Train AI Models on Your Own Data

Off-the-shelf models miss your products, documents, defects or language, and sending sensitive data to third-party APIs is not always an option.

A model trained or fine-tuned on your data — with a clean dataset, accuracy measured on your own test set, and a production deployment you fully own.

Typical timeline: 3-8 Weeks.

Capabilities

  • Dataset collection, cleaning & labelling
  • LLM fine-tuning (LoRA / QLoRA) on your domain data
  • Custom vision models: detection, classification, segmentation
  • Face, OCR and speech model fine-tuning
  • Evaluation on your own test set & model comparison
  • Quantisation and deployment to cloud, on-premise or edge

What you receive

  • Curated & Versioned Training Dataset
  • Trained Model Weights You Own
  • Evaluation Report on Your Test Set
  • Inference API & Deployment Scripts

Technology

PyTorch · Hugging Face Transformers · LoRA / QLoRA · YOLOv8 · Weights & Biases · ONNX · TensorRT · vLLM

Frequently asked questions

When should we train or fine-tune our own model instead of using ChatGPT or another API?
When the task depends on knowledge or patterns general models do not have (your products, defects, documents, language or tone), when data must stay private, or when per-request API costs get too high at your volume. Often retrieval (RAG) is enough — we tell you which approach fits before you spend anything on training.
How much data do we need?
It depends on the task. Fine-tuning a language model can start from a few hundred to a few thousand good examples; a custom vision model usually needs a few hundred labelled images per class. We assess your data during scoping and can help collect and label more.
Who owns the trained model?
You do. Model weights, training code, dataset versions and evaluation results are handed over in full — no lock-in.
Can the model run on our own servers?
Yes. We deploy to your cloud account, to on-premise GPU servers, or quantised for edge devices, behind an API your systems call.
