LLM Fine Tuning

End-to-end LLM customisation , from data preparation and supervised fine-tuning through to RLHF, evaluation and sovereign deployment.

What we do

How we approach this practice

We take open-weight foundation models and turn them into specialised, sovereign models tuned to your domain, your language and your policies.

We handle the full pipeline: corpus curation, supervised fine-tuning, LoRA / QLoRA / full-parameter approaches, instruction tuning and RLHF / DPO alignment.

Your data never leaves your environment. The resulting model is yours , deployed inside your perimeter, with no dependency on third-party APIs.

Scope

What we deliver

  • Supervised fine-tuning, LoRA / QLoRA and full-parameter approaches
  • Instruction tuning and RLHF / DPO alignment
  • Rigorous evaluation against domain benchmarks
  • Sovereign deployment , your data never leaves your perimeter
  • Continuous improvement pipelines
Engagement process

How an engagement unfolds

A repeatable process refined over 17 years of mission-critical delivery , adapted to the specifics of this practice.

  1. Step 01

    Define target

    Use-cases, acceptance criteria, evaluation benchmarks and policy constraints.

  2. Step 02

    Curate data

    Source, clean, de-duplicate and license-clear your training corpus.

  3. Step 03

    Choose method

    Select base model and tuning approach (LoRA, QLoRA, full FT, instruction, RLHF).

  4. Step 04

    Fine-tune

    Multi-stage training with checkpoints, ablation and alignment passes.

  5. Step 05

    Evaluate

    Domain benchmarks, red-teaming, bias and safety assessment.

  6. Step 06

    Deploy

    Sovereign serving stack with monitoring and continuous improvement.

Success story
