasingly consider how to capture the productivity benefits of AI while maintaining control over sensitive data, spiralling technology costs and critical national capability.
Trellis Data sees the opportunity beginning at home: building trusted AI for Australian businesses, communities and government, before taking Australian AI expertise into international markets over time.
Agentaus 1 is now available to both individual users and businesses via free, subscription, enterprise and API tiers at agentaus.com.au.
