Maia 300 is Microsoft’s custom AI accelerator chip, while Azure Maia refers more broadly to the accelerator family and the software, networking, memory, racks, cooling, and datacenter systems built around it. Microsoft has detailed how Azure Maia 300 will connect memory, compute, and networking for large-scale AI inference. The design builds on the Maia 300 system Microsoft plans to deploy in 2027, described in its
multi-gigawatt rollout plans, with a new focus on how the hardware operates as one system.
