1. Perplexity Moved Its Full Model Lifecycle Onto Crusoe Cloud

Perplexity. Crusoe and Perplexity announced a multi-year partnership that consolidates training and serving on one platform: Perplexity trains frontier models on Crusoe’s dedicated NVIDIA GB300 NVL72 clusters with InfiniBand interconnect, then serves them in production through Crusoe’s Managed Inference service. The deal runs both directions — Crusoe is adopting Perplexity Enterprise Pro and Max for its 1,800 employees for web and internal knowledge search, multi-step research, and data analysis. Source
