I present PEPPER, a new portable parton-level event generator. It runs on a variety of CPU and GPU architectures of today’s rapidly changing HPC landscape, and delivers 1-2 orders of magnitude faster throughput for tree-level calculations at high jet multiplicities. The following ongoing developments in the framework are highlighted: ML-accelerated phase-space generation, the work towards GPU acceleration of higher-order calculations, and physics-driven improvements of the numerical stability in the infrared limits.
