# Available Operations Sets

According to capabilities of supported deep learning frameworks and hardware capabilities of a target inference device, all operations are combined into operations sets each fully supported in a specific version of OpenVINO™ toolkit. 

This topic provides a complete list of available sets of operations supported in different versions of OpenVINO™ toolkit. It's highly recommended to use the actual version of the operations set for a particular release. For a list of operations included into an operations set, click a link in the table.  

| OpenVINO™ Version | Actual Operations Set            | 
| :---------------- | :------------------------------- | 
| 2021.1            | [opset4](opset4.md)   | 
| 2020.4            | [opset3](opset3.md)   |
| 2020.3            | [opset2](opset2.md)   |
| 2020.2            | [opset2](opset2.md)   |
