Rebellions introduces REBEL-Quad and REBEL-IO—chiplet-based inference accelerators purpose-built for hyperscale and enterprise AI workloads. With a multi-chiplet architecture, HBM3e, and UCIe-Advanced interconnect, the system delivers exceptional compute density and energy efficiency, outperforming leading GPUs in throughput-per-watt across models like LLaMA-70B and 405B. The demo highlights single-card inference performance, demonstrating high efficiency and low power consumption even for large models. Powered by a production-ready software stack compatible with PyTorch, vLLM, and Triton, Rebellions offers a sustainable, deployable alternative for next-gen AI infrastructure.
