[H3] OpenCL 3.1 is Here

May 4, 2026

opencl

On the eve of IWOCL 2026, the Khronos® OpenCL Working Group has released OpenCL™  3.1, bringing widely deployed, field-proven capabilities into the core specification to expand functionality, including SPIR-V ingestion, that developers will be able to rely on across conformant implementations. The new specification arrives into a growing OpenCL ecosystem, with implementations from multiple silicon vendors, particularly in mobile and embedded markets, and higher-level frameworks including SYCL™  and chipStar increasingly targeting OpenCL as an acceleration backend. The open-source compiler and runtime ecosystem around OpenCL also continues to mature with layered implementations of OpenCL over Vulkan and DirectX 12 — widening OpenCL’s cross-platform availability, including on platforms without native drivers.

[H3] Khronos at 25: Shaping Visual Computing with Open Standards

February 10, 2026

khronos_ecosystem

In 2025, Khronos reached an impressive milestone: 25 years of member-driven open standards development. The graphics, compute, and media landscape looked wildly different in 2000, when Khronos was formed, than it does today. Era-defining technologies such as smartphones, cloud computing, and the metaverse hadn’t yet emerged into the marketplace. The founders of Khronos were on the forefront of these emerging technologies. They knew that without flexible, consensus-driven interoperability standards, these nascent technologies would be severely limited by fragmentation and duplication of efforts–and that, conversely, open standards had the potential to foster a marketplace of interoperable technologies that would allow innovation to thrive.

[H3] Simplifying Vulkan One Subsystem at a Time

February 5, 2026

vulkan

When those of us in the Vulkan® working group want to modify the API—whether it’s a new hardware feature to expose, a new use case we want to address, or even just a gap in the spec we want to address—we have one invaluable tool that we make heavy use of: extensions! Extensions are a wonderful way for us to get improvements to the Vulkan API out to developers without waiting for a new core version. They let vendors expose novel functionality and enable us to gather community feedback on new features before we firm them up into a core specification. Amazing! So we get new functionality out to developers quickly—what’s not to love!? Well…

[H3] VK_EXT_present_timing: the Journey to State-of-the-Art Frame Pacing in Vulkan

December 4, 2025

vulkan

Real-time graphics evolved quickly through the 1990s and 2000s, but developers struggled with one persistent bottleneck: precise control over when frames appeared on screen. Early APIs like OpenGL relied on opaque buffer-swapping behavior that made smooth frame pacing difficult, often causing choppy motion even at high frame rates. Modern APIs introduced swapchains to improve throughput, yet still prioritized raw FPS over accurate presentation timing. Vulkan followed this pattern, offering strong pipelining but little insight into when queued frames would actually be shown. Early extensions such as VK_GOOGLE_display_timing and VK_KHR_present_wait moved the needle but lacked the precision developers needed. After years of iteration, the new VK_EXT_present_timing extension finally brings explicit, time-based presentation control to Vulkan, marking a significant step toward consistently smooth frame pacing in interactive applications.

About The Khronos Group

Every industry needs effective open
standards, and Khronos members from around the world cooperate to drive the open standards that are
helping to grow markets, reduce engineering costs, and accelerate time-to-market, while still enabling companies to
innovate and differentiate. We believe that open interoperability standards should be built by the industry, for the
industry, with rigorous specifications and conformance tests to enable consistent cross-platform experiences that
help make technology truly pervasive.
The Khronos Group is an open, member-driven consortium that provides a space for the
creation of the interoperability standards that enable developers to harness the full power of 3D graphics, XR (VR
& AR), parallel computing, machine learning, vision processing and the metaverse. Our portfolio of industry
standards includes: 3D Commerce, ANARI, glTF, Kamaros, KTX, NNEF, OpenCL, OpenGL, OpenGL ES, OpenVG, OpenVX, OpenXR,
SPIR, SYCL, Vulkan, WebGL and a number of Safety Critical derivatives, including Vulkan SC, SYCL SC, OpenGL SC and
the OpenVX safety critical profile.

