The Khronos Group is an open, member-funded industry consortium that develops and maintains royalty-free open standards for graphics, parallel computation, and related media on a wide range of platforms. Its members include hardware vendors, software companies, and platform owners who collaborate to define specifications, conformance tests, and the registries and tooling that let independent implementations interoperate. The consortium’s standards are published openly and are intended to be implementable by anyone without per-unit royalties.
Khronos became the steward of OpenGL in 2006. On July 31, 2006, the OpenGL Architecture Review Board voted to transfer control of the OpenGL specification to the Khronos Group, consolidating OpenGL work alongside Khronos’s other standards so that related efforts could cooperate more closely. Khronos established an OpenGL Working Group to control and evolve the standard, with the full transfer expected to complete in the third quarter of 2006 and continuity of support promised throughout the transition.
The consortium’s most prominent later achievement is Vulkan, the low-overhead successor to OpenGL. Khronos released the Vulkan 1.0 specification on February 16, 2016, describing it as the result of about 18 months of collaboration among hardware, game engine, and platform vendors, designed to give applications explicit, efficient control over modern GPUs while complementing OpenGL and OpenGL ES. Vulkan, like Khronos’s other APIs, is defined through a machine-readable registry that drives the generation of its header files.
Beyond OpenGL and Vulkan, Khronos hosts a broad family of standards. These include WebGL, which brings GPU-accelerated 3D graphics to web browsers; glTF, a compact runtime format for transmitting and loading 3D scenes and models; OpenCL, a framework for writing programs that execute across CPUs, GPUs, and other accelerators; and SPIR-V, the intermediate shader representation used by Vulkan and OpenCL. Together these cover real-time graphics, asset delivery, and general-purpose parallel computation.
Khronos operates a structured working-group process in which members propose, draft, and ratify specifications, and the consortium publishes conformance tests so that products claiming support for a standard can be validated. By keeping its specifications and registries open and royalty-free, Khronos has positioned its standards as cross-vendor foundations that span desktop, mobile, web, console, and embedded systems.
