## Fine-Tuning an Open Model on Your Company’s Data for Wisconsin businesses

Fine-Tuning an Open Model on Your Company’s Data from Wisconsin Tech Shop: Teach an open model your terminology, writing style and tasks with LoRA fine-tuning on your own examples, then measure it against the base model so you know it actually got better. We work with businesses throughout Wisconsin, including Milwaukee, Madison, Green Bay, Appleton, Kenosha, Eau Claire, La Crosse, Wausau and the Northwoods. Pricing typically starts at $6,000, and most projects take 3–6 weeks.

### What's included

- A clear goal and a test set before any training
- Training examples cleaned and prepared from your work
- LoRA or QLoRA fine-tuning on your hardware or a private GPU
- Side-by-side scoring against the base model
- The trained model handed over and deployed

What this can look like

A Milwaukee insurance agency fine-tunes a model on years of approved letters, so first drafts come out in its tone, with its terms.

Illustrative example of a typical project.

## Who it's for

Law firms, clinics, accountants, manufacturers, engineering firms, schools and any company with files that shouldn’t leave the building, plus owners who would rather own their AI than rent it forever.

## How it works

1. **Free fit call:** What should the AI do, which data can it see and who will use it? We tell you honestly whether local, cloud or hybrid fits best, with rough costs for each.
2. **Sizing and pilot:** We size the hardware and models to your users and documents, then pilot on your real work so you see the quality before buying more.
3. **Build and lock down:** Hardware built and tested under load, models served behind company sign-in with permissions and logging, document search connected and staff trained.
4. **Own it, with backup:** Everything is documented and in your name. On an optional care plan we keep models, security patches and backups current.

## Fine-Tuning an Open Model on Your Company’s Data FAQs

### Do we need fine-tuning, or just document search?

Document search (RAG) usually comes first: it answers from your files and stays current as they change. Fine-tuning helps when the model must learn a style, a format or a specialized task. We tell you honestly which you need.

### How much data does it take?

Often a few hundred to a few thousand good examples. Quality matters more than quantity, and we help you gather and clean them.

### Is a private model as good as ChatGPT or Claude?

For drafting, summarizing, searching your documents and most everyday work, today’s open models are very capable. For the hardest reasoning the largest cloud models still lead, which is why many companies run a hybrid: sensitive work stays local and approved tasks can use a cloud model.

### What hardware does it take?

Anything from a recent computer with plenty of memory for one person, to a GPU workstation for a team, to a dedicated multi-GPU server for a whole company. We size it to your users, models and documents and quote it upfront.
