During September 2025, Ahmed contributed to the unslothai/gpt-oss repository by delivering targeted performance enhancements for the Metal backend, focusing on the Mixture of Experts (MoE) prefill path. He implemented benchmarking for prefill operations across varying prompt lengths and batch sizes, optimizing dense matrix multiplication and attention output kernels using C++ and Metal. Ahmed also developed specialized Metal kernels for MoE prefill, including gather_and_accumulate and scatter operations, and refined routing buffers to improve inference efficiency. His work demonstrated depth in GPU programming and performance optimization, addressing scalability and stability in machine learning workflows without introducing critical bugs during the period.
