Local LLM
Building Local LLM Agents on Edge Servers
How to run a useful LLM agent entirely on-premise, so plant data never leaves the building.

Cloud LLM APIs are convenient, but in many industrial settings they’re a non-starter: data governance won’t allow operational data to leave the network. The good news is that a local LLM agent is now genuinely practical.
The minimal stack
A workable on-premise setup needs four pieces:
- A quantized open-weight model served locally (e.g., via an inference runtime).
- A retrieval layer over internal documents and operational data.
- An orchestration loop that lets the model call tools.
- Guardrails and logging for traceability.
# Pseudocode for a retrieval-augmented answer
context = retriever.search(query, top_k=5)
prompt = build_prompt(system, context, query)
answer = local_llm.generate(prompt)Why on-prem changes the design
When you can’t fall back to a giant cloud model, you lean harder on:
- Retrieval quality — a smaller model with great context beats a bigger model guessing.
- Narrow scope — an agent that does three things well is more valuable than one that does everything poorly.
- Determinism where it matters — for actions with side effects, prefer explicit tools over free-form generation.
The payoff: an internal copilot that answers questions about the plant without a single byte leaving the building.
