Presents QGen Studio, a platform for LLM-driven QA dataset generation, LoRA fine-tuning via MLX, dataset visualization with quality metrics, and side-by-side model comparison.

Problem

Niche domains lack tailored QA datasets, and existing tools for synthetic QA dataset creation, quality inspection, and model training/comparison limit user control over generation and make datasets hard to understand.

Approach

An interactive end-to-end studio that combines document upload, few-shot example prompting, LLM-based QA generation with n-gram/TF-IDF/cosine quality metrics, a dataset viewer that highlights source context, LoRA fine-tuning on Apple Silicon via MLX, and a model explorer for side-by-side comparison.

Key results

Limitations

Experimental setup

Datasets: user-uploaded documents (JSON, PDFs, URLs converted via Docling)

Metrics: BLEU ROUGE METEOR TF-IDF cosine similarity

Builds on: LoRA Docling MLX
