Twarx Solutions / Custom SLM

A model that’s an expert, not a generalist.

We design, train, and deploy custom Small Language Models — and private SLM + RAG systems — that run on your own infrastructure. Smaller, faster, cheaper, and more accurate than a general LLM for the work that actually matters to your business.

The basics

What is a Small Language Model?

A Small Language Model (SLM) is a compact AI model — typically a few hundred million to a few billion parameters — trained or fine-tuned for a specific domain or task rather than to know a little about everything.

Where a frontier LLM is a giant generalist that’s expensive to run and sends your data to someone else’s servers, an SLM is a focused specialist. Because it only needs to be brilliant at your work, it can be small enough to run on your own hardware — and still beat a general model on the tasks it was built for.

Why a custom SLM

The benefits, plainly

Smaller isn’t a compromise — for the right job, it’s the advantage.

Dramatically cheaper to run

A specialised SLM is a fraction of the size of a general LLM, so each query costs a fraction as much. For high-volume workloads that gap compounds into enormous savings month after month.

Faster, lower latency

Fewer parameters mean quicker responses — often real-time. Your users get instant answers and your pipelines process far more throughput on the same hardware.

Your data stays private

The model runs on your own infrastructure. Sensitive documents and customer data never leave the building or get sent to a third-party API — critical for regulated industries.

Beats general models in your niche

Trained on your category and your data, an SLM consistently outperforms general-purpose LLMs on the specific tasks it was built for — because it’s an expert, not a generalist.

You own it

You keep the weights, the training data, and the system. No per-token bills, no vendor lock-in, no risk of an API being deprecated or repriced out from under you.

Runs anywhere — even offline

Small enough to deploy on-prem, at the edge, or on a single GPU. It keeps working without an internet connection and without depending on anyone else’s uptime.

SLM + RAG

Give your model your knowledge — without retraining

RAG — Retrieval-Augmented Generation — connects your SLM to a private library of your own documents. Instead of relying only on what it learned in training, the model retrieves the most relevant passages from your data at question time and answers grounded in them.

Always up to date — add a document, it’s instantly usable
Answers cite their sources, so you can trust and verify them
Far less hallucination — it quotes your data, not its guesses
Your knowledge base stays private on your own infrastructure
01

Ingest

Your documents, manuals, and records are loaded and chunked.

02

Embed & store

Each chunk is embedded into a private vector database you control.

03

Retrieve

At question time, the most relevant passages are pulled instantly.

04

Answer

Your SLM responds grounded in those sources — with citations, not guesses.

Where it shines

Use cases

Anywhere you have a focused task, sensitive data, or high volume, a custom SLM tends to win.

Customer support over your docs

An assistant that answers from your real product manuals, policies, and FAQs — accurately, instantly, and in your brand’s voice.

Internal knowledge assistant

Let your team ask plain-language questions and get grounded answers from your wiki, SOPs, and historical records — no more hunting through folders.

Document extraction & classification

Read, tag, and structure invoices, contracts, and forms at scale — turning piles of unstructured paperwork into clean, usable data.

Regulated-domain copilots

Legal, medical, and financial assistants that stay on-prem for compliance while delivering expert-level help grounded in your own approved sources.

On-device & edge AI

Embed intelligence directly into apps, devices, or kiosks that must work fast, offline, and without sending data to the cloud.

Domain-specific automation

Classification, routing, summarisation, and decisioning tuned to your category — cheaper and more accurate than wiring up a giant general model.

How we build it

From your data to a model you own

01

Scope

We define the task, success metrics, and whether an SLM is genuinely the right tool.

02

Data

We curate, clean, and label your domain data — the real source of an SLM’s edge.

03

Train

We fine-tune and instruction-tune the model for your category and tasks.

04

Evaluate

We test against real-world cases with an evaluation suite you can trust.

05

Deploy

We ship it to your infrastructure, document it, and train your team to own it.
