### 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.
