# Fine-tuning & Model Customization

Smaller, faster, cheaper models that know your domain.

[Discuss Fine-tuning](https://aibyos.com/contact)

When prompting isn’t enough, we fine-tune. We build training datasets, run supervised fine-tuning, LoRA/QLoRA and preference tuning (DPO), and distil large-model behaviour into small open models you can host yourself, always benchmarked against the prompted baseline.

## Typical use cases

### Distil to a small, private model

**Challenge.** A large hosted model works but is too slow, costly or can’t see sensitive data.

**What we build.** Distillation into a fine-tuned 3–14B open model running in your own cloud, matched to the original on your evals.

### Domain-language model

**Challenge.** General models misread your terminology, codes or languages.

**What we build.** Fine-tuning on curated domain data (e.g. Polish legal text, medical coding, internal jargon) with measurable accuracy gains.

### Classification & routing at scale

**Challenge.** Millions of messages need labelling; LLM calls per item are too expensive.

**What we build.** A fine-tuned compact classifier or embedding model delivering LLM-level quality at a fraction of the cost.
