Google unveiled eighth-generation TPUs (TPU 8t and TPU 8i), specialized hardware variants designed for world models, agentic AI, and reasoning-heavy architectures. TPU 8t optimizes for large-scale pre-training with 9,600 chips per superpod and features a SparseCore accelerator for embedding workloads; TPU 8i targets real-time inference. Both integrate Arm-based Axion CPU headers to eliminate data-preparation bottlenecks and form the core infrastructure of Google Cloud's AI Hypercomputer.
