December 2025 performance month focused on expanding model support and improving reliability across ROCm kernels. Delivered layout-flexible BQuant GEMM and inter_dim=192 support for CK 2stage MoE with targeted performance tuning, resulting in broader hardware compatibility and better suitability for large-scale models like Qwen3-235B. Stabilized builds and tests around new feature sets to reduce integration risk.

November 2025 monthly summary for ROCm/composable_kernel (CK_TILE): Delivered substantive enhancements to 2D quantized GEMM and CK_TILE tiling performance, coupled with targeted build fixes to improve reliability of the quantization workflow. Key outcomes include enabling 2D block-scale GEMM support for B-matrix quantization with configurable M/N/K quantization groups, refining tile distributions and UniversalGemmBasePolicy to optimize tensor layouts and CK-Tile performance, and ensuring robust CK_TILE builds and example correctness. Also aligned legacy Non-K Major paths with CK-Tile for compatibility and updated documentation and changelog to reflect new capabilities.
