LLM Training

Custom and fine-tuned language models that know your domain, run on your terms, and keep your data yours. We handle the full cycle: data preparation, fine-tuning, evaluation, and deployment — on-premise or in your cloud.

Fact: we are ISO 27001 certified (TÜV Austria), so your training data stays exactly where it belongs.

Generic Models Don’t Know Your Business

  • Answers sound right but miss your products, prices, and rules
  • Your data can’t leave your infrastructure — most AI services demand that it does
  • Per-request API costs grow with every new user
  • Prompt tweaks stopped moving the needle long ago

We’ve seen this on project after project. When prompting hits its ceiling, training is the next step: a model tuned on your data answers better, runs cheaper per request, and keeps your knowledge yours.

Dataset Preparation

Good models start with good data. We turn what you already have into clean, structured training datasets.

  • Documents, tickets, chats, and code as source material
  • Cleaning, deduplication, and labeling
  • Privacy filtering before anything reaches training

Fine-Tuning and Evaluation

We adapt open-weight models to your domain and prove the gain before you deploy.

  • Fine-tuning for your tasks, tone, and terminology
  • Benchmarks built from your real cases
  • Side-by-side evaluation: base model vs your model

Deployment on Your Terms

The trained model doesn’t arrive as a file. We integrate it into your product and operations — wherever it needs to run.

  • Your infrastructure, private cloud, or hosted by us
  • Integration into existing products and workflows
  • Support after release

Continuous Improvement

Your data grows — your model should keep up.

  • Retraining as new data arrives
  • Monitoring for drift and quality
  • Versioning and rollback
