Model Fine-tuning & Datasets

LLM Fine-Tuning & AI Dataset Preparation

Fine-tuning teaches a language model your terminology, formats and judgement, so it answers in your style with fewer instructions and at lower cost. We prepare the training data, fine-tune the model and prove the improvement with evaluations.

  • Your data stays yours
  • Accuracy tested before go-live
  • Works with your CRM, ERP & WhatsApp

What this covers

  • AI Model Fine-tuning
  • AI Dataset Preparation

Typical timeline

Proof of concept in 3–4 weeks; production rollout typically 6–12 weeks.

Who it is for

Who our LLM Fine-Tuning service is for

Fine-tuning is not always the answer, so we first test whether prompting or RAG is enough. When it is worth it, we curate high-quality examples, use efficient techniques such as LoRA, and compare the tuned model against the baseline on your own test set.

Discuss your requirement
  • 01

    Companies needing consistent output formats such as reports, notes or classifications

  • 02

    Teams wanting a smaller, cheaper model that matches large-model quality on a narrow task

  • 03

    Organisations that must run models privately on their own infrastructure

  • 04

    Businesses with specialised legal, medical, financial or technical language

Capabilities

What is included in LLM Fine-Tuning

Fine-tuning feasibility study

Baseline tests with prompting and RAG confirm that fine-tuning will beat them before you spend on it.

AI dataset preparation

Collection, de-duplication, anonymisation and formatting of training examples from your records.

Data labelling & quality control

Guidelines, labelling workflows and reviewer agreement checks for reliable training data.

Parameter-efficient fine-tuning

LoRA and QLoRA tuning of Llama, Mistral, Qwen or Gemma, and hosted fine-tuning where suitable.

Evaluation & benchmarking

Task-specific test sets and side-by-side comparisons of accuracy, format adherence and cost.

Private deployment

Tuned models served on your cloud or on-premise GPUs behind an OpenAI-compatible API.

How we work

A clear, step-by-step delivery process

You always know what happens next, who is responsible and what you will receive at each stage.

Typical timeline

Proof of concept in 3–4 weeks; production rollout typically 6–12 weeks.

  1. 01

    Baseline

    Current model performance is measured on your real tasks.

  2. 02

    Dataset design

    Examples, labels and quality rules are defined and collected.

  3. 03

    Training runs

    Models are fine-tuned with tracked experiments.

  4. 04

    Evaluation

    Tuned and baseline models are compared on held-out data.

  5. 05

    Deployment

    The winning model is served, monitored and documented.

Deliverables

We recommend tools based on your scale, budget and existing systems, not on what is fashionable. Every choice is explained in the proposal.

Engagement models

Choose how we work together

Proof of concept

A 3–4 week pilot on your own data with agreed accuracy targets, so you see real results before scaling.

Most chosen

Production build

Hardened integration, guardrails, monitoring and admin controls, delivered in milestones with a fixed quote.

Managed AI operations

Ongoing prompt and model tuning, evaluation runs, cost monitoring and feature additions on a monthly plan.

How pricing works: AI projects are priced in two stages: a fixed-price proof of concept, then a production quote based on what the pilot proves. Model and API usage costs are estimated upfront and billed at actuals.

FAQs

LLM Fine-Tuning: frequently asked questions

When should we fine-tune instead of using prompts or RAG?

Fine-tune when you need a consistent style or format, a narrow task done cheaply at high volume, or a small model that runs privately. If the goal is answering from changing documents, RAG is usually better. We test both before recommending.

How many training examples are needed?

For many format and style tasks, a few hundred to a few thousand high-quality examples are enough with LoRA-style tuning. Quality matters more than quantity, which is why dataset preparation is a large part of the work.

Can you remove personal data from our training set?

Yes. We anonymise or pseudonymise personal data during dataset preparation and document the process, in line with the data minimisation principles of the DPDP Act.

Where will the fine-tuned model run?

Either on a managed provider or on GPUs in your own cloud account or data centre. Open-source models can be fully owned and hosted by you.
