# Train Three New RF-DETR Model Sizes

<figure><img src="/files/ph1U9j9bUWO1jfYYyyQj" alt=""><figcaption></figcaption></figure>

You can now train three new RF-DETR model sizes in the Roboflow platform:

* Nano
* Small
* Medium

These models are available in addition to the Base model size we released earlier this year.

RF-DETR Nano, Small, and Medium are all about as fast as YOLO11 models at the respective size while being significantly more accurate.

To train an RF-DETR model, go to a dataset version in a Roboflow project, click "Custom Train", and select RF-DETR. You will then be able to choose from the new model sizes.

All trained models can be deployed via Roboflow Workflows both in the cloud (with the [Roboflow Serverless V2 API](https://docs.roboflow.com/deploy/serverless-hosted-api-v2) or a [Dedicated Deployment](https://docs.roboflow.com/deploy/dedicated-deployments)), or on your own hardware (with Roboflow Inference).
