Standard Portable Intermediate Representation (SPIR) is an intermediate language for parallel computing and graphics by Khronos Group. It is used in multiple execution environments, including the Vulkan graphics API and the OpenCL compute API, to represent a shader or kernel. It is also used as an interchange language for cross compilation.^[1]^[2]

SPIR-V is a new version of SPIR which was introduced in 2015 by the Khronos Group, and has since replaced the original SPIR, which was introduced in 2012.
