Private GPT
Private GPTYour own GPT — on your data, under your controls, hosted where you say.
Macsons builds Private GPT deployments for organisations that need enterprise LLM capability without their data leaving their tenancy. Cloud, on-prem, sovereign — you pick.
The problem we solve
Public LLMs are powerful but off-limits for sensitive data. A Private GPT — properly built — gives you the same capability inside your walls, with the auditability regulators and boards require.
Capabilities
What we deliver
Every capability is production-grade — designed to run in your environment, under your controls, against your KPIs.
Deployment topology
Azure OpenAI, AWS Bedrock, GCP Vertex, self-hosted open models — including air-gapped and sovereign posture.
Retrieval-augmented generation
Grounded, cited answers on your documents, wikis, tickets and databases.
Access & identity
SSO, role- and document-level access; users only see what they're entitled to.
Safety & guardrails
PII redaction, jailbreak defence, injection resistance and human-in-the-loop escalation.
Evaluation & governance
Model registry, evaluation suites, red-teaming and audit logs aligned to ISO/IEC 42001 principles.
