Fine Tuning Data Generator
Generate production-ready LLM fine-tuning datasets with bias detection and format conversion
What You Can Do
You can transform domain specifications or seed examples into large-scale, production-ready fine-tuning datasets. This skill automatically generates diverse prompt-completion pairs, applies multi-strategy data augmentation (paraphrasing, perspective shifts, difficulty variation), detects and flags bias across demographic dimensions, and formats output in the exact structure required by major LLM fine-tuning platforms.
Features
Creates diverse, contextually relevant pairs from domain specifications or seed examples
Applies paraphrasing, perspective shifts, and difficulty variations to expand datasets
Identifies potential biases across demographic dimensions and output patterns before deployment
Outputs JSONL for OpenAI, Hugging Face Datasets format, and Anthropic MessagePack standards
Calculates diversity scores, balance ratios, prompt entropy, and completion variance
Tracks provenance, transformation history, and quality indicators for reproducibility
Handles 100-5,000 example datasets efficiently with parallel augmentation
Adapts generation strategies for legal, medical, technical, and business use cases
Example Output
Input: Domain specification for customer support fine-tuning
Generated dataset (sample):
{"prompt": "A customer asks for a refund on a purchase. How should support respond?", "completion": " Acknowledge the request, ask for the order number, and explain the refund policy."}
{"prompt": "Customer wants to return an item within 30 days. What's the process?", "completion": " Check the purchase date, verify eligibility, generate a return label, and process the refund."}
Quality report: ✓ Diversity score: 0.87 | ✓ Balance: 92% | ✓ No demographic bias detected | ✓ Formatted for OpenAI fine-tuning API
Output formats: Ready-to-upload JSONL files for OpenAI, Hugging Face datasets, or Anthropic fine-tuning pipelines.
