Custom LLM application development: Custom LLM Applications

Applications built on large language models and grounded in your own knowledge, so answers are accurate, cited and visible only to the people who should see them.

Definition

What is a custom LLM application?

A custom LLM application is software built on a large language model and connected to your organisation's own data. Using retrieval-augmented generation (RAG), it finds the relevant passages in your documents, answers from them and cites its sources, so answers stay accurate and visible only to people with access.

Service

What we deliver

  • Knowledge assistants over documents, wikis and shared drives
  • Retrieval-augmented generation (RAG) with source citations
  • Copilots embedded in your internal tools and workflows
  • Role-based access control and data isolation
  • Evaluation suites that measure accuracy before and after launch

A good fit if

Your organisation's knowledge is scattered across PDFs, folders and people's heads.

Process

How we build a custom LLM application

01

Define the questions

We gather the real questions people need answered and agree what a correct answer looks like.

02

Prepare your knowledge

Documents, wikis and drives are cleaned, split and indexed, with permissions carried over from the source.

03

Build retrieval and answers

The application finds the relevant passages, answers from them and shows the sources it used.

04

Measure accuracy

An evaluation suite built from your questions scores the system before launch and after every change.

Illustrative example

What it could look like.

Imagine a manufacturer whose service engineers search through hundreds of PDF manuals. A knowledge assistant lets them ask in plain language, returns the procedure with a link to the exact page, and only shows documents each engineer's role allows.

Where to start

Your first project, and when to skip it.

A good first project is an internal assistant over one well-kept document set, such as HR policies or product manuals. Most first projects begin as a proof of concept lasting two to four weeks. See ways to work with us

If your source documents are out of date or contradict each other, fix those first, since the assistant can only be as accurate as what it reads. For a small set of documents, good search may be enough.

FAQ

Custom LLM Applications, explained.

Have a question we haven't covered?

Talk to us
What is retrieval-augmented generation (RAG)?

RAG lets a language model answer from your own documents. The system first finds the relevant passages, then generates an answer grounded in them and cites the sources.

Will our data be used to train public models?

No. We configure model providers so your data is not used for training, and we can deploy privately or on-premise when your data must stay in-house.

How do you know the answers are accurate?

We build evaluation suites from your real questions and measure accuracy before launch and after every change.
