YOLOv7

We don't benchmark YOLOv7.

It is an open-weight model from Academia Sinica under the GPL v3 license, and commercial use means releasing your source code under GPL-3.0.

YOLOv7 Overview

YOLOv7 is a real-time object detection model developed by Chien-Yao Wang and Hong-Yuan Mark Liao at Academia Sinica, released in July 2022 under the GPL-3.0 license. It introduces Extended Efficient Layer Aggregation Networks (E-ELAN) for improved gradient flow in the backbone, and trainable bag-of-freebies techniques including coarse-to-fine lead guided label assignment and auxiliary heads that improve accuracy without adding inference cost.

YOLOv7 License

GPL-3.0 · Restrictive license

YOLOv7 is released under GPL-3.0, a restrictive license. The YOLOv7 license permits commercial use, but it requires you to open-source any code changes you make, so businesses that cannot release related code need a separate commercial license.

Commercial use: Permitted with obligations: you can sell products built on YOLOv7 only if you also release the corresponding source under GPL-3.0. A commercial license removes that obligation.
Modification: Permitted. Modified versions you distribute must be released under GPL-3.0, with your changes documented.
Redistribution: Permitted with the corresponding source code and the license text.

Uncertainty around licensing can delay or stop a project. If you are commercially unwilling or legally unable to open-source related code, settle the YOLOv7 licensing question before you build on it, not after.
