Annotate. Train. Deploy. All under one license.

If you use Ultralytics YOLO code, models, architectures, training pipelines, or trained/fine-tuned models, you must either:

• Open-source your entire project under AGPL-3.0, or
• Obtain an Ultralytics Enterprise License.

This applies even if you:

• Train your own model from scratch
• Do not use pretrained weights
• Use YOLO only internally or for R&D
• Deploy through a SaaS platform, API, or other private system
• Embed it in hardware, edge devices, or commercial products

Under Ultralytics AGPL-3.0 guidance, compliance means publicly releasing the complete corresponding source code for the entire derivative work, including the larger application, modifications, scripts, configuration files, and, where applicable, model weights. If you do not want to open-source the full project, you need an Enterprise License. Ultralytics' customer licensing explainer also states that proprietary commercial embedding is covered by Enterprise, as shown in the Chef Robotics example.

To purchase an Enterprise License, simply fill out the request form above, and we'll be in touch within 24 hours.

The Enterprise License offers flexible options depending on your needs. Licenses can be scoped for a specific project, covering all team members working on that project, or for your entire organization, covering all members. Reach out to discuss which scope best fits your use case.

Our licensing is tailored to each organization's size and specific use case, ensuring a fair and customized solution. Please fill out our license request form to receive a tailored quote based on your needs.

Yes. All Ultralytics YOLO trained models fall under the AGPL-3.0 License by default. The AGPL-3.0 License covers the training code and the models produced by that training code.

Please see our Ultralytics Enterprise Software License Terms page for complete details.

No, a separate Enterprise License is not required for each Ultralytics product. With this license, you will have access to the complete Ultralytics YOLO source code portfolio, including YOLO26, earlier YOLO versions, and any future YOLO models that Ultralytics may release during the license term. This includes:

• Pretrained models
• Supporting documentation
• Subsequent modifications, including enhancements, upgrades, new features, bug fixes, and repairs

If you have any other questions, please reach out to us via the request form above.

An Enterprise License provides organizations with the ability to modify Ultralytics YOLO source code and embed Ultralytics YOLO code and models in commercial products without needing to follow the constraints of the AGPL-3.0 License, namely the requirement to open-source modified works or larger works containing Ultralytics YOLO code and models.

This gives organizations full flexibility to develop proprietary products and services containing Ultralytics YOLO code and models.
