AI Services / Model Customization

Fine-tuned LLMs that match your voice — and your bar

We design, fine-tune, and operate custom LLMs tailored to your domain, voice, and acceptance criteria. From lightweight adapters to full fine-tunes, with eval suites, versioned datasets, and rollback safety — so fine-tuning becomes a disciplined engineering practice, not a one-off experiment.

Why Empiryx

Why our fine-tuning actually moves the needle

Dataset engineering as a first-class discipline — not 'gather your CSV'
LoRA / QLoRA / full SFT picked per budget, quality bar, and latency target
Per-task eval suites with golden sets so you can prove the lift, not vibe it
Versioned datasets and model artifacts — every fine-tune is reproducible
Rollback safety: A/B routing against the base model so a bad run can't ship
Private deployment options — your data, your weights, your VPC

Expertise

What we build

01

Domain specialization

Models that speak your domain — legal, medical, financial, technical — without leaking into generic prose.

02

Style & voice tuning

On-brand copy, replies, and content generation tuned to accepted examples.

03

Task compression

Smaller, cheaper models that hit your quality bar — instead of paying GPT-4 for every call.

04

Custom embeddings

Fine-tuned retrievers and embedders tuned to your corpus and vocabulary.

Expertise

Roles & capabilities we specialise in

A deeper look at the specialists we place and the work they ship.

Dataset curation

Synthetic + real data pipelines with dedup, quality filters, and labeler review.

Parameter-efficient tuning

LoRA, QLoRA, and adapter stacks for fast, cheap experiments and rollbacks.

Full SFT & DPO

Full supervised fine-tuning and preference alignment for higher-stakes lifts.

Eval harnesses

Per-task metrics with golden sets, LLM-as-judge, and human review loops.

Inference & serving

vLLM, TGI, or managed endpoints — picked for throughput, cost, and warm-start behavior.

Safety alignment

Jailbreak testing and red-team passes before any tuned model goes to users.

Process

How it works

01

Dataset engineering

We curate, dedupe, and label data from your domain, with quality filters and reviewer passes.

02

Fine-tune + eval

We run tuning (LoRA, QLoRA, or full SFT) against your golden eval suite and report the lift.

03

A/B & rollback

We deploy behind routing with automatic rollback to base on any regression.

04

Operate & retrain

We monitor quality in production and retrain against drift over time.

Get started

Customize the model — without losing control

Bring the data. We'll bring the dataset engineering, the evals, and the rollback safety.
