YOLO-Face is a collection of open-source face detection datasets and pre-trained models on Roboflow that you can test, download, or fine-tune into a custom face detector.
Face detection is one of the most common starting points in computer vision: finding where the faces are in an image or video frame. YOLO-Face is the collection of open-source face detection datasets and pre-trained models on Roboflow built for exactly that, with dozens of projects you can test in your browser, download, or fine-tune into your own model.
In this guide, we'll cover what YOLO-Face is, what you can build with it, how to train your own YOLO face detection model on Roboflow, and how to use it responsibly.
What Is YOLO-Face?
YOLO-Face is a Roboflow Universe collection of face detection datasets and pre-trained models. Universe hosts dozens of community face detection projects, more than 40 in fact, ranging from general human face detection to expression detection, thermal and infrared faces, and even animal faces. Each one is testable in the browser, downloadable as a labeled dataset, and deployable via API.
At its core, YOLO-Face is about one job: drawing a bounding box around every face in an image. That sounds simple, but it is the foundation that everything else, blurring, counting, attribute analysis, recognition, is built on top of. Get reliable face detection first, and the downstream steps become tractable.
The face detection projects in the collection are trained on a range of YOLO model families. The three most recent are worth knowing, since you can fine-tune any of them on a forked face dataset in Roboflow Train:
- YOLO26: the newest YOLO family, an end-to-end model that removes Non-Maximum Suppression for lower latency and is optimized for fast CPU and edge inference. It is a strong fit for face detection that has to run in real time on-device, for example blurring faces in a live video feed.
- YOLO12: an attention-centric YOLO variant that brings transformer-style attention (area attention) into the real-time YOLO design for stronger accuracy on small and crowded objects. That helps on face detection in busy scenes, like counting faces in a crowd where each one is small.
- YOLO11: the widely adopted family supporting detection, segmentation, pose, and classification across nano-to-extra-large sizes. It is the most common base for community face detectors today, including the YOLOv11 Face Detection project in the collection, where it is trained to box human faces.
What You Can Build With YOLO-Face
A face detection model is a building block. Some of the things teams build on top of it:
Privacy redaction. Detect faces and blur or mask them automatically, for releasing footage, anonymizing datasets, or complying with privacy requirements. This is one of the most common and least sensitive uses: detection in service of removing identity, not capturing it.
Counting and analytics. Count people in a space, estimate occupancy, or measure attention and dwell in retail and events, all from face or head detection without identifying anyone.
Expression and attribute analysis. With custom classes, a detector can flag visible attributes like expression (some Universe projects already do face expression detection). This is analysis of a visible state, separate from identifying the person.
Safety and access workflows. Detect whether a face is present at a workstation, a kiosk, or a secure area as a trigger for downstream logic, without necessarily matching identity.
A recognition pipeline, if you genuinely need it. Detection plus a separate face-embedding and matching step is what identity recognition requires. The detector finds and crops the face; a downstream model turns that crop into an embedding and compares it against a gallery.
How to Build a Face Detection Model on Roboflow
You can go from a public dataset to a deployed face detector in an afternoon.
Start from a dataset. Browse the YOLO-Face collection on Universe and fork a face detection project into your workspace, or upload and label your own images in Annotate with AI-assisted labeling. For a first model, a few hundred representative images covering your real conditions (lighting, angles, distances, occlusion) beats a huge but narrow set.
Train the model. In Roboflow Train, we recommend training RF-DETR, Roboflow's state-of-the-art real-time detection architecture. It leads current YOLO releases on accuracy and latency, and it ships under a commercial-friendly license (more on that below). YOLO models are supported on the platform too if you specifically need them. But RF-DETR is the recommended starting point for new face detection projects.
Evaluate honestly. Check class-wise performance and test on images that look like your real deployment, not just clean samples. For faces, pay attention to performance across different lighting, angles, and demographics; a model that works on one population and not another is not ready.
Deploy where you run. Serve the model with Inference on the cloud or the edge, and chain it with logic in Workflows: detect faces, then blur them, count them, or pass crops to a downstream step. On-device deployment keeps face data local, which is often the right call for this use case.
Improve with real data. Use active learning to collect the frames your model is unsure about and fold them back into the next version.
Licensing: Check Before You Ship
If you do build on a YOLO model for face detection, note the license. The Ultralytics YOLO family is distributed under AGPL-3.0, a strong copyleft license that, in practice, requires open-sourcing the application you build around the model or buying a commercial license, even for many commercial uses. We covered the details in why AGPL-3.0 is a risk for computer vision teams.
RF-DETR is released under the Apache 2.0 license, free to use commercially with no copyleft obligations, which is one more reason it is our recommended model for a custom face detector you intend to ship.
YOLO-Face Conclusion
YOLO-Face is the fastest way to get started with face detection on Roboflow: dozens of open datasets and models to test, download, or fine-tune. The model itself does one thing well, finding faces, and that detection is the foundation for redaction or counting, analysis.
