IonRouter
AI inference infrastructure company powering high-throughput, low-cost inference.
Our Take
Most inference platforms make you pay for a dedicated GPU per model, which is honestly wild when you think about it. Cumulus Labs built IonAttention — their custom inference stack — to multiplex multiple models onto a single GPU, so teams running LoRAs, fine-tuned variants, or a whole model zoo in production stop burning money on idle capacity. IonRouter ships zero cold starts and per-second billing, which sounds minor until you've been charged by the minute for GPU time you used for 12 seconds at 3am. If you're scaling multi-model infrastructure without a solve like this, you're leaving actual money on the table.
