Practical local LLM infrastructure design

Build a local LLM setup that fits your work

Plan a local LLM setup around your workload and data. We recommend hardware, model serving and operating safeguards before you build.

Local LLM basics: why run it on your own machine, and what to decide first

An introduction to local LLMs, access boundaries, hardware and model choices, and the first steps to try one. Automatic English and Korean translations are available on note.

Offer

Choose a local LLM setup before buying hardware.

Review the workload, choose suitable hardware, and define the model-serving and operating plan.

Local workload and data path
We map the target local use case, data location and rough volume, privacy constraints, expected users, latency, and current environment.
Machine and GPU sizing
We size GPU, VRAM, RAM, storage, power, thermals, and uptime around the workload and the machine you have or may buy.
Local serving and operations
You receive a practical model/runtime, secure access, storage, monitoring, handover, and first implementation plan. Cloud or hybrid appears only as a fallback note if needed.
Process

How the Local LLM Infrastructure Audit works

A 45-minute discovery call, followed by a written plan. Scope, price and delivery date are agreed before work begins.

A short intake covers four local-design prompts: target workload/use case, current machine/GPU/environment, data location/types/rough volume plus privacy/access/retention constraints, and expected users/concurrency/latency/outcome. Identity and contact fields are separate; share what you know. The audit call itself uses 12 core questions, with up to 3 extra follow-ups only when needed.

01
Understand the local workload and data
We map the target local use case, data location and rough volume, privacy/access/retention constraints, expected users, concurrency, latency, and current environment.
02
Size the local machine
We turn the workload into GPU, VRAM, RAM, storage, power, thermals, and uptime requirements for an existing machine or a practical BOM.
03
Plan local serving and operations
We outline the model/runtime, secure remote access, storage, monitoring, handover, TCO assumptions, and a small implementation plan. If local is unsuitable, we add only a brief fallback note.
Deliverables and suitable workloads
Deliverables

What you walk away with

A practical local LLM setup decision and a clear first implementation step, not a large build commitment.

✓Local workload and data constraints, including location, rough volume, privacy/access/retention, users, latency, and the current environment
✓Local LLM machine recommendation with explicit sizing assumptions, costs, trade-offs, and operating constraints
✓Hardware BOM or existing-machine plan covering GPU, VRAM, RAM, storage, and power
✓Model/runtime, secure remote access, storage, monitoring, and handover plan
✓TCO assumptions, a small implementation plan, and a brief cloud/hybrid fallback note only if local is unsuitable
Good fit

Who this is for

Best for teams that need a grounded local LLM decision before they buy hardware or expose sensitive data. It also makes clear when local is not a fit.

•Solo founders and small teams exploring local LLM inference for a real workload
•Operators with an existing machine or GPU who need a safe local serving and access plan
•Data-sensitive teams that need a local data path and machine plan before implementation
•Teams that want explicit trade-offs instead of guaranteed savings or performance claims
Audit sample

What the Local LLM Infrastructure Audit report actually looks like

The output is a decision-ready local LLM memo: constraints, machine sizing, runtime plan, operating safeguards, and a small next step.

Memo structure

A decision-ready local LLM plan

The report turns workload evidence into a practical local setup route.

•1. Executive Summary — The local workload reviewed, data boundary, machine recommendation, key trade-offs, and the first validation step.
•2. Local Workload and Data Constraints — Users, concurrency, latency, data location and rough volume, privacy/access/retention, current hardware, and operational ownership.
•3. Local Machine and Runtime Plan — A hardware BOM or existing-machine plan for GPU, VRAM, RAM, storage, power, model runtime, and upgrade boundaries.
•4. Local Serving and Security Plan — Model serving, secure remote access, storage, monitoring, handover, and explicit operating assumptions.
•5. Implementation and Fallback Note — A small implementation plan with the next validation step; if local is unsuitable, a brief cloud or hybrid fallback note without full alternative architecture.
Example workloads

From workload to a local operating route

Recommendations keep data boundaries, machine trade-offs, and human approval visible.

•Private research assistant — Founder / analyst: Sensitive notes need local summarization without an undefined data path → Define the local data boundary, machine fit, serving runtime, and human review
•Internal document search — Operations team: A shared machine exists, but GPU headroom, remote access, and retention are unclear → Existing-machine assessment + serving runtime + secure access and monitoring plan
•Team knowledge workflow — Ops / leadership: Private records need a deliberate local model path and access boundary → Local serving plan with client-controlled records, model routing, and approval gates

Final recommendations are ranked by local workload fit, implementation effort, operating risk, and total-cost assumptions. If local is not suitable, the report says so and adds only a brief fallback note.

Typical use cases

Where the audit tends to help first

Common entry points for a grounded local LLM decision.

•Local LLM inference for research and internal operations
•Existing GPU or workstation assessment before a model-serving build
•Local data-boundary, sizing, and TCO planning
•Secure remote access, storage, monitoring, and handover planning
•Workflow and knowledge systems that depend on a deliberate local model route
Commercial logic

Simple local LLM service economics

The audit produces a written infrastructure plan. Implementation is a separate engagement; scope, price and delivery date are confirmed in your quote.

That keeps the entry point light and gives implementation a measured starting point: validate local fit, then build only what the evidence supports.

What Oxtane can design and build after the audit

Infrastructure comes first. Where the audit supports implementation, we can extend the plan into model serving, secure operations, and the workflow systems that depend on it.

GPU & machine architecture
Planning GPU selection, VRAM headroom, RAM, storage, power, thermals, and uptime around the workload and the constraints of the existing machine or proposed BOM.
Local inference & model serving
Designing a model/runtime path for local inference, with explicit scope for supported models, capacity, upgrades, fallback options, and operator handover.
Secure remote access, storage & monitoring
Designing access boundaries, encrypted storage, backup or retention choices, health checks, logs, and monitoring so a private system can be operated deliberately.
Workflow and database infrastructure — separately scoped after the audit
Separately scoped implementation work after the audit: PostgreSQL/Supabase schema and data modeling, migrations/ingestion/idempotency, RLS/access, indexes/performance, backup/retention/observability, resolver/API contracts, and operational handover. pgvector or retrieval/RAG is considered where appropriate. This database implementation work is not included in the planning audit; workflow and knowledge systems remain separately scoped as needed.
AI routing & cost controls — QuorumRouter
Designing capability- and budget-aware model routing with structured validation, safe fallbacks, circuit breakers, and failure telemetry — without claiming guaranteed token savings.
Safe agent operations — SafeLoop
Adding checkpoints, tamper-evident artifacts, approval gates, and covered local-file recovery. External actions require separate compensation or operator handling.
Role-separated agents & evaluation
Retaining planner, specialist, reviewer, red-team, and evaluation workflows with explicit context, supported actions, deterministic tests, and evidence-based iteration.
Research & operations automation
Turning recurring research, reporting, synthesis, approvals, and internal handoffs into consistent human-in-the-loop workflows after the infrastructure is ready.
Operator experience under sustained GPU load
Prior mining/GPU experience includes building and operating GPU systems under sustained load, with practical attention to power, thermals, hardware selection, and uptime.
