Fetched 2026-09-07: HTTP 200, <title> “RDU | Next-Gen AI Chip for Inference at Scale”. “The SambaNova RDU is purpose-built for inference”. TRAINING IS DELIBERATELY NOT ADDED: the page never claims it, and its own FAQ distinguishes the RDU from GPUs, which are “primarily for training”. The absence is the vendor's, not the record's.

The RDU page says "Combining RDU chips into racks powers the largest models with the fast inference." and its only route is "Talk to an expert"; the SambaRack page says it "combines 16 SN50 RDU chips in one rack". No page offers the chip on its own or states a price.
