SynthAPI

SynthAPI is a synthetic data generation platform designed specifically for fine-tuning and evaluating large language models. It enables AI teams to create diverse, high-quality training datasets using templates, seed prompts, and controlled noise injection. The platform supports multi-turn conversations, domain-specific terminology, and bias mitigation filters. SynthAPI recently launched a collaborative workspace where domain experts can annotate and review generated samples, and a proprietary quality scoring engine based on human preference signals. It integrates directly with Hugging Face, AWS SageMaker, and PyTorch. Adopted by AI startups needing rapid, low-cost synthetic data for RAG pipelines and instruction tuning.
