What is LLM Fine-Tuning?

LLM fine-tuning takes a pre-trained language model - GPT, Llama, Mistral, or similar - and trains it further on your company's data. The result is an AI that performs like it was built for your industry from the start, using your terminology, following your processes, and producing outputs in your style.

Benefits

Make your AI feel native to your business: faster, more accurate, and a true competitive advantage from day one.

AI that understands your industry terminology from day one

Faster, more accurate responses without complex prompt engineering

Competitive advantage through proprietary AI capabilities

Why It Matters

Generic AI models hallucinate on domain-specific tasks. They don't know your underwriting guidelines, your clinical protocols, or your compliance rules. A fine-tuned model trained on your data gives accurate, consistent answers using your terminology - without the endless prompt engineering workarounds that generic models require.

What You Get

A custom AI model trained specifically on your proprietary data
Measurable accuracy improvements on your domain-specific tasks
Lower per-query costs compared to prompting oversized generic models
Full ownership of the model - deploy it where you want, use it how you want

How We Deliver

We start by evaluating your data and defining what success looks like - accuracy targets, latency requirements, deployment constraints. Then we prepare your training data, fine-tune the selected base model, and run rigorous evaluations against your benchmarks. Once the model meets your standards, we deploy it to production with monitoring and A/B testing against the baseline.

Our Process

1

Assess

1 week

Evaluate your data, define success metrics, choose the right base model.

2

Build

2–4 weeks

Prepare training data, fine-tune the model, run initial evaluations.

3

Deploy

1–2 weeks

Production deployment with monitoring, A/B testing against baseline.

Use Cases

Healthcare

Medical Documentation

Fine-tuned model that generates clinical notes using correct medical terminology and formatting.

Insurance

Underwriting Automation

Model trained on underwriting guidelines to assess risk and recommend coverage terms.

Financial Services

Regulatory Compliance

AI that understands and applies your specific compliance rules to document review.

Frequently Asked Questions

Common questions about LLM Fine-Tuning.

It depends on the task. Simple classification can work with hundreds of examples. Complex generation tasks benefit from thousands. We assess your data and recommend the right approach.

We work with open-source models (Llama, Mistral, Phi) and commercial APIs (OpenAI, Anthropic) depending on your deployment requirements and data privacy needs.

Typically 2-4 weeks from data preparation to initial model. Production deployment adds another 1-2 weeks for testing and monitoring setup.

Yes. Fine-tuned open-source models can run entirely in your private cloud or on-premises infrastructure.
