Distributed fine-tuning platform

Fine-tune your models, on your hardware.

Run training jobs across multiple machines with real-time monitoring. Parsyn handles coordination.

Parsyn is now available!

A glimpse of what you'll use to manage your training jobs.

parsyn / dashboard

Monitor all your training jobs at a glance with live metrics and progress.

What it does

Run fine-tuning jobs on any hardware you control.

01

Use any GPU

Connect machines from anywhere. Each GPU picks up jobs when available.

02

Watch training live

See loss curves, resource usage and progress in real-time. No refreshing.

03

Crash-resistant

Auto checkpoints. If a worker dies, training picks up where it left off.

04

Your data, any format

Upload JSONL, CSV or Parquet. Automatic validation and preprocessing.

How it's built

Three layers that talk to each other and stay in sync.

How it works

Four steps from raw data to a trained model.

01

Upload your data

Drop your training data in JSONL, CSV or Parquet. Parsyn checks the format and indexes it.

Configure the job

Pick a base model from HuggingFace or bring your own. Set learning rate, batch size, epochs.
