LLM fine-tuning
LLM fine-tuning — when prompt engineering isn't enough
If the base model doesn't understand your domain, brand voice, or specialised terminology, fine-tuning is the answer. UseAIEasily ships LLM fine-tuning from Budapest for Hungarian and international clients.
01
When to fine-tune
- Domain terminology the base model doesn't handle well
- Brand voice and tone that must stay consistent
- Structured output (JSON, XML) that must be exact every time
- Specialised domain (legal, medical, financial) where base models stay generic
- Cost: a fine-tuned smaller model is cheaper than GPT-4 + prompt engineering
02
What we deliver
Dataset prep
Collection, cleaning, labelling, augmentation, train/val/test split. Multilingual corpus handling.
Model selection
OpenAI (GPT-4o-mini, GPT-4.1), Anthropic (Claude context engineering), open-source (Llama 3.1, Mistral, Qwen) on Together or self-hosted vLLM.
Training and eval
LoRA or full fine-tune, hyperparameter tuning, eval suite based on real business metrics — not just loss.
Deployment
Managed or self-hosted vLLM in EU region. A/B test against base, monitoring.
03
Timeline and cost
PoC fine-tune: 3–4 weeks, €10k–€20k. Production fine-tune: 6–10 weeks, €25k–€60k (GPU compute separate).
