TL;DR
- Ground defense answers in approved internal content with RAG instead of model memory.
- Keep classified or controlled content inside VPC, on-prem or air-gapped deployments where policy requires it.
- Scope retrieval per team, client or site so permissions and confidentiality hold at query time.
- Keep a named human owner for every operational or program decision.
- Classification filters decide what the model can ever retrieve.
How it works, step by step
- Inventory the content to make searchable: technical manuals, logistics documentation, training material and program records.
- Define a data boundary for the pilot that excludes restricted material until controls are proven.
- Choose a deployment target: cloud for public content, VPC, on-prem or air-gapped for restricted data.
- Build an evaluation set with authorized subject-matter experts so answer quality is judged by domain experts.
- Ingest, chunk and embed approved documents, and require citations on every answer.
- Add refusal behavior for questions outside the indexed, approved content.
- Review logged interactions on a schedule and expand only after accuracy and access checks pass.

Where defense teams start
Start with internal questions that already have a written answer. High-value first workloads include:
- Technical manuals: answer from controlled maintenance and operator documentation.
- Logistics and sustainment: retrieve supply, transport and sustainment guidance.
- Training and doctrine: surface course material and doctrine summaries with citations.
- Program records: answer from program documentation inside classification boundaries.
Each use case augments staff with cited answers; none replaces authorized reviewer judgment.
A private RAG architecture for defense knowledge
The stack is consistent across industries: ingest approved technical manuals, logistics documentation, training material and program records, chunk and embed with a multilingual embedding model, store vectors inside your environment, and call chat completions that answer only from retrieved context. Plugsky embeddings and chat completions are OpenAI-compatible, so teams already using OpenAI SDKs change the base URL and keep their code.
Deploy air-gapped where required, keep vectors and logs on approved infrastructure, and enforce metadata filters for program and classification. Use strict refusal behavior for questions outside the indexed, authorized corpus.
Access control, confidentiality and audit
Classification boundaries decide everything: retrieval must never cross them, and the deployment must keep prompts, vectors and logs on approved infrastructure. Air-gapped options suit controlled environments. Treat all output as drafts for authorized review, and do not let generated text enter official records without approval.
The technical controls are consistent: enforce permission-aware retrieval in your own service layer, scope API keys per application, team or tenant, rotate keys, and retain request and response logs on a defined schedule. Regulatory obligations vary by jurisdiction and sector, so map them with counsel rather than assuming one framework covers every deployment; Plugsky supplies the deployment and logging primitives you document.
See air-gapped LLM deployment for related deployment and control detail.
Rollout and human oversight
Pilot on unclassified training material before touching classified or controlled content. Build a labelled question set with authorized subject-matter experts, then measure retrieval hit rate, citation correctness and answer accuracy before and after every index or model change. Require citations on every answer, refuse out-of-scope questions, and name a human owner for every operational or program decision.
Review logged interactions weekly at first, correct the index rather than the prompt when retrieval misses, and expand the corpus only when accuracy and access checks pass.

Frequently asked questions
Can defense organizations keep data private with Plugsky?
Yes. Choose the deployment boundary that matches the data: Plugsky cloud for public content, or your VPC, on-prem and air-gapped options for restricted material. Access is controlled with scoped API keys and usage analytics.
Do we need to fine-tune on our internal documents?
Not for a first release. Fine-tuning is coming soon and is better for style than facts. RAG keeps answers current, permission-aware and traceable to a source, which matters more for internal knowledge.
Which model should we use?
Start free with plugsky-micro and plugsky-lite to validate retrieval, then evaluate mid-tier and frontier models from the 30+ model catalogue on your own question set.
How do we stop wrong or unsupported answers?
Restrict the assistant to approved indexed content, require citations, refuse out-of-scope questions and keep a human decision-maker for every regulated or client-facing outcome.
How is pricing structured?
Self-serve plans are flat monthly with unlimited fair-use usage, and there are no per-token charges on self-serve plans. See the live pricing page for current plans and the free tier.
Can this run on classified networks?
Air-gapped deployment is designed for isolated environments. Confirm the specific requirements and accreditation path for your network with the Plugsky team and your security authority.
How are answers kept inside classification boundaries?
Apply classification metadata at ingestion and enforce filters before retrieval, so the model only ever sees content the requester is cleared to access.
