Training & Fine-tuning

Fine-tuning is specialising a pre-trained AI model on your data. Instead of starting from scratch, you start from a model that already “speaks” and teach it your domain.

With techniques like LoRA and QLoRA, fine-tuning is efficient even on modest hardware.

Concrete cases

01

Corporate LLM Fine-tuning

A language model specialised in your domain: terminology, communication style, policies and best practices.

02

Custom Classifier

Model trained to classify your data: review sentiment, product categories, ticket priority, request intent.

03

Domain NER

Recognition of entities specific to your sector: product codes, regulations, technical terminology.

How we work

From idea to production

  1. Dataset preparation

    Collection, cleaning, labelling and splitting of training/validation/test data.

  2. Architecture selection

    Choosing the base model and strategy: full fine-tuning, LoRA, QLoRA or adapter layers.

  3. Training and validation

    Training with early stopping, validation on business-relevant metrics.

  4. Deploy and versioning

    Model in production with versioning, A/B testing and automatic retraining pipeline.
