RTMDet

We don't benchmark RTMDet.

It is an open-weight model from OpenMMLab under the GPL v3 license, and commercial use requires open-sourcing your code or a commercial license.

RTMDet Overview

RTMDet is a real-time object detection model developed by OpenMMLab, released in December 2022 under the GPL-3.0 license. It adopts a single-stage detection architecture with large-kernel depthwise convolution in both the backbone and neck, enabling it to capture long-range spatial dependencies without the computational cost of full self-attention. The model family spans from RTMDet-tiny to RTMDet-x, covering a wide range of speed-accuracy operating points.

RTMDet License

GPL-3.0 · Restrictive license

RTMDet is released under GPL-3.0, a restrictive license. The RTMDet 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 RTMDet 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 RTMDet licensing question before you build on it, not after.
