LM Data Tools launches synthetic data suite

LM Data Tools is an open-source FastAPI suite for generating training data for LLM fine-tuning. It covers Q&A pairs, conversations, persona rewrites, reasoning traces, long-form documents, and dataset mixing, with support for hosted and local models like OpenAI, Hugging Face, LM Studio, and Ollama.

// ANALYSIS

This is the kind of unglamorous plumbing that becomes valuable once teams need repeatable synthetic data pipelines instead of one-off scripts.

–The FastAPI UI and background job handling make the workflow accessible beyond power users who live in the terminal.
–The toolset is broad enough to cover most pre-finetuning workflows, from source scraping to multi-round conversation generation.
–Local-model support is the standout detail for privacy-sensitive teams or anyone building offline.
–The repo still looks early-stage, with 0 stars and no published releases, so the real test will be how stable the prompts, jobs, and outputs are in practice.
