Launch HN: IonRouter (YC W26) – High-throughput, low-cost inference
product-launch

Cumulus Labs launches IonRouter, a low-cost inference API optimized for open-source and fine-tuned models, backed by IonAttention—a custom C++ inference runtime designed specifically for NVIDIA GH200 hardware architecture that achieves 588 tokens/s on multimodal workloads through novel optimizations around cache coherence, KV block writeback, and attention scheduling.
