NVIDIA Exemplar Cloud status technical
"IREN has achieved NVIDIA Exemplar Cloud status on NVIDIA GB300 NVL72."
direct-to-chip liquid cooled AI Cloud deployments technical
"four 50MW (IT load) direct-to-chip liquid cooled AI Cloud deployments scheduled"
IT load technical
"four 50MW (IT load) direct-to-chip liquid cooled AI Cloud deployments"
vertically integrated model financial
"reflects the agility of IREN’s vertically integrated model, which provides end-to-end control"
A vertically integrated model is a business structure in which a company controls multiple steps of its supply chain—such as raw materials, manufacturing, distribution and sales—rather than relying on outside suppliers or partners. For investors this matters because integration can lower costs, improve quality control and speed up delivery like a bakery that grows its own wheat and runs its own shops, but it also ties up capital and concentrates operational risk.
AI training and inference technical
"delivering data centers, compute and software for AI training and inference."
Training is the process of teaching a machine-learning system by feeding it lots of examples so it learns patterns, like a chef practicing a new recipe until it knows the steps. Inference is when the trained system uses what it learned to make predictions or decisions in real time, like the chef cooking a dish for a customer. Investors care because training drives upfront costs, data and infrastructure needs, and model quality, while inference determines day-to-day performance, scalability, revenue potential and ongoing operating costs and risks.
