Your own environment
An open model with a LoRA adapter runs on your infrastructure, so data never leaves the company perimeter.

Fine-tuning models for company needs
Learn when fine-tuning and LoRA add value beyond prompts and RAG, how to prepare datasets and measure model quality before and after deployment.

How we choose the method: prompt -> RAG -> fine-tuning
Use the cheaper method first, and fine-tune only when its limits are proven

When fine-tuning is justified, and when it is not
When it is justified
- The model should speak in your domain's terminology and style: legal phrasing, technical regulations, industry jargon.
- Classification, extraction, and labeling on your data, where prompts and RAG consistently fail to reach the required accuracy.
- You need a stable response format for integration: the model must answer strictly by schema, not however it turns out.
- The model runs locally in a closed environment, and it is important to squeeze quality out of a compact open model.
When it is not needed
- Knowledge changes every week, so fresh facts are a RAG task, not a model weights task.
- If there are too few real examples, fine-tuning on dozens of input-to-answer pairs will not measurably improve quality.
- The task can be solved with a prompt or a few in-context examples, so the cheaper method has not been exhausted yet.
- If you need a universal chat without a measurable quality metric, there is no basis for defining an acceptance criterion.

What we do: datasets, LoRA adapters, metrics
-
01
Process breakdown and evals
We define the task and build a validation set of real examples. We measure the baseline quality of the prompt and RAG, which becomes the starting point.
-
02
dataset from operational data
We collect and clean input-to-reference-answer pairs from documents, conversations, and business systems. Personal data is anonymized before being passed to the model.
-
03
LoRA fine-tuning for an open model
Adapters instead of full fine-tuning: faster and cheaper, the process is reproducible, and the dataset and weights remain the company's property.
-
04
Measure before and after
The same metric on the same validation set. Improvement on evals is the acceptance criterion, not a subjective "it looks better."
-
05
Production handoff
The model is deployed in your environment, and your team gets a process for updating the dataset and retraining it again - without depending on us.
Where the model lives: your environment and Federal Law 152
LLM gateway for GDPR
If part of the traffic goes to external models, LLM gateway anonymizes personal data before it reaches the model and returns the real values in the response.
RAG alongside, not instead
Fine-tuning handles style, format, and domain skills; fresh facts are retrieved by RAG knowledge base with a source link.

One process - one price - payment after delivery
Fine-tuning is also an AI implementation process: we define the acceptance criterion before launch as quality metrics on a validation set, and payment is due after the process is accepted. See the pricing reference on the page pricing and payment models; calculate the economics for your volumes in AI implementation calculator.
- Acceptance criterion defined before launch
- Payment after acceptance
- The dataset and weights are yours