Individual Member Representatives

We are a non-profit organization, and the standards we create are open and royalty-free for the industry to use. We
have been developing open standards for over 20 years and continue to grow, with over 180 member organizations contributing to the process, from large corporations to small
start-ups, academic institutions and individuals. View the Khronos History Timeline.
Each Khronos standard is driven by a Working Group where member representatives work together to develop a
specification and its associated ecosystem. Working Groups are managed by elected Working Group Officers.
Khronos operates under a multi-organization governance model where each member organization gets one vote, in order
to avoid single-organization control or dependency. A Board of Directors
oversees Khronos’ activities.
[H2] Open and Inclusive
The Khronos Group's members are at the core of everything we do, working to develop and maintain every standard we
produce through collaboration. To help our members thrive, we are working to ensure they feel as welcome and
included as possible, to ensure they have every opportunity to contribute, and to support them to create the best
standards they can. Take a look at our Diversity, Equity, Inclusion, and Belonging page to
find out what we're doing to make Khronos a safe space for everyone.
[H2] Building Ecosystems
Our Working Groups produce far more than just specifications; providing a high quality experience with our standards requires a rich ecosystem of tools and educational
materials that will help drive the widespread adoption of the standard. These materials can include sample
implementations, conformance tests, Software Development Kits (SDKs), user guides, code samples, and tutorials. A
lot of these are produced in public either wholly or in part via open source repositories, such as those on our GitHub page. We also have active outreach programs including news updates, webinars and events, and newsletters,
to ensure that all the latest developments and ecosystem updates are shared with the wider community.
[H2] Adopting a Khronos Standard
Any developer or organization can access Khronos API Specifications and implement and ship products using the
specification completely free of charge, royalty or licensing. However, to ensure that Khronos standards are
consistently implemented across multiple platforms, any organization developing a product that implements a standard
must pass that standard’s official Conformance Test Suite (CTS) before it can use the trademarked name or
logo, or call their product ‘compliant’ or ‘conformant’. Becoming an Adopter is independent of Khronos membership and there is typically
a modest fee to support development and quality testing of our standards.
[H2] Become a Khronos Member or Adopter
Become a Khronos member to help define, develop, and evolve the open standards that are critical to your business and
benefit the wider industry, or become a Khronos Adopter to gain IP and trademark protection for your conformant
implementation of a Khronos standard.
Khronos has multiple levels of membership, to enable any organization, large or small, to get involved. See our list of current Khronos Members. All members have access to any Working Group that is
driving a standard and any organization is welcome to join.

General enquiries email: .(JavaScript must be enabled to view this email address)
[H2] Industry Liaisons
Khronos works with a wide range of industry associations and Standards Developing Organizations (SDOs) that may
influence our activities. These cooperative Liaisons enable representatives from
participating organizations to share feedback on use cases and requirements to help coordinate and cooperate between
SDOs and member companies to foster a more integrated standards ecosystem.
[H2] Khronos Advisory Forums
Successful industry standards incorporate the requirements and feedback from a wide range of industry experts.
Khronos understands that not everyone is able to become a member and so have established a number of Advisory Panels and Forums to enable invited non-member advisors to share their requirements
and provide feedback on draft specifications. Advisors are always welcome to join Khronos to enjoy the full member
benefits of contributing to our standards.
[H2] Proposing New Open Standards
Khronos members and non-members can propose a new collaborative standardization activity by following our New Initiative Process. The Khronos Board will carefully consider
each proposal to ensure that it meets the required criteria so that we invest in proposals where there is strong
momentum and a good chance of wide adoption. Successful proposals
will be encouraged to form an Exploratory Group to gather further industry feedback and cooperation before a Working
Group is formed and the detailed specification work can start.
[H2] The Khronos IP Framework
Khronos operates a robust IP Framework that enables its members and adopters to
contribute, develop, and implement royalty-free open standards. The framework balances two important goals:
Providing protection for bona fide implementers so that Khronos members and adopters will not assert IP rights
or demand royalties.
Minimizing licensing obligations to protect members and adopters valuable IP portfolios.
In broad summary, members and adopters agree not to assert their patents against conformant implementations of a
standard. The Khronos Group itself does not own or hold any patents.
“Khronos standards are globally recognized and deployed in a wide variety of markets and products. Our success is testament to the significant ongoing member contributions that drive the evolution of open interoperability standards that are vital to both our members and the industry.
”
Neil Trevett, President, The Khronos Group.
