FAQ
What data do I need to provide?
You need input-output example pairs relevant to your task (e.g., customer question + ideal answer). Minimum 50–100 examples works for basic tasks; 1,000+ examples gives the best results. I can also generate synthetic training data if needed.
Which models do you fine-tune?
OpenAI models (GPT-3.5-turbo, GPT-4o-mini), Meta LLaMA 3, Mistral 7B/8x7B, Falcon, Phi-3, Gemma, and other open-source models — via HuggingFace or direct training.
What if my data is messy or unformatted?
No problem! Standard and Premium packages include full dataset preparation — cleaning, deduplication, formatting, and JSONL conversion. I handle everything.
How much performance improvement can I expect?
Typically 30–80% improvement in task-specific accuracy compared to the base model. The exact gain depends on data quality and task complexity — I show you benchmarks as proof.
Do I own the fine-tuned model after delivery?
Yes! You receive full ownership — the fine-tuned model weights (for open-source models) or your OpenAI fine-tune ID. No restrictions, no ongoing fees to me.
