# Operation Set `opset1` Specification {#openvino_docs_ops_opset1}

This specification document describes `opset1` operation set supported in OpenVINO.
Support for each particular operation from the list below depends on the capabilities available in a inference plugin
and may vary among different hardware platforms and devices. Examples of operation instances are expressed as IR V10 xml
snippets. Such IR is generated by the Model Optimizer. The semantics match corresponding nGraph operation classes
declared in `namespace opset1`.
