This is LightlyTrain

How LightlyTrain Works

It covers the entire model development lifecycle from pretraining DINOv2/v3 vision foundation models on your unlabeled data to fine-tuning transformer and YOLO models on detection and segmentation tasks for edge deployment.

Pretraining

Pretrain

Pretrain DINOv2 foundation models on your domain data.

Autolabel

Generate high-quality pseudo labels for detection and segmentation tasks

Distill

DIstill knowledge from DINOv2 or DINOv3 into any model architecture.

Fine-tuning

Detection

Train LTDETR detection models with DINOv2 or DINOv3 backbones.

Segmentation

Train EoMT segmentation models with DINOv3 backbones

Classification

Train image classification models with any backbone

Experience the LightlyTrain Difference

See how LightlyTrain transforms the model training experience from complex to simple with Self-Supervised Learning.

Without LightlyTrain

You need large amounts of labeled data to get started.
You can’t implement SSL without deep ML expertise.
You're limited to general-purpose backbones.

With LightlyTrain

Start training immediately—no labeled data needed.
Get a pretrained model in just a few lines of code.
Cut down your model development cost and time in half.
Quick pretrain

Say Goodbye to Labels, Hello to Better Models

Manual annotations slow you down. Complex pretraining frameworks create roadblocks.
With LightlyTrain, you can pretrain powerful models in minutes—just install, run, and deploy.
