### AI overview

The Khronos OpenCL Working Group has released OpenCL 3.1, moving field-proven capabilities into the core specification. The release mandates SPIR-V kernel ingestion for conformant implementations and expands cross-platform availability through a growing implementation, compiler, runtime, and framework ecosystem.

### Source excerpt

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.

### AI overview

The OpenCL Working Group has published a working draft of the cl_khr_cooperative_matrix extension, developed with Arm, Intel, and Qualcomm. The extension brings cooperative matrix operations for ML inference to OpenCL, while a companion OpenCL C extension is also being developed. Community feedback is requested before the standards are finalized.

### Source excerpt

The OpenCL Working Group has published a draft extension (cl_khr_cooperative_matrix) that brings cooperative matrix operations--a key technology for accelerating ML inference--to OpenCL, developed in collaboration with Arm, Intel, and Qualcomm. A companion extension to expose these capabilities directly in the OpenCL C language is also in progress, and the community is invited to review both drafts and provide feedback before they are finalized.
