The Australian Platform for High-Performance, Sovereign AI
SouthernCrossAI is Australia’s sovereign foundation model infrastructure and AI services platform—built for enterprise, government, and AI builders who demand data control, low-latency performance, and regulatory alignment.
Onshore Inference & Training
All models and data hosted entirely within Australia.
Security Aligned Infrastructure
Built to align with APRA CPS 234 and privacy principles.
Predictable Token Economics
Transparent pricing across open-source and fine-tuned models.
Ultra-Low Latency
≤100ms response times for real-time enterprise workloads.
How SCX Handles LLM Workloads — Securely, Transparently
Input
A user prompt—chat message, document, or API call—is securely received within Australia.
Vaulted Context
If needed, SCX queries an encrypted, tenant-specific data vault to enrich the prompt with private or historical knowledge (e.g., RAG, legal Q&A).
Model Inference
The combined input is passed to a fine-tuned large language model hosted entirely on sovereign SCX infrastructure.
Output
The model returns a response in ≤100 ms (average), enabling real-time copilots or batch processing.
Token Metering
Input and output token counts are logged to your secure usage dashboard for billing, audit, and analytics—no overage surprises.
