Private LLM options in Australia

“Private LLM” means different things to vendors: API with zero retention, VPC-hosted models, on-prem weights, or simply a private RAG layer over a public model. Australian buyers usually care about where prompts and documents live, who can see them, and whether residency promises match the architecture.

This is a buyer orientation guide — not a product catalogue. For builds, see AI software development → and integrations →.

Options buyers actually compare

  • Managed API with controls — strong models, contractual retention and region choices; still a third-party processor.
  • VPC / private endpoint — model traffic stays in your cloud tenancy; ops and cost shift to you.
  • Self-hosted / dedicated weights — maximum control; higher ops burden and capability trade-offs.
  • Private data path, shared model — retrieval and permissions in your estate; generation via an approved API — common for RAG assistants →.

Residency questions worth asking

  • Where are prompts, embeddings and logs stored — and for how long?
  • Are subprocessors and training-use policies acceptable for your data classes?
  • Do agency and customer contracts require AU-only processing, or is encrypted transit to an approved region enough?
  • Who holds keys, and can your team revoke access cleanly?

Legal and security teams should own the policy; we help map architecture to that policy without pretending every use case needs on-prem GPUs.

When “private” is overkill — and when it is not

Public FAQ content and non-sensitive ops copy rarely justify heavy private stacks. Customer PII, regulated records, M&A materials and unpublished IP often do — at least for retrieval stores and logging, even if generation uses a controlled API.

Pair residency choices with product shape: agents that write to CRM need permission design as much as model placement. See agent vs chatbot → and Audit → if the map is unclear.

Pitfalls

  • Buying “private” branding without reading retention and training clauses.
  • Ignoring embeddings and backup locations while focusing only on the chat UI region.
  • Skipping human oversight because the model is “inside the firewall”.

Need residency mapped to a real build?

Bring your data classes and constraints. We will recommend a model and hosting shape that matches risk — then integrate it with your tools.
